CVE-2025-15215Network attack vector

Authenticated memory corruption via crafted PPTP list

Published Dec 30, 2025 · Updated Dec 30, 2025

A buffer overflow in Tenda AC10U 15.03.06.48 and 15.03.06.49 allows remote authenticated users to corrupt memory via an HTTP POST. The formSetPPTPUserList function handling /goform/setPptpUserList processes a crafted list argument without enforcing the destination buffer's bounds. An authenticated network session is required; the published record does not specify whether exploitation causes a crash or code execution.
