Summary
LibreNMS Display Name Stored Cross-site Scripting vulnerability
Details

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>. Screenshot from 2024-11-06 09-41-37

  1. Save the changes.
  2. The XSS payload triggers when accessing the "/apps" path (if an application was previously added). Screenshot from 2024-11-06 09-42-05

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

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

  2. on /device/$DEVICE_ID/ports/arp path: image

  3. on /device/$DEVICE_ID/logs path: image

  4. on /search/search=arp/ path: image

Impact:
