An authentication bypass vulnerability in the Password Reset component of Gladinet CentreStack before 13.5.9808 allows remote attackers to set a new password for any valid user account, without needing the previous known password, resulting in a full authentication bypass.

An unrestricted file upload vulnerability in the administrative portal branding component of Gladinet CentreStack before 13.5.9808 allows authenticated attackers to execute arbitrary code by uploading malicious files to the server.

In the default installation and configuration of Gladinet CentreStack and TrioFox, there is an unauthenticated Local File Inclusion Flaw that allows unintended disclosure of system files. Exploitation of this vulnerability has been observed in the wild.  This issue impacts Gladinet CentreStack and Triofox: All versions prior to and including 16.7.10368.56560

Triofox versions prior to 16.7.10368.56560, are vulnerable to an Improper Access Control flaw that allows access to initial setup pages even after setup is complete.

Gladinet CentreStack and Triofox prior to version 16.12.10420.56791 used hardcoded values for their implementation of the AES cryptoscheme. This degrades security for public exposed endpoints that may make use of it and may offer arbitrary local file inclusion when provided a specially crafted request without authentication. This opens the door for future exploitation and can be leveraged with previous vulnerabilities to gain a full system compromise.

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.
