CVE-2025-65804Public exploit

Code execution via iptvType stack overflow

Published Dec 8, 2025 · Updated Dec 8, 2025

Stack overflow in formSetIptv on Tenda AX3 16.03.12.11 allows attackers to execute code through a crafted iptvType parameter. The published proof of concept identifies iptvType as the input that overruns stack storage in formSetIptv; no lower-level copy operation is disclosed. Unauthenticated access from an adjacent network is sufficient; successful exploitation can crash the router or redirect control flow.
