Technical details
This is a cross-site request forgery (CSRF) vulnerability in WatchGuard Dimension's Web UI that affects the administrator passphrase change endpoint (CWE-352). The vulnerability arises from insufficient CSRF token validation on the passphrase change action. An attacker can craft a malicious link or webpage that, when visited by an authenticated global administrator, issues a request to change the administrator's passphrase without the administrator's knowledge or consent. The attack requires that the target administrator be actively authenticated to the Dimension Web UI. Successful exploitation grants the attacker full administrative access to the Dimension platform. The vulnerability is fixed in Dimension version 2.3.1 and later.
