Overview

This payment-integration skill is not clearly malicious, but it handles payment credentials and webhook data in ways that could expose secrets or financial records.

Review this skill before installing. Use it only with sandbox/test data unless you first harden the scripts: avoid pasting or printing real private keys, do not expose local services through ngrok without access controls, do not replay webhooks to production endpoints, restrict file permissions, redact logs, and fix the SFTP and signature examples before copying them into production code.

Vulnerability Patterns

• Insecure Skill Coding Practices: Finds exploitable flaws such as hardcoded secrets or command injection
• Skill Instruction Hijacking: Alters the agent's session goals or safety constraints when the skill loads
• Agent Memory Poisoning: Writes attacker-controlled rules into memory that affect later sessions
• Remote Payload Retrieval and Execution: Fetches external code whose behavior can change after review
• Embedded Malicious Code: Ships malicious scripts inside the skill and executes them locally

• Remediation: <![CDATA[ ## Remediation Suggestions 1. Bind the debugging listener to `127.0.0.1` by default rather than all network interfaces. 2. Require explicit, informed user confirmation before exposing any port through ngrok. 3. Verify the Alipay+ request signature, client identifier, timestamp, and replay window before accepting or logging a webhook. 4. Replace the raw netcat listener with an HTTP server that enforces request-body limits, timeouts, rate limits, and valid HTTP parsing. 5. Redact signatures, tokens, customer identifiers, payment codes, and other sensitive fields before logging. 6. Create the log with restrictive permissions: ```bash umask 077 install -m 600 /dev/null "$LOG_FILE" ``` 7. Add log rotation, retention limits, and maximum file-size controls. 8. Use synthetic test payloads for debugging rather than real production notifications. 9. Keep tunnel URLs short-lived and restrict access with ngrok authentication or an equivalent access policy. ]]>

• Finding: Predictable Temporary File Enables Symlink-Based File Overwrite<![CDATA[ ## Vulnerability Details **File Location**: `scripts/test-signature.sh`, lines 70-73 **Vulnerability Type**: Insecure predictable temporary file **Risk Level**: Medium ### Vulnerable Code ```bash # Verify signature echo "$signature" | base64 -d > /tmp/verify_signature.bin verify_result=$(echo -n "$notify_content" | openssl dgst -sha256 -verify "$public_key_file" -signature /tmp/verify_signature.bin 2>&1) || true rm -f /tmp/verify_signature.bin ``` ### Technical Analysis The script writes decoded signature data to the fixed path `/tmp/verify_signature.bin`. The `/tmp` directory is normally writable by every local user. Shell output redirection follows symbolic links and does not securely create a new, exclusive file. A local attacker can create `/tmp/verify_signature.bin` as a symbolic link to another file writable by the victim. When the victim runs the script, the redirection truncates and overwrites the linked target with attacker-influenced decoded data. The fixed name also creates a race condition between concurrent invocations. One process may replace, delete, or read the temporary data used by another process, producing incorrect verification results or unintended file operations. ### Attack Path 1. A local attacker predicts the fixed temporary path. 2. The attacker creates a symbolic link: ```bash ln -s /path/to/victim-writable-file /tmp/verify_signature.bin ``` 3. The victim runs signature verification. 4. The shell follows the symbolic link when processing `> /tmp/verify_signature.bin`. 5. The target file is truncated and overwritten with decoded signature bytes. 6. The script subsequently removes the temporary pathname, while the target file remains corrupted. ### Impact Assessment The attacker can overwrite or corrupt files writable by the account running the Skill. If the Skill is run by a privileged account, the scope increases to privileged configuration or application files that the account can modify. The issue does ...[truncated 269 chars]

The script should also validate Base64 decoding errors before invoking OpenSSL. ]]>

• Location: scripts/test-signature.sh:101
• Finding: Generated RSA Private Key Is Printed and May Be Stored with Permissive Permissions<![CDATA[ ## Vulnerability Details **File Location**: `scripts/test-signature.sh`, lines 101-118 **Vulnerability Type**: Private-key disclosure and insecure key-file permissions **Risk Level**: Medium ### Vulnerable Code ```bash private_key_file="$HOME/.openclaw/workspace/alipayplus_private_key.pem" public_key_file="$HOME/.openclaw/workspace/alipayplus_public_key.pem" # Generate private key openssl genrsa -out "$private_key_file" 2048 echo "✅ Private key generated: $private_key_file" # Generate public key openssl rsa -in "$private_key_file" -pubout -out "$public_key_file" echo "✅ Public key generated: $public_key_file" echo "" echo "⚠️ Note: This key pair is for testing only.

The resulting permissions therefore depend on the caller's environment and OpenSSL behavior. More importantly, the script prints the complete private key to standard output. Terminal scrollback, remote shell recording, CI logs, Agent transcripts, screen-sharing software, and command-output collectors can retain this material after execution. Although the script labels the key as test-only, nothing technically prevents a user from registering or reusing it in a real integration. Printing private-key material is unnecessary even for test workflows. ### Attack Path 1. A user chooses the RSA key-generation option. 2. The private key is generated in the OpenClaw workspace. 3. The entire key is printed to standard output. 4. ...[truncated 962 chars]

Display only the key path and a public-key fingerprint: ```bash openssl pkey -in "$private_key_file" -pubout | openssl pkey -pubin -outform DER | openssl dgst -sha256 ``` 5. Create the workspace directory with mode `0700`. 6. Warn users not to register test keys in production and prevent accidental reuse by storing test keys under an explicitly marked test directory. 7. For production, use a secret manager, hardware security module, or operating-system key store and perform signing without exporting the raw private key. ]]>

• Location: references/reconciliation-guide.md:172
• Finding: SFTP Example Disables SSH Host-Key Verification<![CDATA[ ## Vulnerability Details **File Location**: `references/reconciliation-guide.md`, lines 172-178 **Vulnerability Type**: Disabled server identity verification **Risk Level**: High ### Vulnerable Code ```java jsch.addIdentity(sftpKeyPath); Session session = jsch.getSession(sftpUser, sftpHost, 22); session.setConfig("StrictHostKeyChecking", "no"); session.connect(); ChannelSftp channel = (ChannelSftp) session.openChannel("sftp"); channel.connect(); ``` ### Technical Analysis The Java SFTP example explicitly sets `StrictHostKeyChecking` to `no`. This disables verification that the remote server presents the expected SSH host key. Encryption without server authentication is insufficient against an active man-in-the-middle attack. An attacker who can influence DNS, routing, a proxy, or the local network can impersonate the reconciliation server. The client will accept the attacker's host key without warning. The example uses a private-key identity and downloads financial reconciliation reports. Even where the SSH protocol does not directly reveal the client's private key, accepting an untrusted server permits connection interception, server impersonation, authentication probing, and delivery of forged reconciliation data. Because the Skill instructs users to consult and implement examples from this reference, the insecure setting may be copied into operational code. ### Attack Path 1. A developer copies the documented SFTP client example. 2. The deployed client runs with `StrictHostKeyChecking` disabled. 3. An attacker gains a position capable of redirecting the SFTP connection, such as compromised DNS or a hostile network gateway. 4. The attacker presents an arbitrary SSH host key. 5. The client accepts the fake server without checking a trusted host-key record. 6. The fake server returns manipulated settlement, transaction, summary, or fee files. 7. The forged files are processed by downstream reconciliation logic and may influence financial inv ...[truncated 587 chars]
• Remediation: <![CDATA[ ## Remediation Suggestions 1. Remove the `StrictHostKeyChecking=no` setting. 2. Maintain a dedicated `known_hosts` file containing the approved Alipay+ SFTP host key. 3. Configure JSch to use that file: ```java JSch jsch = new JSch(); jsch.setKnownHosts("/secure/path/alipayplus_known_hosts"); jsch.addIdentity(sftpKeyPath); Session session = jsch.getSession(sftpUser, sftpHost, 22); session.setConfig("StrictHostKeyChecking", "yes"); session.connect(); ``` 4. Obtain the host-key fingerprint through an authenticated out-of-band channel and verify it before deployment. 5. Fail closed on unknown or changed host keys. 6. Document a controlled host-key rotation procedure rather than instructing users to bypass verification. 7. Ensure the executable downloader uses a controlled known-hosts policy and an approved, fixed SFTP hostname. ]]>

• Location: scripts/generate-config.sh:121
• Finding: Configuration Generator Encourages Plaintext Private-Key Storage Without Restrictive Permissions<![CDATA[ ## Vulnerability Details **File Location**: `scripts/generate-config.sh`, lines 121-132 and 194-198 **Vulnerability Type**: Insecure credential storage and unsafe JSON construction **Risk Level**: Medium ### Vulnerable Code ```bash # 生成配置文件 config_file="$WORKSPACE_DIR/alipayplus-config.json" cat > "$config_file" << EOF { "alipayplus": { "environment": "$environment", "role": "$role", "partnerId": "$partner_id", "clientId": "$client_id", "credentials": { "privateKey": "-----BEGIN RSA PRIVATE KEY-----\\nYOUR_PRIVATE_KEY_HERE\\n-----END RSA PRIVATE KEY-----", "alipayPlusPublicKey": "-----BEGIN PUBLIC KEY-----\\nALIPAY_PLUS_PUBLIC_KEY_HERE\\n-----END PUBLIC KEY-----" }, ``` The generated file is then presented with these instructions: ```bash echo "" echo "⚠️ Pending tasks:" echo " 1.

Private key file recorded: $private_key_path" fi ``` ### Technical Analysis The generated configuration is explicitly structured to contain the complete application private key in plaintext. The script instructs users to replace the placeholder with the real private key. The file is created using ordinary shell redirection without setting `umask 077` or applying mode `0600`. For a newly created file under a common `022` umask, the configuration may be readable by other local users. If the workspace is backed up, synchronized, indexed, or committed, the embedded key may also propagate into additional systems. The script asks for a private-key path but does not use it to implement safer key indirection. Instead, the generated configuration still contains an inline private-key placeholder. The JSON is also constructed by interpolating unescaped user input into a heredoc. Quotes, backslashes, control characters, ...[truncated 1670 chars]
• Remediation: <![CDATA[ ## Remediation Suggestions 1. Do not store the raw private key in the generated JSON. 2. Store only a secret-manager identifier, hardware-key identifier, or path to a protected key file: ```json { "credentials": { "privateKeyPath": "/secure/path/alipayplus_private_key.pem" } } ``` 3. Set restrictive permissions before file creation: ```bash umask 077 mkdir -p -m 700 "$WORKSPACE_DIR" ``` 4. Explicitly apply mode `0600` after generation: ```bash chmod 600 "$config_file" ``` 5. Generate JSON with a proper serializer such as `jq --arg` instead of direct heredoc interpolation. 6. Validate role, environment, URLs, currency, timeout, and retry values before writing them. 7. Ensure private keys are excluded from source control, backups, diagnostic bundles, and workspace synchronization. 8. Prefer a secret manager or HSM for production signing so the private key is never stored in application configuration. 9. If a key path is requested, use that path in the generated configuration instead of instructing the user to paste key material inline. ]]>

Findings (31)

Tp4

High

• Category: MCP Tool Poisoning
• Confidence: 90% confidence
• Finding: The code is related to one declared area—asynchronous notification debugging—but only implements a subset of the overall described assistant functionality. More importantly, it includes undeclared capabilities such as exposing a local service publicly via ngrok and sending arbitrary HTTP POST replay requests. The script is a narrow webhook debugging tool, not a broader Alipay+ payment integration assistant for configuration, signature verification, and reconciliation processing. Therefore the declared description does not accurately represent this code chunk.

Tp4

High

• Category: MCP Tool Poisoning
• Confidence: 95% confidence
• Finding: The code partially aligns with the declared description because it supports signature verification testing and asynchronous notification signature debugging. However, the declared purpose presents a broader Alipay+ payment integration assistant with capabilities including configuration generation and reconciliation file processing, which are absent here. Additionally, the script includes an undeclared capability to generate RSA key pairs and display the private key content. That makes the actual code materially narrower in scope than the declared purpose while also adding a security-sensitive capability not explicitly mentioned.

• Confidence: 70% confidence
• Finding: Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.

Missing User Warnings

High

• Confidence: 98% confidence
• Finding: The documentation presents the Java SFTP example as normal usage while omitting any warning that it disables host key verification. This omission is dangerous because readers may copy the snippet directly, inheriting an insecure transport configuration that defeats server authenticity checks and exposes downloaded reconciliation data to interception or manipulation.

Intent-Code Divergence

High

• Confidence: 99% confidence
• Finding: The response/webhook verification example says to validate using response-time data, but the complete Java client passes the original requestTime into verify() and rebuilds the signed content with that value. This can cause valid signatures to fail verification or, worse, teach integrators to verify the wrong message components, undermining authenticity checks for responses and webhooks.

Tool Parameter Abuse

High

• Category: Tool Misuse

Content

echo "$signature" | base64 -d > /tmp/verify_signature.bin
    verify_result=$(echo -n "$notify_content" | openssl dgst -sha256 -verify "$public_key_file" -signature /tmp/verify_signature.bin 2>&1) || true

    rm -f /tmp/verify_signature.bin

    if [[ "$verify_result" == *"Verified OK"* ]]; then
      echo ""

• Confidence: 95% confidence
• Finding: Tool parameters are crafted to achieve unintended or unsafe behavior. Parameter abuse can bypass intended safety checks (e.g. shell=True, --force, dangerous glob patterns).

Missing User Warnings

Medium

• Confidence: 84% confidence
• Finding: This markdown file documents `getCurrentRegion` as obtaining the user's current location, but it does not include any warning about privacy implications, consent, or handling of location data. For markdown files, SQP-2 applies when descriptions omit warnings about behaviors that could affect user privacy.

Missing User Warnings

Medium

• Confidence: 91% confidence
• Finding: The onboarding flow explicitly tells users to fill configuration with a Partner ID, private key, certificates, and webhook URLs, but gives no warning about secure generation, storage, redaction, or avoiding disclosure in chat/session artifacts. In a skill intended to help configure payments, that omission can lead users to paste or persist live secrets insecurely, increasing credential leakage and downstream payment compromise risk.

Missing User Warnings

Medium

• Confidence: 92% confidence
• Finding: The troubleshooting flow instructs users to replay test notifications but does not restrict this to sandbox or isolated endpoints, nor warn about side effects on production business logic. Replaying payment webhooks against live systems can retrigger fulfillment, status transitions, or reconciliation actions if idempotency is weak or endpoints are misconfigured.

Missing User Warnings

Medium

• Confidence: 89% confidence
• Finding: The checklist explicitly includes location access, transaction history, API call logging, and security log review, but it does not require data minimization, consent, retention limits, redaction, or protection of personal and payment-related data. In a payment integration context, this omission can lead implementers to collect or retain privacy-sensitive data insecurely, increasing compliance and data exposure risk.

Missing User Warnings

Medium

• Confidence: 91% confidence
• Finding: The guide encourages automated download and local storage/processing of reconciliation files that clearly contain transaction identifiers, order references, amounts, and status data, but it does not warn users to treat these artifacts as sensitive financial records. Without guidance on secure storage, access controls, retention, redaction, and protected exports, adopters may expose regulated or business-sensitive data through local workspaces, logs, or generated reports.

Intent-Code Divergence

Medium

• Confidence: 99% confidence
• Finding: The Java SFTP example explicitly sets StrictHostKeyChecking to "no", which disables server host key verification and makes the client trust any host presenting itself as the server. This enables man-in-the-middle attacks, allowing interception or tampering of sensitive reconciliation files and credentials during transfer.

Sudo/Root Execution

Medium

• Category: Privilege Escalation

Content

```bash
# Ensure private key has correct permissions
chmod 600 $SFTP_KEY
```

### File Not Found

• Confidence: 80% confidence
• Finding: Commands invoke sudo or root privileges. Verify this elevated access is necessary and justified.

Intent-Code Divergence

Medium

• Confidence: 97% confidence
• Finding: The guide consistently specifies Base64Url for signatures, but the Java example uses standard Base64 encoding and decoding. Implementers who copy this sample may generate or verify incompatible signatures, causing verification failures or prompting unsafe workaround behavior such as disabling signature checks during integration.

Missing User Warnings

Medium

• Confidence: 88% confidence
• Finding: This markdown file includes an example of sending a `Client-Certificate` header containing Base64-encoded certificate content, which affects sensitive credential material and network transmission. The surrounding text explains how to do it but does not warn users about handling, exposure risk, or protecting certificate data in logs and transit.

Intent-Code Divergence

Medium

• Confidence: 96% confidence
• Finding: The retry section claims Alipay+ determines delivery success from response fields `result.resultStatus = S` and `result.resultCode = SUCCESS`, implying a structured response payload. However, the actual webhook handler returns `ResponseEntity.ok("SUCCESS")`, and the same section later states success requires HTTP 200 plus a response body containing `SUCCESS`, which contradicts the earlier requirement.

Intent-Code Divergence

Medium

• Confidence: 97% confidence
• Finding: The document gives conflicting signature-handling guidance: the prose says the signature should be base64url-decoded, while the Java example uses the standard Base64 decoder. If implementers follow the sample code against a base64url-encoded signature format, valid webhook signatures may be rejected, causing dropped or repeatedly retried payment notifications; in some stacks, developers may weaken verification to 'make it work,' creating a path to forged webhook acceptance. In a payment webhook integration guide, ambiguity in cryptographic verification instructions is especially risky because merchants often copy sample code verbatim.

Description-Behavior Mismatch

Medium

• Confidence: 83% confidence
• Finding: The manifest describes an Alipay+ payment integration assistant focused on configuration, signature verification, asynchronous notification debugging, and reconciliation processing. In practice, this script starts a raw local listener with netcat and can send user-supplied JSON to any target URL, which makes it a general-purpose webhook server/replay tool rather than an Alipay+-specific debugger.

Missing User Warnings

Medium

• Confidence: 95% confidence
• Finding: Incoming webhook requests are written verbatim to a persistent log file under the user's home directory without warning, minimization, or redaction. Payment notifications can contain personal data, transaction metadata, tokens, or signatures, so persistent plaintext logging creates unnecessary local data exposure and retention risk.

Context-Inappropriate Capability

Medium

• Confidence: 90% confidence
• Finding: The script can expose a local service to the public internet through ngrok, which materially expands the attack surface of the developer's machine or local webhook receiver. Although useful for webhook testing, the exposure is not constrained, authenticated, or accompanied by strong safety controls, so a user may unintentionally publish a sensitive local endpoint.

Missing User Warnings

Medium

• Confidence: 88% confidence
• Finding: Starting ngrok creates a public tunnel to the specified local port, which can affect system exposure and privacy. The script states that the port is exposed to the public network, but it does not provide a substantive safety warning or confirmation before enabling that exposure.

External Transmission

Medium

• Category: Data Exfiltration

Content

echo ""

    # Send POST request
    response=$(curl -s -w "\n%{http_code}" -X POST "$target_url" \
      -H "Content-Type: application/json" \
      -H "X-Alipayplus-Notification: true" \
      -d "$notify_content")

• Confidence: 70% confidence
• Finding: Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.

Missing User Warnings

Medium

• Confidence: 90% confidence
• Finding: The script creates a local directory and stores reconciliation CSV files, which likely contain financial transaction data. Although the script logs that files are being downloaded, it does not include any user-facing warning or comment about the sensitivity of the data, retention expectations, or the local storage impact.

Missing User Warnings

Medium

• Confidence: 88% confidence
• Finding: The script generates a JSON configuration file in a predictable workspace location and includes credential fields, including an embedded private key placeholder, without checking for existing files, restricting file permissions, or clearly warning that the output is sensitive. In a payment-integration context, configuration files commonly end up populated with real secrets, so accidental overwrite, unintended disclosure via permissive default umask, or later inclusion in logs/version control can expose payment-signing material and operational endpoints.
