Alibaba Cloud Media ICE

Security checks for vulnerabilities and agentic risk

Overview

The skill is a coherent Alibaba Cloud ICE management helper with disclosed API discovery, credential expectations, cloud operations, and local evidence output; users should treat saved evidence as potentially sensitive.

Install only if you intend to let an agent help with Alibaba Cloud ICE. Use least-privilege RAM or STS credentials, confirm region and workflow scope before mutations, and review files saved under output/aliyun-ice-manage/ for secrets, signed URLs, customer data, and sensitive media metadata before keeping or sharing them.

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs

Findings (10)

Tainted flow: 'timeout' from os.getenv (line 30, credential/environment) → urllib.request.urlopen (network output)

Critical
Category
Data Flow
Confidence
90% confidence
Finding

Credentials or environment variables flow to a network sink. This is a high-confidence indicator of credential exfiltration.

def fetch_json(url: str, timeout: int) -> dict:

High
Category
MCP Tool Poisoning
Confidence
96% confidence
Finding

The documented purpose presents the skill as managing ICE workflows and jobs, but the observable behavior described here is primarily API metadata discovery and local documentation generation. This mismatch can mislead operators about what the skill actually does, weakening security review and enabling unexpected network access and file creation under the guise of routine cloud-management automation.

Undeclared Tool Scope

Medium
Category
MCP Least Privilege
Confidence
94% confidence
Finding

The skill uses capabilities associated with environment access, filesystem writes, and network access, but it does not declare any tool restrictions or permissions scope. That creates an authorization ambiguity where a caller or agent may execute broader actions than expected, increasing the risk of credential exposure, unintended outbound requests, or local persistence without explicit review.

Session Persistence

Medium
Category
Rogue Agent
Confidence
60% confidence
Finding

Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.

Validation

bash

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
94% confidence
Finding

The template instructs users to save full request payloads and API responses, plus workflow IDs, job IDs, and output object paths, without any warning to avoid secrets, tokens, signed URLs, internal identifiers, or customer media metadata. In a cloud media workflow context, these artifacts can contain sensitive operational data and may be retained insecurely or shared broadly as troubleshooting evidence.

External Transmission

Category
Data Exfiltration
Confidence

Finding

Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.
