Description
A vulnerability has been found in Tenda A18 Pro 02.03.02.28. Impacted is the function fromSetIpMacBind of the file /goform/SetIpMacBind. Such manipulation of the argument list leads to stack-based buffer overflow. The attack can be executed remotely. The exploit has been disclosed to the public and may be used.
A stack-based buffer overflow vulnerability has been identified in the Tenda A18 Pro router, specifically in the firmware version 02.03.02.28. The issue arises in the IP-MAC binding configuration endpoint '/goform/SetIpMacBind', within the 'fromSetIpMacBind' function. This function processes the 'list' parameter, which contains binding rules, but fails to validate the input length before copying it into a fixed-size stack buffer. The vulnerability can be exploited remotely, leading to potential unauthorized code execution.
