CVE-2024-44557

Memory corruption via unbounded IPTV mode input

Published Aug 26, 2024 · Updated Aug 26, 2024

Stack overflow in Tenda AX1806 Firmware 1.0.0.1 allows attackers to corrupt memory through a crafted IPTV mode value. Public material identifies the iptv.stb.mode parameter and setIptvInfo function but does not disclose the exact copy operation or buffer size. Published assessments disagree on the gate: NVD rates unauthenticated network reachability, while CISA rates adjacent authenticated access; neither demonstrates code execution.
