Summary

This vulnerability in D-Link DIR-1935 routers allows network-adjacent attackers to execute arbitrary code through a flaw in the authentication mechanism. Attackers can exploit the vulnerability by sending malicious SetStaticRouteIPv4Settings requests to the web management portal. The process fails to validate the length of the user-supplied NetMask data, leading to a buffer overflow in a fixed-length stack-based buffer. As a result, an attacker could potentially execute code with root privileges on the affected system.

Affected Version(s)

DIR-1935 1.03
