CVE-2020-24217
Attackers can send an unauthenticated HTTP request to upload a custom firmware component, possibly in conjunction with command injection, to achieve arbitrary code execution.
Does this matter?
EPSS puts the probability of exploitation in the next 30 days at 40.3%, higher than 99% of all known CVEs. Patch or mitigate before the next change window.
Description
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.
