Vulnerability from variot

admin_messages.php in the management console on Symantec Web Gateway (SWG) appliances with software before 5.2.2 DB 5.0.0.1277 allows remote authenticated users to execute arbitrary code by uploading a file with a safe extension and content type, and then leveraging an improper Sudo configuration to make this a setuid-root file. Authentication is required to exploit this vulnerability, however it can be bypassed via reflected cross-site scripting.The specific flaw exists within the admin_messages.php file which relies on mimetypes and file extensions to block potentially dangerous file uploads. An attacker can exploit this condition to upload arbitrary files as the apache user. Due to loose sudo restrictions, an attacker can add the setuid attribute and execute arbitrary code under the context of root. This may facilitate an arbitrary command execution with elevated privileges; other attacks are also possible. 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. There is a security vulnerability in the admin_messages.php script in the management console of SWG devices using software versions earlier than 5.2.2 DB 5.0.0.1277
