Remote compromise via unchecked time parameter
Published Dec 20, 2023 · Updated Jul 9, 2026
Out-of-bounds write in sysTimeInfoSet in Tenda i29 firmware 1.0.0.5 allows remote attackers to compromise the device via network requests. The function processes an attacker-controlled time parameter without sufficient bounds validation, causing a buffer overflow. Unauthenticated network access is sufficient; memory corruption can interrupt or compromise the service, but the exact exploit outcome is not publicly detailed.
