{"id":"CVE-2023-48294","aliases":["GHSA-fpq5-4vwm-78x4"],"url":"https://o3.security/vulnerability/CVE-2023-48294","summary":"Broken Access control on Graphs Feature in LibreNMS","details":"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.","published":"2023-11-17T21:12:59.642Z","modified":"2026-08-12T03:51:45.944248511Z","cvss":{"score":4.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":1,"affectedPackages":[{"ecosystem":"Packagist","name":"librenms/librenms","fixedVersion":"23.11.0"}],"fix":{"url":"https://github.com/librenms/librenms/commit/489978a923ed52aa243d3419889ca298a8a6a7cf","label":"librenms/librenms@489978a"},"references":[{"type":"WEB","url":"https://github.com/librenms/librenms/blob/fa93034edd40c130c2ff00667ca2498d84be6e69/html/graph.php#L19C1-L25C2"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/48xxx/CVE-2023-48294.json"},{"type":"ADVISORY","url":"https://github.com/librenms/librenms/security/advisories/GHSA-fpq5-4vwm-78x4"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-48294"},{"type":"FIX","url":"https://github.com/librenms/librenms/commit/489978a923ed52aa243d3419889ca298a8a6a7cf"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:45.944248511Z"}}
