CVE-2024-56144

CVE-2024-56144: LibreNMS Display Name 2 Stored Cross-site Scripting vulnerability

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:

Add a new device through the LibreNMS interface.
Edit the newly created device by going to the "Device Settings" section.
In the "Display Name" field, enter the following payload: "><img src onerror="alert(document.cookie)">.
Save the changes.
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

Root Cause Analysis

The vulnerability stems from improper output escaping in link generation functions. The provided commit diff shows systematic replacement of Url::deviceLink and Url::portLink with Blade components (which auto-escape by default) across multiple controllers. The advisory explicitly states these functions' overlib HTML generation caused escaping difficulties. The XSS occurs when unsanitized user input from the 'display' parameter is rendered in pages like /device/$DEVICE_ID/logs, which would have been processed by these vulnerable functions prior to the patch.
