Description

StoredXSS-LibreNMS-Display Name 2

Description:

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

of Librenms versions 24.11.0 (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: "><img src onerror="alert(document.cookie)">. image
  4. Save the changes.
  5. The XSS payload is triggered when navigating to the path /device/$DEVICE_ID/logs and hovering over a type containing a tag (such as Core 1 in the image). image

Execution of Malicious Code
