XSS on the parameters:/addhost -> param: community
of Librenms versions 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:
-
Navigate to the /addhost path.
-
Fill in all required fields.
-
In the Community field, enter the following payload:
"><img src=a onerror="alert(1)">. -
Submit the form to save changes. 5 The script will execute when the error alert "No reply with community + payload" appears.
