Technical description

In Anjvision YSSD-RTMP-H5 firmware version 3.3.2.4, an empty-body POST to /setUserConfig, dispatched through the web server's SOAP-RPC handler, silently downgrades the administrator password to the default value and corrupts the in-memory authentication state until the device reloads. The handler does not verify the session's privilege level, so any authenticated user can trigger it.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
