Cisco NXOS Hardening

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed Cisco NX-OS configuration generator that calls an external API but does not install code, persist itself, or directly modify devices.

Before installing, be comfortable sending hardening selections and request metadata to the listed third-party API. Avoid including real secrets, credentials, internal IPs, or sensitive topology details unless you have reviewed the provider's privacy and retention practices.

A.I.G

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

Missing User Warnings

Not specified by scanner
Confidence
90% confidence
Finding

The skill explicitly collects sessionId, userId, and timestamp metadata but provides no privacy notice, data minimization guidance, retention policy, or handling constraints. In a security-focused tool, collecting correlatable identifiers without documented safeguards increases the risk of unnecessary tracking, exposure in logs, and downstream privacy/compliance issues.

Data Exfiltration
Confidence
50% confidence
Finding

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