Known benign triggers

  • Similar to CVE-2023-35078, the path for exploitation indicates that status=200 is required for successful exploitation of the vulnerability. False positives may be present if status=200 is removed from the search. If it is removed,then the search also alert on status=301 and status=404 which indicates unsuccessful exploitation attempts. Analysts may find it useful to hunt for these status codes as well, but it is likely to produce a significant number of alerts as this is a widespread vulnerability.
