The vulnerability allows a remote attacker to disclose sensitive information and perform server-side request forgery.
The vulnerability exists due to improper restriction of xml external entity reference in the WFS service XSD schema handling when parsing XML requests. A remote attacker can send a specially crafted XML request to disclose sensitive information and perform server-side request forgery.
