## Key facts

- **Exploitation phase:** Limited Exploitation. The vulnerability is known but shows very limited attacker interest or exploitation activity.
- **CVSS score:** 9.0
- **Public exploit available:** Yes
- **Affected products:** Gladinet CentreStack

## 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.
