Who is Vulnerable?
Vulnerability Description CA eTrust Secure Content Manager (SCM) is a gateway product for Windows platform that secures, monitors, filters and blocks potential threats from messaging and Web traffic. It provides protection against malware, spam, phishing, P2P file sharing and prevents access to known spyware sites. All CA SCM installations can be administered through a central management console. There exists a buffer overflow vulnerability in CA eTrust Secure Content Manager. The vulnerability is due to insufficient bounds checking on certain FTP responses. A remote unauthenticated attacker can exploit this vulnerability by sending a specially crafted FTP PASV response to the target server, potentially causing arbitrary code injection and execution with the privileges of the affected process, normally System. If an attack results in successful code injection and its subsequent execution, the behaviour of the target host will depend on the malicious code being executed. Note that any code execution will be within the security context of the affected service, normally System. If the attack is not successful in code injection and execution, the icihttp.exe server process will terminate due to memory corruption, causing a denial of service condition.
