The get_referers function in /opt/ws/bin/sblistpack in Sophos Web Appliance before 3.7.9.1 and 3.8 before 3.8.1.1 allows remote attackers to execute arbitrary commands via shell metacharacters in the domain parameter to end-user/index.php.

Cross-site request forgery (CSRF) vulnerability in the web framework on Cisco IronPort Web Security Appliance (WSA) devices, Email Security Appliance (ESA) devices, and Content Security Management Appliance (SMA) devices allows remote attackers to hijack the authentication of arbitrary users, aka Bug IDs CSCuh70263, CSCuh70323, and CSCuh26634.
