CVE-2025-12273 Details
Description
A weakness has been identified in Tenda CH22 1.0.0.1. Affected is the function fromwebExcptypemanFilter of the file /goform/webExcptypemanFilter. Executing a manipulation of the argument page can lead to buffer overflow. The attack may be launched remotely. The exploit has been made available to the public and could be used for attacks.
A critical buffer overflow vulnerability has been identified in the Tenda CH22 router, specifically in version 1.0.0.1. The issue arises in the webExcptypemanFilter endpoint, where the fromwebExcptypemanFilter function processes the user-controlled page parameter using sprintf. This method writes data into a fixed-size buffer without proper length checks, allowing input larger than 256 bytes to overwrite adjacent memory. Such exploitation can lead to application crashes, memory corruption, or arbitrary code execution, posing significant risks to the device's stability, data confidentiality, and overall security.
