Security audit

Rsyslog

Security checks for vulnerabilities and agentic risk

Overview

This is a coherent RSyslog reference skill that prints configuration examples; it has some production-safety caveats but no hidden execution, data theft, or persistence behavior.

Installers should treat this as a reference skill, not hardened production policy. Before copying examples into a real RSyslog deployment, prefer authenticated TLS with permitted peer names, constrain dynamic file paths, validate configurations with rsyslogd, and set queue and disk limits appropriate to the environment.

Vulnerability Patterns
  • Insecure Skill Coding PracticesFinds exploitable flaws such as hardcoded secrets or command injection
  • 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

Finding

Skill allows unbounded resource consumption (API calls, storage, compute). Without rate limits or quotas, a compromised or misbehaving agent can cause denial-of-service or cost overruns.
