Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'), where the product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. In Librenms/librenms, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Summary The application fail to sanitising inputs properly and rendering the code from user input to browser which allow an attacker to execute malicious javascript code. ### Details User with Admin role can create a Device Groups, the application did not properly sanitize the user input in the Device Groups name, when user see the detail of the Device Group, if java script code is inside the name of the Device Groups, its will be trigger. ### PoC 1. Login as an Admin role user. Then go over to "$URL/device-groups" 2. Create a new Device Group with this payload in their name ```js <img src="x" onerror="alert(document.cookie)"> ``` ![image](https://github.com/user-attachments/assets/2764b313-ee65-47e9-ab57-559d75f4575c) 3. Go over to the detail page of that Device Groups, in this case "$URL/devices/group=2". Will see a pop-up. ![image](https://github.com/user-attachments/assets/f743ca74-5dcb-4e72-ac56-dda2b42e2986) ### Impact Attacker can use this to perform malicious java script code for malicious intent. This would impact all users as anyone can have access to the detail page of the device group.
