CVE-2025-23201
Librenms has a reflected XSS on error alert
Impact
XSS on the parameters:`/addhost` -> param: community of Librenms versions 24.10.1 ([https://github.com/librenms/librenms](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. Navigate to the /addhost path. 2. Fill in all required fields. 3. In the Community field, enter the following payload: `"><img src=a onerror="alert(1)">`.  4. Submit the form to save changes. 5 The script will execute when the error alert "No reply with community + payload" appears.  **Impact:** Execution of Malicious Code
