CRITICAL 9.8

DescriptionNVD

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.

AnalysisAI

An issue was discovered in the box application on HiSilicon based IPTV/H.264/H.265 video encoders. Rated critical severity (CVSS 9.8), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available and no vendor patch available.

Technical ContextAI

This vulnerability is classified as Missing Authentication for Critical Function (CWE-306), which allows attackers to access critical functionality without authentication. 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. Affected products include: Szuray Iptv\/H.264 Video Encoder Firmware, Szuray Iptv\/H.265 Video Encoder Firmware, Jtechdigital H.264 Iptv Encoder 1080P\@60Hz Firmware, Provideoinstruments Vecaster-Hd-H264 Firmware, Provideoinstruments Vecaster-Hd-Hevc Firmware.

RemediationAI

No vendor patch is available at time of analysis. Monitor vendor advisories for updates. Require authentication for all sensitive operations, implement defense in depth.
