CVSS 3.1
9.8 criticalCVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:HCVE-2020-24214
Critical (9.8). EPSS 35% chance of exploitation in the next 30 days.
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.
