In phpsysinfo, the XML.php file has a JSONP hijacking vulnerability. When a user visits a page carefully crafted by the attacker, the JSON data is obtained and sent to the attacker, such as IP addresses, server names, network topologies, and other data that could be used to map out the internal network structure. This information could then be used to identify additional targets within the network and launch more targeted attacks. The issue is patched in version 3.4.3.
