Symantec Web Gateway upload_file() Remote Code Execution (SYM12-006) (intrusive check)

high Nessus Plugin ID 59210

Language:

Synopsis

A web security application hosted on the remote web server has a remote code execution vulnerability.

Description

The remote web server is hosting a version of Symantec Web Gateway with a code execution vulnerability. The upload_file() function of util_functions.php allows PHP files to be uploaded to a directory where the web server can execute them. This function is used by multiple PHP scripts that can be requested without authentication. A remote, unauthenticated attacker could exploit this to execute arbitrary code.
Achieving root command execution is trivial.

Solution

Upgrade to Symantec Web Gateway 5.0.3 or later.
