CVE-2025-30406 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. 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. CISA has confirmed active exploitation in the wild. EPSS estimates a 92.73% chance of exploitation in the next 30 days.

Description
