CVE-2026-3732 Details
Description
A security vulnerability has been detected in Tenda F453 1.0.0.3. This affects the function strcpy of the file /goform/exeCommand. The manipulation of the argument cmdinput 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 F453 router, specifically in version 1.0.0.3. The issue arises in the 'httpd' component, within the 'formexeCommand' function of the '/goform/exeCommand' file. The vulnerability is triggered by manipulating the 'cmdinput' parameter, which is passed to the 'strcpy' 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.
