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.
