CVE ID CVSS Score Severity Description
CVE-2026-55985 4.3 medium
The device's web management interface stores and displays system credentials in cleartext on a certain configuration page accessible to authenticated users. Any party with access to the administrative dashboard can immediately read these credentials, which may be used to compromise other systems on the local network.
CVE-2026-61884 9.8 critical
The device ships without HTTP credentials configured, intended for an installer to set them on first use. On firmware 2.4.4 and earlier, a unit left in this unconfigured state serves the web management interface without requiring any login. An attacker with network access to such a unit can reach full device controls, including power relay management, device reboot, remote access service configuration, and network settings, which could allow disruption of connected infrastructure or physical damage to equipment.

Mitigation: Tycon Systems recommends changing any factory-default SNMP community strings and the Telnet password
Tycon Systems recommends changing any factory-default SNMP community strings and the Telnet password if they were left at shipped values. Leave Telnet disabled unless required.
