CyberRota Analysis
AI-GeneratedThe Tenda CP3 V3.0 firmware version V31.1.9.91 is vulnerable due to improper validation of the Content-Length header in RTSP requests, leading to a denial-of-service condition when an attacker sends a specially crafted request. This vulnerability allows unauthenticated remote attackers to cause the device's TCP connection to enter a persistent body-awaiting state, resulting in a resource leak and rendering the connection permanently non-functional. Organizations using this firmware should prioritize patching to mitigate the risk of exploitation and ensure service availability.

Original NVD Description
Tenda CP3 V3.0 firmware V31.1.9.91 does not validate the Content-Length header field in RTSP requests (including DESCRIBE, SETUP, and PLAY methods). When a request carrying a Content-Length header is received without a corresponding message body, the RTSP parser enters a persistent body-awaiting state, causing the affected TCP connection to become permanently non-functional. The device does not actively close the connection, resulting in a TCP resource leak. This issue can be exploited by an unauthenticated remote attacker to cause a denial-of-service condition.
