Security audit

Firewalld

Security checks for vulnerabilities and agentic risk

Overview

This skill is a low-quality, generic firewalld reference stub, but it does not show harmful behavior or sensitive access.

Install only if you are comfortable with a basic canned-reference helper. It should not be relied on as an accurate firewalld guide without checking official firewalld documentation, but the inspected package does not show credential access, system changes, persistence, or exfiltration.

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

MCP Tool Poisoning

Finding

The declared description suggests a tool specifically for working with firewalld in sysops contexts. The code, however, is just a menu-driven text emitter with canned sections like intro, quickstart, security, and migration. The text is generic and template-like, with almost no substantive firewalld-specific commands, concepts, syntax, zones, services, rich rules, runtime vs permanent configuration, or troubleshooting details one would expect from an actual firewalld reference tool. While it is superficially labeled 'firewalld,' its actual primary behavior is serving generic documentation placeholders, so the description materially overstates its purpose and specificity.

Finding

Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.

Intent-Code Divergence

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The top-level comment explicitly describes the script as a firewalld reference tool, and the help banner repeats that framing, but the emitted content does not substantively document firewalld itself. This is an intent-code divergence because the documentation claims a specialized reference purpose that the implementation does not fulfill.

Description-Behavior Mismatch

Medium
Category
Not specified by scanner
Confidence
97% confidence
Finding

Across the command handlers, the script prints broad, template-style operational advice about installation, security, migration, performance, and debugging without providing firewalld-specific concepts, commands, configuration details, or semantics. This does not match the manifest's stated purpose of being a 'Firewalld reference tool' because the implemented behavior is a generic documentation stub rather than a firewalld reference.
