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

Weaponization
Public repositories whose name or description references CVE-2025-30406, found via a live GitHub search at request time. These are community-sourced signals, not a verified working exploit - cross-check each one before relying on it, and treat higher star counts and recent activity as (weak) corroboration, not proof.
No public GitHub repositories referencing CVE-2025-30406 were found at last check. Absence here is not proof no exploit exists - see the references below for vendor advisories and write-ups.
