How to detect it

Nuclei template (active check)

Geonetwork - Cross-Site Scripting
GeoNetwork versions 4.4.5 through 4.4.11 are vulnerable to reflected cross-site scripting (XSS) in the public unauthenticated catalog search functionality. The uiconfig query parameter of the catalog.search endpoint is reflected into a JavaScript context without sufficient sanitization, allowing arbitrary JavaScript execution in a victim’s browser.

Name and description quoted from the template, written by VEDAS.

The template sends 1 request (GET /srv/eng/catalog.search?uiconfig=%28alert%281%29%2C%7B%7D%29); it decides using word matchers. Severity in the template: high. Marked as not yet verified against a live vulnerable target.

Run it against a host you own or are authorised to test:
