## Beschreibung

An authenticated stack-based buffer overflow vulnerability exists in the web management interface of TP-Link TL-WR841N v14.  A remote authenticated attacker can send crafted HTTP requests to cause the embedded web server to overflow a stack buffer, resulting in a crash of the affected process.
