When the REST interface is enabled by the user, and an attacker gains access to the control network, and user/password broker authentication is enabled, and CVE-2025-6074 is exploited, the attacker can overflow the buffer for username or password.
CWE-121 - Stack-based Buffer OverflowWhen the REST interface is enabled by the user, and an attacker gains access to the control network, and CVE-2025-6074 is exploited, the attacker can use the JSON configuration to overflow the date of expiration field.
CWE-121 - Stack-based Buffer OverflowAttacker can gain access to salted information to decrypt MQTT information.

Recognize that VPNs may have vulnerabilities and should be updated to the most current version available. Also, understand that VPNs are only as secure as the connected devices.\n",
