CVE-2020-15875
An issue was discovered in LibreNMS 1.65. A remote authenticated attacker with normal privileges can extract all the information from the LibreNMS database via a SQL injection in the searchPhrase parameter in the /ajax_table.php API endpoint. This affects as-selection.inc.php, edit-ports.inc.php, alertlog-stats.inc.php, alerts.inc.php, eventlog.inc.php, inventory.inc.php, ix-list.inc.php, ix-peers.inc.php, mempool-edit.inc.php, mempool.inc.php, poll-log.inc.php, processor-edit.inc.php, processor.inc.php, routing-edit.inc.php, sensors-common.inc.php, storage-edit.inc.php, storage.inc.php, and toner.inc.php (in includes/html/table). NOTE: some sources refer to this as CVE-2020-15876, but CVE-2020-15875 is the only correct CVE ID.
