GHSA-2f4w-6mc7-4w78 LibreNMS Display Name 2 Stored Cross-site Scripting vulnerability

• Packagist librenms/librenms: >= 24.11.10, < 24.12.0 → fixed in 24.12.0

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: `">`. 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). Impact: Execution of Malicious Code
