CVE-2026-6137 Details
Description
A vulnerability was detected in Tenda F451 1.0.0.7_cn_svn7958. The affected element is the function fromAdvSetWan of the file /goform/AdvSetWan. The manipulation of the argument wanmode/PPPOEPassword results in stack-based buffer overflow. It is possible to launch the attack remotely. The exploit is now public and may be used.
A stack-based buffer overflow vulnerability has been identified in the Tenda F451 router, specifically in version 1.0.0.7_cn_svn7958. The issue arises in the 'fromAdvSetWan' function within the '/goform/AdvSetWan' file, where user-provided parameters 'wanmode' and 'PPPOEPassword' are not properly validated. When 'wanmode' is set to 2, this lack of length checking allows for the overflow to occur, potentially leading to arbitrary code execution or a denial-of-service condition. This vulnerability can be exploited remotely, and a public proof-of-concept exploit is available.
