CVE-2022-25433Network attack vector

Unauthenticated stack corruption via crafted urls parameter

Published Mar 18, 2022 · Updated Aug 3, 2024

Stack overflow in Tenda AC9 15.03.2.21 allows remote attackers to cause unspecified impact via a crafted urls parameter. Public records identify the saveparentcontrolinfo handler and its urls input but do not disclose the unsafe operation or buffer-handling path. Network access without authentication is sufficient; the established consequence is stack memory corruption, while code execution has not been demonstrated.
