Vulnerability Details
This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of D-Link DIR-2150 routers. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed.

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 root.
