Product Description:
Openfire is a real time collaboration (RTC) server licensed under the
Open Source GPL. It uses the only widely adopted open protocol for
instant messaging, XMPP (also called Jabber). Openfire is incredibly
easy to setup and administer, but offers rock-solid security and
performance.

Vulnerability Details:
An attacker can execute functions as an authenticated user by tricking a
user into making requests to the Server. The attack works by including a
link or script in a page that accesses a site to which the user is known
(or is supposed) to have been authenticated. Successful exploitation of
these vulnerabilities could result in, but not limited to, compromise of
the application, theft of cookie-based authentication credentials,
arbitrary page redirection, disclosure or modification of sensitive data
and phishing attacks.

Since the vulnerabilities exist in the administrative module, a
successful attack could cause a complete compromise of the entire
application. An attacker can send a link with the exploit to an
administrator whose access could compromise the application.

Proof of Concept:
Create a html content (img, iframes etc.) with the following PoC URLs as
src and host for the authenticated victim.
http://localhost:9090/user-create.jsp?username=tester&name=Riyaz&email=w
alikarriyazad%40microland.com&password=test&passwordConfirm=test&isadmin
=on&create=Create+User
