Unauthenticated code execution via time parameter overflow
Published Mar 28, 2022 · Updated Aug 3, 2024
Stack overflow in Tenda AC9 15.03.2.21_cn allows remote attackers to execute code or crash the router via a crafted time parameter. The PowerSaveSet function processes the attacker-controlled time value into a stack buffer, but public material does not identify the exact unsafe copy or parsing operation. No authentication or user interaction is required; an oversized request can corrupt control data and compromise or interrupt the router.
