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

Published Apr 3, 2025 · corrected/updated Jun 17, 2026 · Gladinet CentreStack · evidence confidence very high

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.

Grounded briefings

Catalog interpretations for three audiences. Each brief cites ingested metadata and the original advisories below. They are not independent research and they do not invent exploit steps.

Executive

CVE-2025-30406 is a critical public vulnerability record for Gladinet CentreStack. CISA lists it as known exploited. Published remediation guidance: Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable. This summary is a catalog interpretation of the ingested metadata and cites the original advisories below.

System administrator

Identify whether Gladinet CentreStack is in your estate, then compare installed versions with the affected ranges. Affected packages or ranges on record: gladinet/centrestack; Gladinet CentreStack. Published remediation guidance: Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable. Prefer the vendor or distribution advisory linked in Sources before changing production systems. This is a catalog interpretation, not a runbook.

Security analyst

Signals on file: CVSS 9.8, EPSS 94.3%. CISA lists it as known exploited. Weakness classes: CWE-321, CWE-798. Sources contributing to this record: attackerkb, cisa_kev, cve_org, epss. Public exploit references, when present, are outbound links only and are not proof of active exploitation. This is a catalog interpretation of stored metadata.
