Symantec Web Gateway Shell Command Injection Remote Code Execution Vulnerability

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Symantec Web Gateway. Authentication is not required to exploit this vulnerability. The specific flaw exists due to insufficiently filtered user-supplied data used in a call to exec() in multiple script pages. The affected scripts are located in ‘/spywall/ipchange.php’ and ‘network.php’. There is also a flaw in ‘/spywall/download_file.php’ that allows unauthenticated users to download and delete any file on the server.
