Overview

AI description

Automated description summarized from trusted sources.

CVE-2025-30406 is a vulnerability affecting Gladinet CentreStack, a cloud-based enterprise file-sharing platform. It stems from the use of a hard-coded cryptographic key within the application's web configuration files (web.config). This key is used for ViewState integrity verification. Successful exploitation of this flaw allows an attacker to forge ViewState payloads. This enables server-side deserialization, ultimately leading to remote code execution. The vulnerability is classified as CWE-321, which highlights the risks associated with using hard-coded cryptographic keys.

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.

Insights

Analysis from the Intruder Security Team

Published Apr 14, 2025 Updated Apr 14, 2025

This vulnerability is caused by the installer for the application using a hardcoded value for the validation and decryption key (sometimes known as the machine keys). These values are the same for all instances created by the vulnerable installer, and so an attacker can find these keys for your instance very easily.

If an attacker possesses these keys, they can execute code of their choice on the server remotely using well-known methods.

Updating to the latest version will cause the keys to be regenerated to secret values.
