Sophos Web Appliance Privilege Escalation and Remote Code Execution Vulnerability

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Sophos Web Appliance. Authentication is required to exploit this vulnerability. The specific flaws exist within the change_password and netinterface functions of the web appliance. The first flaw will allow for an unprivileged user to change the admin’s password and a remote code execution vulnerability exists when updating the network interface. This allows for an attacker to execute under root privileges.
