### Summary The json-web-token library is vulnerable to a JWT algorithm confusion attack. ### Details On line 86 of the 'index.js' file, the algorithm to use for verifying the signature of the JWT token is taken from the JWT token, which at that point is still unverified and thus shouldn't be trusted. To exploit this vulnerability, an attacker needs to craft a malicious JWT token containing the HS256 algorithm, signed with the public RSA key of the victim application. This attack will only work against this library is the RS256 algorithm is in use, however it is a best practice to use that algorithm. ### PoC Take a server running the following code: ```javascript const express = require('express'); const jwt = require('json-web-token'); const fs = require('fs'); const path = require('path'); const app = express(); const port = 3000; // Load the keys from the file const publicKeyPath = path.join(__dirname, 'public-key.pem'); const publicKey = fs.readFileSync(publicKeyPath, 'utf8'); ...

LibreNMS is an auto-discovering PHP/MySQL/SNMP based network monitoring which includes support for a wide range of network hardware and operating systems. In affected versions of LibreNMS when a user accesses their device dashboard, one request is sent to `graph.php` to access graphs generated on the particular Device. This request can be accessed by a low privilege user and they can enumerate devices on librenms with their id or hostname. Leveraging this vulnerability a low privilege user can see all devices registered by admin users. This vulnerability has been addressed in commit `489978a923` which has been included in release version 23.11.0. Users are advised to upgrade. There are no known workarounds for this vulnerability.

joaquimserafim/json-web-token is a javascript library use to interact with JSON Web Tokens (JWT) which are a compact URL-safe means of representing claims to be transferred between two parties. Affected versions of the json-web-token library are vulnerable to a JWT algorithm confusion attack. On line 86 of the 'index.js' file, the algorithm to use for verifying the signature of the JWT token is taken from the JWT token, which at that point is still unverified and thus shouldn't be trusted. To exploit this vulnerability, an attacker needs to craft a malicious JWT token containing the HS256 algorithm, signed with the public RSA key of the victim application. This attack will only work against this library is the RS256 algorithm is in use, however it is a best practice to use that algorithm.

### Summary This vulnerability occurs when application is not checking access of each type of users as per their role and it autorizing the users to access any feature. When user access his Device dashboard in librenms, one request is going to graph.php to access image of graphs generated on the particular Device. This request can be accessed by lower privileged users as well and they can enumerate devices on librenms with their id or hostname. ### Details _Give all details on the vulnerability. Pointing to the incriminated source code is very helpful for the maintainer._ ### PoC 1. Login with Lower privilege user 2. Go to /graph.php?width=150&height=45&device=1&type=device_ping_perf&from=1699022192&legend=no&bg=FFFFFF00&popup_title=ICMP+Response 3. If its showing image with "device*ping_perf" which confirms that there is device with id 1 4. Now you can change device parameter in above URL with hostname to check if that Hostname/IP exist or not like http://127.0.0.1:8000/graph.php?wi...
