CVE-2020-24214: An issue was discovered in the box application on HiSilicon based IPTV/H.264/H.265 video encoders
CVE-2020-24214 is a critical-severity flaw (CVSS 9.8) affecting iptv\/h.264 video encoder firmware, iptv\/h.265 video encoder firmware, h.264 iptv encoder 1080p\@60hz firmware. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
An issue was discovered in the box application on HiSilicon based IPTV/H.264/H.265 video encoders. Attackers can send a crafted unauthenticated RTSP request to cause a buffer overflow and application crash. The device will not be able to perform its main purpose of video encoding and streaming for up to a minute, until it automatically reboots. Attackers can send malicious requests once a minute, effectively disabling the device.
