Vulnerability Details

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 HTTP Gateway service icihttp.exe running on port 8080. When issuing a request for a FTP service the process tries to decorate the contents of the transaction. In this particular case by specifying a overly long response to a LIST command a stack buffer can be overflowed. Successful exploitation can lead to complete system compromise under the SYSTEM context.
