CVE-2025-30406: Gladinet CentreStack and Triofox Use of Hard-coded Cryptographic Key Vulnerability

Critical severity, CVSS 9.8. Actively exploited: in CISA KEV since 2025-04-08. EPSS: 94.3% chance of exploitation in the next 30 days.

Gladinet CentreStack through 16.1.10296.56315 (fixed in 16.4.10315.56368) has a deserialization vulnerability due to the CentreStack portal's hardcoded machineKey use, as exploited in the wild in March 2025. This enables threat actors (who know the machineKey) to serialize a payload for server-side deserialization to achieve remote code execution. NOTE: a CentreStack admin can manually delete the machineKey defined in portal\web.config.
