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.
Public exploits
Exploit or proof-of-concept code for this vulnerability is publicly available, which lowers the bar for attackers. Treat it as a reason to patch sooner.
Third-party code, not reviewed by us. Public PoCs are sometimes fake or contain malware. Read the code first and run it only in an isolated lab, against systems you are authorised to test.
