CVE-2025-23198

librenms is a community-based GPL-licensed network monitoring system. Affected versions are subject to a stored XSS on the parameters (Replace $DEVICE_ID with your specific $DEVICE_ID value):/device/$DEVICE_ID/edit -> param: display. Librenms versions up to 24.10.1 allow remote attackers to inject malicious scripts. When a user views or interacts with the page displaying the data, the malicious script executes immediately, leading to potential unauthorized actions or data exposure. This issue has been addressed in release version 24.11.0. Users are advised to upgrade. There are no known workarounds for this vulnerability.

Description:

XSS on the parameters (Replace $DEVICE_ID with your specific $DEVICE_ID value):/device/$DEVICE_ID/edit -> param: display

of Librenms versions 24.9.0, 24.10.0, and 24.10.1 (https://github.com/librenms/librenms) allows remote attackers to inject malicious scripts. When a user views or interacts with the page displaying the data, the malicious script executes immediately, leading to potential unauthorized actions or data exposure.

Proof of Concept:

1. Add a new device through the LibreNMS interface.

2. Edit the newly created device by going to the "Device Settings" section.

3. In the "Display Name" field, enter the following payload: "><script>alert(1)</script>.

4. Save the changes.

5. The XSS payload triggers when accessing the "/apps" path (if an application was previously added).

Additional PoC:

1. In the "Display Name" field, enter the following payload: "><img src onerror="alert(1)">.

2. The XSS vulnerability is triggered when accessing the "/ports" path, and the payload executes when hovering over the modified value in the "Port" field.

• on /device/$DEVICE_ID/logs path:

• on /search/search=arp/ path:

Impact:

Execution of Malicious Code
