Advisory Details

This vulnerability allows remote attackers to execute arbitrary code on affected installations of BEC Technologies Multiple Routers. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed.

The specific flaw exists within the management interface, which listens on TCP port 22 by default. The issue results from the lack of proper validation of a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute code in the context of the device.
