Authenticated device compromise via Time parameter overflow
Published May 31, 2026 · Updated May 31, 2026
Stack-based buffer overflow in Tenda W12 3.0.0.7(4763) allows remote authenticated users to compromise the device via the Time parameter. The set_local_time_0 function in /bin/httpd processes attacker-controlled Time data without enforcing the destination stack buffer's bounds. Access to the HTTP management service and low privileges are required; exploitation corrupts process memory and can affect device confidentiality, integrity, and availability.
