CVE-2025-15217Public exploitNetwork attack vector

Authenticated memory corruption via unchecked list argument

Published Dec 30, 2025 · Updated Dec 30, 2025

Buffer overflow in the HTTP POST handler in Tenda AC23 16.03.07.52 allows remote authenticated users to corrupt memory via a crafted list. The formSetPPTPUserList function processes the untrusted list argument without enforcing the destination buffer's bounds. Low-privileged management access is required, and published material does not establish whether exploitation ends in a crash or controlled code execution.
