Sophos Web Protection Appliance sblistpack Command Injection Exploit

The /opt/ws/bin/sblistpack Perl script in Sophos Web Protection Appliance, which can be reached from the web interface, is vulnerable to OS command injection because its get_referers() function does not escape the first argument of the script before using it within a string that will be executed as a command by using backticks. A remote unauthenticated attacker can exploit this vulnerability to execute arbitrary code in the affected appliance with the privileges of the "spiderman" operating system user. A second vulnerability in the Sophos Web Protection Appliance (an OS command injection in the /opt/cma/bin/clear_keys.pl script, which can be executed by the "spiderman" user with the sudo command without password) allows an attacker who successfully compromised the appliance to escalate privileges from "spiderman" to root.
