Description

The vulnerability allows a remote user to execute arbitrary JavaScript in other users' sessions.

The vulnerability exists due to cross-site scripting in librenms/includes/html/pages/device/services.inc.php when handling the "descr" parameter in the device services editing workflow. A remote privileged user can submit a specially crafted service description to execute arbitrary JavaScript in other users' sessions.

User interaction is required when another user visits the device's "Services" tab, and the issue does not occur through the normal "Add Service" interface created through the ajax_form.php request with "type=create-service".


Remediation

Install security update from vendor's website.
