Reflected XSS issues

Vulnerability

A Cross-site Scripting (XSS) vulnerability exists in the web GUI of Secomea GateManager. This flaw allows an attacker to inject arbitrary JavaScript code into the application. The issue affects all versions of Secomea GateManager prior to version 9.4 [1].

Exploitation

An attacker can exploit this vulnerability by crafting a malicious URL or input that, when processed by the vulnerable web GUI, executes arbitrary JavaScript in the context of the victim's browser. No special network position or authentication is required beyond the ability to deliver the payload to an authenticated user of the GateManager web interface.

Impact

Successful exploitation enables the attacker to execute arbitrary JavaScript code in the victim's browser session. This can lead to session hijacking, defacement, or theft of sensitive information displayed or managed through the GateManager web GUI. The attacker operates at the user's privilege level.

Mitigation

The vulnerability is fixed in Secomea GateManager version 9.4. Users should upgrade to this version or later. Secomea's cybersecurity advisory provides general information about their vulnerability handling process; no workaround is noted for versions prior to 9.4 [1].
