Description
A security flaw has been discovered in Tenda i12 1.0.0.6(2204). Impacted is the function vos_strcpy of the file /goform/exeCommand. The manipulation of the argument cmdinput results in stack-based buffer overflow. The attack can be launched remotely. The exploit has been released to the public and may be used for attacks.
A stack-based buffer overflow vulnerability has been identified in the Tenda i12 router, specifically in version 1.0.0.6(2204). The issue arises in the exeCommand function, where the cmdinput parameter is passed to the vos_strcpy function without proper length validation. This lack of checks allows for the overflow of stack-based buffers, potentially leading to arbitrary code execution or a denial-of-service condition. The vulnerability can be exploited remotely, and a public exploit is available.
