CVE-2022-37813Public exploitNetwork attack vector

Memory corruption via fromSetSysTime stack overflow

Published Aug 25, 2022 · Updated Aug 3, 2024

Stack-based buffer overflow in Tenda AC1206 firmware 15.03.06.23 allows remote attackers to corrupt memory via crafted network requests. The public record identifies fromSetSysTime as the vulnerable function but does not disclose the triggering parameter or the operation that overruns its stack buffer. Network access without authentication or user interaction reaches the flaw; public materials do not establish whether exploitation stops at a crash or permits code execution.
