Summary

This vulnerability enables network-adjacent attackers to execute arbitrary code on affected installations of D-Link DIR-1935 routers. While authentication is usually required, it can be bypassed due to a flaw in the authentication mechanism. The issue occurs during the handling of SetStaticRouteIPv4Settings requests within the web management portal, where user-supplied strings are not properly validated before executing system calls. This oversight allows an attacker to execute code with root privileges, potentially compromising the entire system.

Affected Version(s)
