CVE-2026-6136 Details
Description
A security vulnerability has been detected in Tenda F451 1.0.0.7_cn_svn7958. Impacted is the function frmL7ImForm of the file /goform/L7Im. The manipulation of the argument page leads to stack-based buffer overflow. It is possible to initiate the attack remotely. The exploit has been disclosed publicly and may be used.
A stack-based buffer overflow vulnerability has been identified in the Tenda F451 router, specifically in the firmware version 1.0.0.7_cn_svn7958. The issue arises in the 'frmL7ImForm' function within the '/goform/L7Im' file, where user-supplied data in the 'page' parameter is processed by the 'sprintf' function 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.
