CVE-2020-24217: Szuray iptv\/h.264 video encoder firmware missing authentication for critical function vulnerability

Szuray · Iptv\/H.264 Video Encoder Firmware

An issue was discovered in the box application on HiSilicon based IPTV/H.264/H.265 video encoders. The file-upload endpoint does not enforce authentication. Attackers can send an unauthenticated HTTP request to upload a custom firmware component, possibly in conjunction with command injection, to achieve arbitrary code execution.
