KEVCRITICAL 9.8EPSS 94.3%

Does this matter?

Known to be exploited in the wild (CISA KEV, CISA remediation deadline 29 April 2025). Treat as an emergency change: patch or isolate now, then hunt for prior compromise.

Description

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.
