ZDI-CAN-16151: D-Link DIR-1935 SetVirtualServerSettings VirtualServerInfo Command Injection Remote Code Execution Vulnerability
This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of D-Link DIR-1935 routers. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed. The specific flaw exists within the handling of SetVirtualServerSettings requests to the web management portal. When parsing subelements within the VirtualServerInfo element, the process does not properly validate 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.
