CVE-2025-1814Network attack vector

Memory corruption via oversized wpapsk_crypto input

Published Mar 2, 2025 · Updated Mar 3, 2025

Stack-based buffer overflow in Tenda AC6 15.03.05.16 allows remote authenticated users to corrupt memory through WifiExtraSet. The /goform/WifiExtraSet handler accepts an oversized wpapsk_crypto request value, but the public record does not identify the unsafe copy operation or destination buffer. Low-privileged access to the web endpoint is required under the CNA assessment, and the record does not establish whether corruption causes a crash or code execution.
