Cisco Secure Web Appliance Elevation of Privilege Vulnerability.
A vulnerability in the log subscription subsystem of Cisco AsyncOS for the Cisco Secure Web Appliance (formerly Web Security Appliance) could allow an authenticated, local attacker to perform command injection and elevate privileges to root.
In addition, it is due to insufficient validation of user-supplied input for the web interface and CLI.
An attacker could exploit this vulnerability by authenticating to the affected device and injecting scripting commands in the scope of the log subscription subsystem.
However, a successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system and elevate privileges to root.
