CVE-2022-25450Network attack vector

Unauthenticated memory corruption via crafted list parameter

Published Mar 18, 2022 · Updated Aug 3, 2024

Stack overflow in Tenda AC6 firmware 15.03.05.09_multi allows remote attackers to corrupt memory through a crafted list parameter. SetVirtualServerCfg places the list value into stack storage, but the public record does not identify the copy operation or omitted bounds check. Network access to the vulnerable handler is required; a crash is consistent with the flaw, while public evidence does not establish code execution.
