🔍 How to Verify

Check if Vulnerable:

Check if HaloBot is installed and if plugins/html_renderer/index.js exists. Verify commit hash is 026b01d4a896d93eaaf9d5163a287dc9f267515b or earlier.

Check Version:

git log --oneline -1

Verify Fix Applied:

Confirm html_renderer plugin is removed/disabled and no longer accessible via the Inter-plugin API.

📡 Detection & Monitoring

Log Indicators:

  • Unusual API calls to html_renderer plugin
  • Suspicious process execution from HaloBot context
  • Error logs related to html_renderer manipulation

Network Indicators:

  • Unexpected outbound connections from HaloBot host
  • Traffic to/from HaloBot on unusual ports

SIEM Query:

source="halobot.log" AND "html_renderer" AND ("action" OR "exec" OR "eval")
