  • Authentication bypass is triggered by appending a semicolon (;) to the end of a .jspa action URL path, bypassing Jira Seraph's authentication check. Look for GET requests to .jspa endpoints ending with a trailing semicolon.
  • A successful exploit returns HTTP 200 with the string 'General Insight Configuration' in the response body without authentication.
  • Two probe paths are used for detection: InsightPluginShowGeneralConfiguration.jspa; and secure/WBSGanttManageScheduleJobAction.jspa; — monitor for unauthenticated access returning 200 on either.
  • ·Affected versions for Jira Server and Data Center: before 8.13.18, 8.14.0–8.20.5, and 8.21.0–8.21.x (before 8.22.0). Affected versions for Jira Service Management Server and Data Center: before 4.13.18, 4.14.0–4.20.5, and 4.21.0–4.21.x (before 4.22.0). Detection probes are only valid against these unpatched versions.
  • ·The nuclei template uses stop-at-first-match, meaning only one of the two probe URLs will be tested per scan run. Both paths should be tested independently for comprehensive coverage.
