What is CVE-2026-100293?

The Anjvision YSSD-RTMP-H5 firmware version 3.3.2.4 exhibits a significant security flaw in its update mechanisms, both local and cloud-based. The system applies new firmware without adequate cryptographic verification, relying merely on basic hashing methods. This makes the update process susceptible to manipulation, allowing an attacker with access to the update routine to introduce malicious firmware images that the device will mistakenly accept as legitimate. This poses a serious risk, enabling potential exploitation and unauthorized control over the affected devices.

Affected Version(s)

YSSD-RTMP-H5 Version 3.3.2.4 build 2024-12-26
