CVE-2025-30406 (GCVE-0-2025-30406)
Vulnerability from cvelistv5 – Published: 2025-04-03 00:00 – Updated: 2025-10-21 22:55Summary
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.
