Published: 5/24/2022Modified: 4/24/2024
Description
LibreNMS 1.46 allows remote attackers to execute arbitrary OS commands by using the `$_POST['community']` parameter to `html/pages/addhost.inc.php` during creation of a new device, and then making a `/ajax_output.php?id=capture&format=text&type=snmpwalk&hostname=localhost request that triggers html/includes/output/capture.inc.php` command mishandling.
