Description

The

TL-WR940N v6 router contains a vulnerability in its RTSP connection tracking

module that can lead to a stack-based buffer overflow. The issue occurs when a

LAN client initiates a connection to a malicious RTSP server controlled by an

attacker. A specially crafted RTSP message may trigger improper memory handling

within the kernel module

Successful

exploitation of this vulnerability may result in a denial-of-service (DoS)

condition or allow remote code execution (RCE), potentially leading to full

compromise of the device. This vulnerability can be exploited by an

unauthenticated attacker under the device's default configuration.
