CVE-2025-30406

Gladinet CentreStack and Triofox Use of Hard-coded Cryptographic Key Vulnerability

Critical 9.0
Exploited: added to CISA KEV 8 Apr 2025

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.
