CVE-2022-26987Public exploit

Local code execution via unchecked stack copy

Published May 10, 2022 · Updated Jul 9, 2026

Stack overflow in TP-Link TL-WDR7660, Mercury D196G, and Fast FAC1900R routers allows local users to execute arbitrary code. MmtAtePrase accepts data from UDP port 1060 and passes prefixed input through the strcpy-like spliter routine into a fixed stack buffer without checking its length. Local access to the UDP service is required, and successful control-flow corruption executes attacker-supplied code in the router firmware context.
