Description from ZDI advisory: This vulnerability allows attackers to execute arbitrary code on vulnerable installations of Computer Associates eTrust Secure Content Manager. Authentication is not required to exploit this vulnerability.

The specific flaw exists in the eTrust Common Services Transport (ECSQdmn.exe) running on port 1882.
