Actively exploited (CISA KEV)

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.

Added to KEV: 8 Apr 2025Federal remediation due: 29 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.

How Secuno handles this

Secuno correlates vulnerabilities like CVE-2025-30406 against the real software inventory on every managed device, as each hourly inventory arrives. Rather than a static severity, each match is scored in context: exploit availability, EPSS, the asset's exposure, and business criticality decide where it lands in the queue. Because it is on the CISA KEV list, a risk for it never ranks below high, and the update that fixes it moves to the Emergency patch lane. If an affected version is present anywhere across your portfolio, it surfaces automatically with a prioritised remediation path.
