CVE-2025-27594
Unencrypted transmission of password hash
The device uses an unencrypted, proprietary protocol for communication. Through this protocol, configuration data is transmitted and device authentication is performed. An attacker can thereby intercept the authentication hash and use it to log into the device using a pass-the-hash attack.
