A stack-based buffer overflow vulnerability has been identified in the Tenda F451 router, specifically in version 1.0.0.7. The issue arises in the formWrlExtraSet function within the file /goform/WrlExtraSet. The vulnerability is triggered by manipulating the GO parameter, which is passed to a subroutine without proper length validation. This oversight allows for the overflow of a stack-based buffer, potentially leading to arbitrary code execution or a denial-of-service condition. The vulnerability can be exploited remotely, and a public proof-of-concept exploit is available.
