9.8 criticalCVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:HCVE-2020-24217
Critical (9.8). EPSS 40% 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. 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.
