Title

Authenticated Stack-Based Buffer Overflow in TP-Link TL-WR841N Web Interface

Summary

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. Successful exploitation results in a denial-of-service condition, causing the device to crash and automatically reboot.

Severity

6.8 (Medium)
