  • →Detect POST login attempts using the hardcoded hidden account 'IntegrationUser' with password 'plugin' to /jsp/Login.do with authType=localUserLogin ↗
  • →Alert on HTTP POST requests to /api/json/admin/SubmitQuery containing SQL keywords INSERT, lo_create, lo_export, or lo_unlink, especially with comment-based keyword bypass (INSERT/**/INTO) ↗
  • →Monitor for WAR file creation under the Tomcat webapps directory (tomcat/webapps/*.war) originating from the OpManager PostgreSQL process, indicating lo_export-based payload drop ↗
  • →Detect the API key extraction pattern in HTTP responses: window.OPM.apiKey = "[a-z0-9]+" — successful login by IntegrationUser will return this key, which is then used for subsequent SQL abuse ↗
  • →Flag HTTP GET requests to /LoginPage.do followed immediately by a POST to /jsp/Login.do with domainName=NULL and authType=localUserLogin from the same source IP as a potential exploitation attempt ↗
  • ·The hardcoded 'IntegrationUser' account cannot be reset or removed through the OpManager user interface, meaning patching or upgrading is the only remediation; detection must account for this account being permanently present in affected builds. ↗
  • ·The exploit has been confirmed working on OpManager v11.0 and v11.4–v11.6 for Windows; detections should be scoped to these versions but the hardcoded credential may exist in earlier builds as well (NVD states build 11600 and earlier). ↗
