CVE-2025-12271 Details
Description
A vulnerability was identified in Tenda CH22 1.0.0.1. This affects the function fromRouteStatic of the file /goform/RouteStatic. Such manipulation of the argument page leads to buffer overflow. The attack can be launched remotely. The exploit is publicly available and might be used.
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 RouteStatic endpoint, where the fromRouteStatic 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 memory manipulation can lead to application crashes, memory corruption, or arbitrary code execution. The vulnerability poses significant risks to device stability, data confidentiality, and overall system security, necessitating immediate attention to prevent exploitation.
