SWG OS command Injection
Details
Symantec was notified of an OS command injection vulnerability in PHP script which impacts the SWG management console. The results of successful exploitation could potentially range from unauthorized disclosure of sensitive data to possible unauthorized access to the Symantec Web Gateway Appliance.
Unauthenticated arbitrary commands can potentially be injected into existing application scripts accessible though the SWG console's interface if the attacker already has some level of privileged access. This issue is of limited scope and impact and has been addressed in SWG 5.2.2.
In a normal installation, the Symantec Web Gateway management interface should not be externally accessible from the network environment and would require access to the network either by an authorized network user or an external attacker able to leverage network access.
Symantec Response
Symantec engineers have verified these issues and have addressed them in SWG 5.2.2. Symantec continues to review related functionality in order to further enhance the overall security of the Symantec Web Gateway product.
Symantec has released Symantec Web Gateway 5.2.2, currently available to customers through normal support locations. Customers should ensure they are on this latest release. To confirm customers are running the latest updates, check the “Current Software Version -> Current Version” on theAdministration -> Updatespage. Alternatively, customers can click the “Check for Updates” button on theAdministration -> Updates page to verify that they are running the latest software version.
