• Latest audit: Sep 16, 2026 · 10:46 AM UTC
• Version: 0.0.1

Overview

The skill has a legitimate certificate-deployment purpose, but it gives an agent broad live-cloud authority and includes unsafe installation, credential, and private-key handling patterns that need Review before use.

Install only after reviewing the cloud permissions, using a least-privilege role, avoiding FullAccess policies, disabling automatic plugin updates unless separately approved, and never entering TLS private keys or cloud access keys into commands or chat. Treat resource creation, rollback, and job deletion as production changes that should require explicit, separate confirmation.

Vulnerability Patterns

• Skill Instruction Hijacking: Alters the agent's session goals or safety constraints when the skill loads
• Remote Payload Retrieval and Execution: Fetches external code whose behavior can change after review
• Unauthorized Access and Privilege Escalation: Obtains permissions beyond the task's legitimate needs
• Insecure Dependencies: Introduces malicious components through unsafe dependency sources
• Insecure Skill Coding Practices: Finds exploitable flaws such as hardcoded secrets or command injection

It deliberately maps requests that do not explicitly mention certificate deployment into the deployment workflow and then prevents normal intent recognition or use of other Skills. Explicit confirmation before a cloud-changing operation is a valid safeguard. However, an indefinite context or session lock that instructs the agent to ignore unrelated subsequent instructions is not necessar ...[truncated 1261 chars]

The `latest` archive name allows the effective payload to change after this Skill package has been reviewed. Displaying the first 50 lines of a setup script is not a security verification. Malicious behavior can be placed after line 50, hidden in sourced content, or downloaded dynamically by the setup script. The archive alternatives are even less protected because network output is streamed directly into `tar`. Moving the resulting binary into `/usr/local/bin` with `sudo` makes the downloaded executable available system-wide. ### Attack Path 1. A user follows the Skill's mandatory or recommended installation procedure. 2. The setup script or `latest` archive is retrieved from a mutable URL. 3.

Unpinned and Automatically Updated Cloud CLI Plugins

Content

View full analysis

[MUST] run `aliyun configure set --auto-plugin-install true` to enable > automatic plugin installation. > [MUST] run `aliyun plugin update` to ensure that any existing plugins are > always up-to-date. ``` ```bash aliyun upgrade ``` ```bash aliyun plugin install --names ecs vpc rds aliyun plugin list-remote ``` The API reference additionally recommends: ```bash pip install ossutil ``` ### Technical Analysis The Skill requires automatic installation and updating of executable plugins. This causes the code that runs during a future Skill invocation to differ from the code present during audit. The guidance generally does not pin plugin or Python package versions, verify hashes, or constrain the dependency source. Automatically selecting newly published versions increases exposure to compromised releases, repository takeover, dependency substitution, or malicious updates. The mandatory update is also broader than required for certificate deployment: it updates existing plugins, including plugins unrelated to the selected cloud product. ### Attack Path 1. The user enables automatic plugin installation as required by the Skill. 2. A needed or already installed plugin is fetched or updated automatically. 3. An upstream account, package, repository, or distribution channel publishes a compromised version. 4. The package is accepted without a pinned version or integrity verification. 5. The compromised plugin executes inside the authenticated Aliyun CLI workflow. 6. It can observe command parameters, profile names, cloud responses, and locally available credentials. ### Impact Assessment A malicious plugin or ...[truncated 359 chars]

Secrets supplied on a command line may be retained in shell history, exposed to process inspection, captured in terminal or agent logs, or included in diagnostics. Long-lived AK credentials stored locally also create a high-value credential file. These instructions directly conflict with `SKILL.md:110-113`, which states that literal credential values must never be supplied through `aliyun configure set`. Because the main Skill directs users to this reference, the contradictory unsafe examples remain actionable. ### Attack Path 1. The user follows the referenced configuration guide. 2. The user substitutes real AK/SK or STS values into the example command. 3. The command is recorded in shell history or observed through local process inspection. 4. The credentials are also persisted in `~/.aliyun/config.json`. 5. An attacker, diagnostic collector, or compromised local dependency reads one of these sources. 6.

Vulnerability Patterns

• Data Exfiltration: External Transmission, Env Variable Harvesting, File System Enumeration
• Privilege Escalation: Excessive Permissions, Sudo/Root Execution, Credential Access
• Excessive Agency: Unrestricted Tool Access, Autonomous Decision Making, Scope Creep
• Rogue Agent: Self-Modification, Session Persistence

Findings (27)

Vague Triggers

High

• Category: Not specified by scanner
• Confidence: 98% confidence

Finding

The skill explicitly routes vague inputs to deployment by default and forbids routing to other skills before clarification, which can capture unrelated certificate, instance, purchase, or query requests. Because this skill can make infrastructure changes, forced default routing materially increases the chance of unintended stateful actions and user confusion.

Content

No source excerpt is available for this finding.

Self-Modification

High

• Category: Rogue Agent
• Confidence: 98% confidence

Finding

The skill contains explicit self-modification behavior through aliyun upgrade and related installer execution, allowing the agent to change its own tooling during task execution. Self-update in-band is dangerous because it introduces non-deterministic behavior, expands attack surface, and may execute newly fetched code from external sources.

Context-Inappropriate Capability

High

• Category: Not specified by scanner
• Confidence: 96% confidence

Finding

The skill instructs the agent to create cloud resources when no matching target exists, which exceeds a deployment-only skill's stated purpose. Resource creation is a separate, potentially billable and security-sensitive operation that can change production infrastructure under the guise of certificate deployment.

Content

No source excerpt is available for this finding.

Description-Behavior Mismatch

High

• Category: Not specified by scanner
• Confidence: 97% confidence

Finding

The OSS binding example accepts raw certificate content and a private key, which exceeds the promised CAS one-click deployment model and introduces direct secret handling into the skill. Allowing an agent workflow to process private keys raises the risk of secret disclosure in prompts, logs, shell history, telemetry, or downstream tooling.

Content

No source excerpt is available for this finding.

Context-Inappropriate Capability

High

• Category: Not specified by scanner
• Confidence: 98% confidence

Finding

The documentation explicitly instructs passing --private-key and certificate PEM material on the command line, enabling direct handling of highly sensitive key material. Command-line secret passing is especially risky because private keys may be exposed via process lists, shell history, terminal logs, agent traces, or copied transcripts.

Content

No source excerpt is available for this finding.

Self-Modification

High

• Category: Rogue Agent
• Confidence: 90% confidence

Finding

Skill modifies its own code, configuration, or behavior at runtime. Self-modification enables an agent to escalate privileges, disable safety constraints, or install persistent backdoors.

Intent-Code Divergence

High

• Category: Not specified by scanner
• Confidence: 98% confidence

Finding

The file explicitly states that ALB APIs such as update-listener-attribute must not be used for certificate deployment and that deployment must go through the CAS DeploymentJob flow, yet the ALB flow later instructs Has HTTPS listener → Update certificate (update-listener-attribute). This contradiction can cause an agent to bypass the intended centralized deployment path, leading to incorrect certificate handling, inconsistent state tracking, and loss of the safety controls implied by the CAS workflow.

Content

No source excerpt is available for this finding.

Missing User Warnings

Medium

• Category: Not specified by scanner
• Confidence: 82% confidence

Finding

The skill description highlights convenience features like one-click deployment, rollback, and cleanup but does not clearly warn that some actions may be destructive, state-changing, or irreversible in practice. This can reduce informed consent and make users underestimate the operational impact of deployment, rollback, or job deletion.

Content

No source excerpt is available for this finding.

Vague Triggers

Medium

• Category: Not specified by scanner
• Confidence: 95% confidence

Finding

The trigger and clarification rules are broad enough to activate the deployment workflow for vague certificate-related requests, increasing the chance of the wrong skill taking control. In a skill that can modify cloud configuration, ambiguous activation raises the risk of unintended operations and unsafe context lock-in.

Content

No source excerpt is available for this finding.

Natural-Language Policy Violations

Medium

• Category: Not specified by scanner
• Confidence: 91% confidence

Finding

The file mandates an exact English response template for certain inputs, regardless of whether the user is interacting in Chinese or another language. This is a natural-language policy issue because it enforces a specific language without opt-in or offering a locale choice.

Content

No source excerpt is available for this finding.

Context-Inappropriate Capability

Medium

• Category: Not specified by scanner
• Confidence: 96% confidence

Finding

The skill includes software installation and self-update steps (curl download, bash execution, aliyun upgrade, plugin update) that go beyond certificate deployment and materially expand its authority. This creates a supply-chain and self-modification risk: an agent following the skill could alter its execution environment or run downloaded code before performing the stated task.

Content

No source excerpt is available for this finding.

Missing User Warnings

Medium

• Category: Not specified by scanner
• Confidence: 90% confidence

Finding

Creating and scheduling deployment jobs can immediately modify live cloud product certificate bindings, yet the reference does not prominently warn about production impact or require confirmation. In an agent setting, this can turn a seemingly informational request into a state-changing action that affects availability, trust chains, and customer-facing HTTPS behavior.

Content

No source excerpt is available for this finding.

Missing User Warnings

Medium

• Category: Not specified by scanner
• Confidence: 84% confidence

Finding

The rollback command alters deployed resource state but is documented without emphasizing that it performs another production change. Without strong operator acknowledgment, an agent could revert certificates on the wrong worker/resource and disrupt intended remediation or expose users to expired or mismatched certificates.

Content

No source excerpt is available for this finding.

Missing User Warnings

Medium

• Category: Not specified by scanner
• Confidence: 92% confidence

Finding

The delete job command is a destructive operation and is presented without an explicit warning or confirmation requirement. While deletion may not directly alter deployed certificates, it can remove auditability or interrupt operator workflows, making accidental use in an autonomous agent context unsafe.

Content

No source excerpt is available for this finding.

Description-Behavior Mismatch

Medium

• Category: Not specified by scanner
• Confidence: 94% confidence

Finding

The reference includes ALB infrastructure management actions such as creating listeners, server groups, adding backend servers, and routing rules, which materially exceed the stated scope of certificate deployment. In an agent skill, this scope expansion is dangerous because a user asking to deploy a certificate could trigger unintended changes to live traffic paths and backend exposure, not just TLS updates.

Content

No source excerpt is available for this finding.

Description-Behavior Mismatch

Medium

• Category: Not specified by scanner
• Confidence: 93% confidence

Finding

The documentation covers CDN domain creation and WAF domain onboarding, both of which are provisioning actions beyond simple certificate deployment. This broadens the agent's operational authority so a certificate task could lead to onboarding new public endpoints or changing request routing, increasing the risk of unintended production changes.

Session Persistence

Medium

• Category: Rogue Agent
• Confidence: 75% confidence

Finding

The guide explicitly instructs users to create and save long-lived AccessKey credentials, then later shows storage in ~/.aliyun/config.json and use through environment variables. In an agent-driven automation skill for certificate deployment, encouraging persistent static credentials increases the chance of credential theft, reuse, and over-privileged cloud access if the host, logs, or config files are exposed.

Troubleshooting

Missing User Warnings

Medium

• Category: Not specified by scanner
• Confidence: 91% confidence

Finding

The document recommends multiple broad *FullAccess system policies for certificate deployment workflows that can modify live CDN, WAF, OSS, and ALB infrastructure. In a skill intended for one-click or batch certificate deployment, presenting these powerful permissions without strong least-privilege guidance, scope restrictions, or explicit warnings increases the chance of overprivileged agent credentials being granted and then misused to alter production services.

Content

No source excerpt is available for this finding.

Context-Inappropriate Capability

Medium

• Category: Not specified by scanner
• Confidence: 89% confidence

Finding

The related-commands document includes aliyun cdn add-cdn-domain and status-polling for newly created domains, which expands the skill from certificate deployment into provisioning CDN infrastructure. In an agent context, documenting out-of-scope creation commands can cause the agent to take destructive or unauthorized actions beyond the user's intent, especially when the skill is activated for simple certificate deployment requests.

Content

No source excerpt is available for this finding.

Context-Inappropriate Capability

Medium

• Category: Not specified by scanner
• Confidence: 93% confidence

Finding

The ALB section documents commands for creating listeners, server groups, adding backend servers, and creating forwarding rules, which are full traffic-routing and infrastructure-modification capabilities rather than certificate deployment. In a deployment skill, exposing these commands increases the risk that an agent reconfigures production networking while attempting to install a certificate, potentially causing outage, misrouting, or unintended service exposure.

Content

No source excerpt is available for this finding.

Context-Inappropriate Capability

Medium

• Category: Not specified by scanner
• Confidence: 87% confidence

Finding

Including waf-openapi create-domain extends the skill into onboarding domains to WAF, which is a security-control and traffic-path change outside the stated purpose of deploying SSL certificates. In this skill context, that makes the finding more dangerous because a user asking to deploy a certificate may not expect domain enrollment into WAF, DNS/traffic changes, or associated policy side effects.
