The APISiteScopeImpl SOAP service in HP SiteScope 10.1x and 11.x before 11.22 allows remote attackers to bypass authentication and execute arbitrary code via a direct request to the issueSiebelCmd method, aka ZDI-CAN-1765.

  • Detect unauthenticated POST requests to the APISiteScopeImpl SOAP endpoint targeting the issueSiebelCmd method, which allows arbitrary command execution without credentials.
  • Look for HTTP 500 responses containing the string 'Cmd Error: User and Password must be specified' as a fingerprint of a vulnerable HP SiteScope instance being probed.
  • Inspect SOAP requests for the namespace 'http://Api.freshtech.COM' and the element 'api:issueSiebelCmd' — these are specific to exploit payloads targeting this vulnerability.
  • Server banner matching /Apache-Coyote/ can be used to fingerprint the target as HP SiteScope prior to exploitation.
  • ·The default TARGETURI path is '/SiteScope/' but may vary in non-default deployments; detection rules should account for alternate base paths.
  • ·The exploit targets both Windows (x86 VBS cmdstager via cmd.exe) and Linux (CMD arch via perl/python/bash-tcp/gawk/openssl payloads); detection should cover both platform variants.
  • ·On Linux, the payload avoids characters 0x20 (space), 0x22 ("), 0x27 ('), and 0x3c (<); signatures relying on these characters in the payload body may miss Linux-targeted attacks.
