A
stack-based out-of-bounds write vulnerability exists in the login request
handling functionality of the administrative web interface of TP-Link TL-MR6400 v7 routers. An unauthenticated adjacent attacker can trigger the vulnerability
by sending a specially crafted malformed HTTP request.
Successful
exploitation may cause the web service process to crash, resulting in a
denial-of-service condition and temporary loss of access to the router's web
management interface.
