CVE-2025-29032Public exploitNetwork attack vector

Service crash via unchecked WPS index copy

Published Mar 14, 2025 · Updated Mar 19, 2025

Buffer overflow in Tenda AC9 firmware 15.03.05.19(6318) allows remote authenticated users to crash the service via a crafted WPS request. In formWifiWpsOOB, sprintf copies the attacker-controlled index value and a delimiter into the four-byte s buffer without checking its length. CISA's assessment requires low privileges and user interaction; the demonstrated consequence is a process crash.
