Stack-based Buffer Overflow in Tenda AC18 /goform/SetDlnaCfg
CVE-2025-14993 is a stack-based buffer overflow vulnerability in the Tenda AC18 router, firmware version 15.03.05.05. The vulnerability exists in the sprintf function within the /goform/SetDlnaCfg HTTP request handler, where improper handling of the 'scanList' argument allows an attacker to overflow the stack buffer. This can be triggered by sending a specially crafted HTTP request with a maliciously long 'scanList' parameter, leading to memory corruption and potential arbitrary code execution.
