{"id":"CVE-2019-10665","aliases":["GHSA-q5rg-wg7h-73m5"],"url":"https://o3.security/vulnerability/CVE-2019-10665","summary":"LibreNMS Information Disclosure","details":"An issue was discovered in LibreNMS through 1.47. The scripts that handle the graphing options (html/includes/graphs/common.inc.php and html/includes/graphs/graphs.inc.php) do not sufficiently validate or encode several fields of user supplied input. Some parameters are filtered with mysqli_real_escape_string, which is only useful for preventing SQL injection attacks; other parameters are unfiltered. This allows an attacker to inject RRDtool syntax with newline characters via the html/graph.php script. RRDtool syntax is quite versatile and an attacker could leverage this to perform a number of attacks, including disclosing directory structure and filenames, file content, denial of service, or writing arbitrary files.","published":"2019-09-09T13:15:11.277Z","modified":"2026-07-08T15:54:12.672438Z","cvss":{"score":9.8,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":1,"affectedPackages":[{"ecosystem":"Packagist","name":"librenms/librenms","fixedVersion":null}],"fix":null,"references":[{"type":"EVIDENCE","url":"https://www.darkmatter.ae/xen1thlabs/librenms-rrdtool-injection-vulnerability-xl-19-023/"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-08T15:54:12.672438Z"}}
