Summary
Gladinet CentreStack, a file-sharing and remote-access server product, is affected because its portal uses a hardcoded machine key. An attacker who knows that key can craft malicious serialized data that the server processes, allowing them to run arbitrary code on the server.

Read the original 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.
