How to fix?

Upgrade librenms/librenms to version 1.50.1 or higher.

Overview

librenms/librenms is a fully featured network monitoring system that provides a wealth of features and device support.

Affected versions of this package are vulnerable to Command Injection. It is possible to inject arbitrary commands in html/includes/graphs/device/collectd.inc.php where user supplied parameters are filtered with the mysqli_escape_real_string function. This function is not the appropriate function to sanitize command arguments as it does not escape a number of command line syntax characters such as backticks, allowing an attacker to inject commands into the variable $rrd_cmd, which gets executed via passthru().
