September 18, 2025 CISA ICS Advisory

Summary

Successful exploitation of these vulnerabilities could result in a remote attacker causing a denial-of-service condition or gaining administrative access to the device. CVE-2025-55068: Affected devices fail to handle Unix time values beyond a certain point. An attacker can manually change the system time to exploit this limitation, potentially causing errors in authentication and leading to a denial of service condition. CVE-2025-54807: The secret used for validating authentication tokens is hardcoded in device firmware for affected versions. An attacker who obtains the signing key can bypass authentication, gaining complete access to the system. CVE-2025-30519: Affected versions of the device have default root credentials that cannot be changed through standard administrative means. An attacker with network access to the device can gain administrative access to the system.
