Vulnerability from github
StoredXSS-LibreNMS-Ports
Description:
Stored XSS on the parameter:
/ajax_form.php -> param: descr
Request: ```http POST /ajax_form.php HTTP/1.1 Host: X-Requested-With: XMLHttpRequest X-CSRF-TOKEN: Content-Type: application/x-www-form-urlencoded; charset=UTF-8 Cookie:
type=update-ifalias&descr=%22%3E%3Cimg+src+onerror%3D%22alert(1)%22%3E&ifName=lo&port_id=1&device_id=1 ```
of Librenms version 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 and select the "ports" section.
3. In the "Description" field, enter the following payload: "><img src onerror="alert(1)">.
4. Save the changes.
5. The XSS vulnerability is triggered when accessing the "ports" tab, and the payload is executed again when hovering over the modified value in the "Port" field.
Payload:
Executes:
The script execution vulnerability in the description field, as shown in the image, occurs at Line 63 of functions.inc.php
php
$overlib_content = '<div class=overlib><span class=overlib-text>' . $text . '</span><br />';
Impact:
Execution of Malicious Code
