Symantec Web Gateway Arbitrary PHP File Upload Remote Code Execution and Multiple XSS Vulnerabilities
|[+]||Product:||Symantec Web Gateway|
|[+]||Versions affected:||software before 5.2.2 DB 188.8.131.527|
Symantec Web Gateway (SWG) appliances with software before 5.2.2 DB 184.108.40.2067 allow remote authenticated users to execute arbitrary code by uploading a file with a safe extension and content type in the management console, and then leveraging an improper Sudo configuration to make this a setuid-root file to escalate privileges. In addition, multiple cross-site scripting (XSS) vulnerabilities exist in PHP scripts in the management console which allow remote attackers to inject arbitrary web script or HTML. Attackers can chain these vulnerabilities to craft a pre-auth XSS-to-root exploit with minimal user interaction. The results of successful exploitation could potentially range from a user with authorized but lower-privileged access to the management console gaining unauthorized access to sensitive data or another user’s account to unauthorized manipulation of the console and underlying operating system.
