Remote Command Injection Vulnerability in Sophos Web Appliance

CVE-2016-9553

Summary

The Sophos Web Appliance is affected by a Remote Command Injection vulnerability within its web administrative interface. Specifically, two vulnerabilities exist in the MgrReport.php component, which handles the blocking and unblocking of IP addresses. The system fails to properly sanitize user inputs from the 'unblockip' and 'blockip' variables before executing them via the shell_exec() function. This oversight allows attackers to inject arbitrary commands into the system. Although the variable name 'escapedips' implies some level of protection, the actual implementation is flawed, exposing the device to exploitation.
