CVE-2025-13399

A weakness in the web interface’s application layer encryption in VX800v v1.0 allows an adjacent attacker to brute force the weak AES key and decrypt intercepted traffic. Successful exploitation requires network proximity but no authentication, and may result in high impact to confidentiality, integrity, and availability of transmitted data.
