Full Analysis
- [COMMAND_EXECUTION]: The script
scripts/agent.pyusessubprocess.runto execute thebinwalkutility for firmware extraction. The command is executed using a list of arguments, which mitigates shell injection risks, but grants the skill the ability to run external system binaries. - [PROMPT_INJECTION]: The skill is susceptible to indirect prompt injection due to the way it processes untrusted data. 1. Ingestion points: The skill ingests external PLC firmware images and proprietary project files (e.g., Siemens TIA Portal archives and Rockwell Studio 5000 ACD files) as seen in
SKILL.mdandscripts/agent.py. 2. Boundary markers: There are no explicit boundary markers or instructions to the agent to disregard potential control strings embedded within the processed binary files. 3. Capability inventory: The skill possesses capabilities including system command execution viasubprocess.run(scripts/agent.py) and raw network socket communication for Modbus protocol testing (SKILL.md). 4. Sanitization: Content from extracted files is read and processed using regex and printed to the console (truncated) without sanitization to prevent potential instruction injection into the LLM context.
