## Technical details

A stack-based buffer overflow vulnerability exists in the Tenda BE12 Pro router (firmware version 16.03.66.23) within the '/goform/DhcpListClient' endpoint. The root cause is the unsafe use of the 'sprintf' function in the 'fromDhcpListClient' function, which processes the user-controlled 'page' parameter without adequate length validation. The destination buffer is fixed at 256 bytes, and providing a larger input allows an attacker to overwrite adjacent stack memory. While the advisory suggests the attack can be initiated remotely and provides a proof-of-concept that does not include authentication headers, the CVSS vector indicates low privileges (PR:L) may be required. Successful exploitation can lead to a Denial of Service (DoS) of the web management interface or arbitrary code execution.
