Symantec Web Gateway (SWG) Appliance management console is susceptible to both local and remote access cross-site scripting (XSS) and local access SQL injection (sqli) vulnerabilities. Successful exploitation may result in an authorized user gaining unauthorized access to files on the management console or possibility being able to manipulate the backend data base. There is also potential for remote hijacking of an authorized user session with associated privileges.

Cross-Site Scripting
Details
Symantec was notified of security issues impacting the Symantec Web Gateway management console. The results of successful exploitation could potentially range from a user with authorized access to the management console gaining unauthorized access to sensitive data or another user's account to unauthorized manipulation of the backend application database.
Local access SQL injection issues were identified allowing an authenticated Symantec Web Gateway user to make unauthorized database queries. Successful targeting could potentially result in unauthorized disclosure of privileged information and/or possible unauthorized manipulation of the backend database.
Symantec Web Gateway in certain cases does not properly validate/sanitize external input allowing the potential of cross-site scripting attempts by both authorized but non-privileged and in some instances unauthorized individuals. Successful targeting of these issues could result in unauthorized access by an authorized but unprivileged user or potentially allowing an unauthorized individual to hijack an authorized Symantec Web Gateway user session with associated privileges.
