Cacti is an open source performance and fault management framework. From version 1.2.27 to before version 1.2.31, Cacti contains an authenticated stored second-order SQL injection in the automation tree rule item handler. A user holding the Automation realm (default General Administration role) can persist an arbitrary SQL fragment in the automation_tree_rule_items.field column. The fragment is later concatenated directly into a SELECT ... AS source FROM ... clause in lib/api_automation.php :: create_all_header_nodes() and executed when an administrator triggers automation via the standard graphs.php?action=actions&drp_action=8 ("Apply Automation Rules") bulk action. The result of the injected SELECT is written into graph_tree_items.title and rendered in the Cacti tree UI, providing a direct exfiltration channe. This issue has been patched in version 1.2.31.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

Note that Nessus relies on the presence of the package as reported by the vendor.

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the 9647af6d-7a05-11f1-99fc-40b034429ecf advisory.

    Cacti project reports:
    This release includes fixes for a number of vulnerabilities that were responsibly disclosed by external     researchers

Tenable has extracted the preceding description block directly from the FreeBSD security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
