Symantec Web Gateway Multiple Vulnerabilities

Multiple vulnerabilities have been identified in Symantec Web Gateway. which can be exploited by remote user conduct cross-site scripting attacks, conduct cross-site request forgery attacks, inject SQL commands and compromise a vulnerable system.

1. A remote user with access to the Symantec Web Gateway (SWG) console interface can execute commands with elevated privileges.
2. The software does not properly filter HTML code from user-supplied input before displaying the input. A remote user can cause arbitrary scripting code to be executed by the target user's browser. The code will originate from the site running the Symantec Web Gateway software and will run in the security context of that site. As a result, the code will be able to access the target user's cookies (including authentication cookies), if any, associated with the site, access data recently submitted by the target user via web form to the site, or take actions on the site acting as the target user.
3. A remote user can conduct cross-site request forgery attacks to take actions on the target site acting as the target user.
4. A remote authenticated user can supply a specially crafted parameter value to execute SQL commands on the underlying database.
5. The sudoer file configuration allows a remote authenticated user with sudo authorization to run unauthorized commands.
6. A remote user with access to the SWG console can exploit a Radius authentication flaw to run arbitrary code on the target system.
