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.
