Description
GeoNetwork core-geonetwork versions from 3.0.0 up to 4.2.15 and 4.4.10 are vulnerable to a cross-site scripting (XSS) flaw. This occurs when a nonexistent or unauthorized service URL causes an error page to reflect attacker-controlled input inside an AngularJS application without proper sanitization. An attacker can craft a link that, when opened by a victim, including administrators, executes arbitrary JavaScript in the victim's authenticated browser session. This vulnerability is fixed in versions 4.2.15 and 4.4.10.
