CVE-2024-35344Public exploitNetwork attack vector

Credential disclosure via shared firmware encryption key

Published May 28, 2024 · Updated Feb 13, 2025

Hard-coded key use in ANPVIZ YMF50B firmware 3.2.2.2 and earlier allows remote authenticated users to decrypt stored passwords. The StringEncrypt routine in libtools.so encrypts configuration passwords with one embedded 256-bit AES key shared across devices. Attackers must obtain the library and encrypted configuration; companion unauthenticated file-download flaws expose both remotely, enabling administrator credential recovery.
