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

CVE-2025-30406 is rated critical with a CVSS v3.1 base score of 9.8 and affects Gladinet CentreStack. Per its scoring, it can be exploited over the network, without authentication, without any user interaction. The scored impact on confidentiality, integrity and availability is the highest available. CISA added it to its Known Exploited Vulnerabilities catalog on 2025-04-08, which means exploitation in the wild has been observed.

Vulnerability 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.
