Description
Zabbix frontend supported an XML data import feature, where on the server it used DOMDocument to parse the XML. By default, DOMDocument also parses the external DTD, which could allow a remote attacker to use a crafted XML file causing Zabbix to read an arbitrary local file, and send the contents of the specified file to a remote server.
Affected versions: 1.8.19, 1.8.20, 2.0.9, 2.0.10, 2.0.11rc2, 2.0.11, 2.2.2, 2.2.3rc1, 2.2.3rc2, 2.2.3
