Remote stack overflow in saveparentcontrolinfo

Published Feb 22, 2022 · Updated Aug 3, 2024

Stack overflow in Tenda AC9 V15.03.2.21_cn allows remote attackers to corrupt memory via the saveparentcontrolinfo function. The public record identifies saveparentcontrolinfo as the vulnerable locus but does not disclose which parameter handling or copy operation overruns the stack. Unauthenticated network access is sufficient to reach the function; published material does not establish a reliable outcome beyond stack corruption or confirm code execution.
