Router crash via oversized IPTV VLAN value
Published Aug 26, 2024 · Updated Mar 18, 2025
Stack-based buffer overflow in formGetIptv in Tenda AX1806 1.0.0.1 allows attackers to crash the router via a crafted IPTV value. The handler processes the adv.iptv.stballvlans parameter into a stack buffer without enforcing the buffer's capacity. Public assessments disagree on reachability: NVD rates the path unauthenticated over a network, while CISA rates it local with low privileges; the published record does not establish code execution beyond the documented overflow.
