Full Analysis
  • [COMMAND_EXECUTION]: Potential SPL injection vulnerability in scripts/agent.py. The script constructs search queries using f-strings and direct string concatenation with values provided via command-line arguments. Specifically, the build_incident_timeline function joins user-provided host and user names with " OR " and wraps them in double quotes. Since these inputs are not sanitized or escaped, a user could provide a crafted host or username containing a closing quote and SPL command pipe (e.g., WKSTN-042" | delete | search host=") to execute unauthorized actions within the Splunk environment.
  • [INDIRECT_PROMPT_INJECTION]: The skill processes untrusted security logs that could contain malicious instructions designed to mislead an agent or analyst.
  • Ingestion points: The agent script scripts/agent.py ingests data from multiple Splunk indexes including windows, sysmon, proxy, and firewall.
  • Boundary markers: The SPL queries in SKILL.md and scripts/agent.py use eval to create summaries but do not implement boundary delimiters to separate the log content from the analysis context.
  • Capability inventory: The skill has the ability to query Splunk APIs and generate reports based on the retrieved data.
  • Sanitization: There is no evidence of sanitization, filtering, or escaping of log content before it is interpolated into the final report structure.
