Zabbix 6.x < 6.0.37rc1 / 6.4.x < 6.4.21rc1 / 7.0.x < 7.0.7rc1 XSS (ZBX-26254)

high Nessus Plugin ID 233862

Synopsis

A web application running on the remote host is affected by a reflected cross-site scripting vulnerability.

Description

The version of Zabbix installed on the remote host affected by a reflected cross-site scripting (XSS) vulnerability. The endpoint /zabbix.php?action=export.valuemaps suffers from a Cross-Site Scripting vulnerability via the backurl parameter. This is caused by the reflection of user-supplied data without appropriate HTML escaping or output encoding. As a result, a JavaScript payload may be injected into the above endpoint causing it to be executed within the context of the victim's browser.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Zabbix version 6.0.37rc1, 6.4.21rc1, 7.0.7rc1 or later
