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

Gladinet CentreStack and Triofox contains a use of hard-coded cryptographic key vulnerability in the way that the application manages keys used for ViewState integrity verification. Successful exploitation allows an attacker to forge ViewState payloads for server-side deserialization, allowing for remote code execution.

What CISA says

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

Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.

NVD description · published 2025-04-03

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.

How to check if you are exposed to CVE-2025-30406

Find every Gladinet CentreStack system you or your clients run, including ones exposed to the internet. Those come first: CISA only lists flaws attackers are already using.
Compare each version with the fixed versions in the vendor advisory below. Where no fix exists yet, apply the vendor’s mitigation or take the system off the internet.
Run a credentialed vulnerability scan to catch the systems you missed, then check that the next scan no longer reports CVE-2025-30406.

US federal agencies had to fix this by 2025-04-29. Everyone else should treat that deadline as a guide: if it has passed, this is overdue.
