A stack-based buffer overflow vulnerability has been identified in the Tenda FH451 router, specifically in version 1.0.0.9. The issue arises in the 'formQuickIndex' function within the '/goform/QuickIndex' file. The vulnerability is triggered by manipulating the 'mit_linktype' and 'PPPOEPassword' parameters. When 'mit_linktype' is set to 2, the lack of length validation allows for a buffer overflow, which could be exploited remotely. This vulnerability is classified as critical, with the potential for denial-of-service or remote code execution impacts.
