Exploit code surfaces for CA vulnerability

Companies that use Computer Associates storage software are being warned to update their systems after exploit code surfaced for a recently-patched vulnerability. 

The US Computer Emergency Response Team (US-Cert) reported that exploit code has been posted for a vulnerability in the CA Brightstor ARCserve Backup Media application. The exploit targets the 'mediasvr' component in the software. 

SecurityFocus said that the vulnerability is known to exist in at least nine of CA's server security and backup applications. 

Users can mitigate the vulnerability by installing a vendor patch released in January, according to SecurityFocus.

US-Cert does not list a solution for the vulnerability and advises administrators to restrict the use of remote procedure call commands.

SecurityFocus said that a successful exploit could offer system-level access to the target machine with the ability to remotely execute code. If the exploit attempt fails, a denial of service crash could be triggered.
