  • Exploit targets HTTP POST requests to the /Operajserv/webarchive/FileReceiver endpoint with a filename parameter pointing to a Windows path under \MICROS\, combined with jndiname and username parameters — all three must be present.
  • Exploit requests use multipart/form-data content type; inspect for this alongside the malicious URI pattern.
  • The filename parameter value matches a Windows absolute path pattern (drive letter + colon + backslash + MICROS + backslash), indicating a path traversal/file write attempt on the OPERA 5 server.
  • External reference for full exploit analysis and PoC details available at blog.assetnote.io.
  • ·The Emerging Threats rule (sid:2045307) is marked with confidence:Low — tune carefully to avoid false positives before deploying in blocking mode.
  • ·The vulnerability is rated High complexity (AC:H) and requires high privileges (PR:H), meaning exploitation is not trivial and requires a pre-authenticated, privileged attacker over the network.
  • ·Scope change (S:C) is indicated — successful exploitation can impact systems beyond the directly vulnerable Oracle Hospitality OPERA 5 Property Services instance.
  • ·Only version 5.6 of Oracle Hospitality OPERA 5 Property Services is confirmed affected; scope detection rules to relevant assets.
