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

**Signal:** Exploited: patch now if you run it. CISA has confirmed exploitation in the wild. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- Yes, if you run Gladinet CentreStack. CISA added this CVE to its Known Exploited Vulnerabilities catalog on 2025-04-08, which means there is reliable evidence of exploitation in the wild. US federal agencies must remediate by 2025-04-29 ; treat that as the outer limit, not the target.
- EPSS 94.3% , percentile 99.9: FIRST’s model estimates a 94.3% chance of exploitation activity in the next 30 days, higher than 99.9% of all scored CVEs (very high). EPSS is a probability, not a verdict.
- Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.

## What it is

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.

## Affected products (CVE record)
