  • Look for unauthenticated GET requests to /fosagent/repl/download-snapshot with a 'name' parameter containing path traversal sequences (e.g., ..\..\) in HTTP logs.
  • Response body containing 'bit app support', 'fonts', and 'extensions' simultaneously indicates successful exploitation (win.ini retrieval).
  • Shodan/FOFA queries for exposed ManageEngine ServiceDesk instances: http.title:"ManageEngine" or title="manageengine".
  • The vulnerability is exploitable without authentication; monitor for requests to /fosagent/repl/download-snapshot from unauthenticated sessions.
  • ·The vulnerability affects ManageEngine ServiceDesk up to and including version 9.3.9328; no fix was available as of that version according to the advisory.
  • ·The Nuclei template uses stop-at-first-match across two exploit paths (download-file and download-snapshot); both endpoints should be monitored independently.
