Vulnerable Systems:
 * Sophos Web Appliance

The Sophos Web Appliance (version is vulnerable to two Remote Command Injection vulnerabilities affecting its web administrative interface. These vulnerabilities occur in the MgrReport.php (/controllers/MgrReport.php) component responsible for blocking and unblocking IP addresses from accessing the device. The device doesn’t properly escape the information passed in the variables ‘unblockip’ and ‘blockip’ before calling the shell_exec() function which allows for system commands to be injected into the device. The code erroneously suggests that the information handled is protected by utilizing the variable name ‘escapedips’ – however this was not the case. The Sophos ID is NSWA-1258.
