openfire -- multiple vulnerabilities

Andreas Kurtz reports:

The jabber server Openfire (<= version 3.6.0a) contains several
serious vulnerabilities. Depending on the particular runtime
environment these issues can potentially even be used by an
attacker to execute code on operating system level.

Authentication bypass - This vulnerability provides an attacker
full access to all functions in the admin webinterface without
providing any user credentials. The Tomcat filter which is
responsible for authentication could be completely
circumvented.
SQL injection - It is possible to pass SQL statements to the
backend database through a SQL injection vulnerability. Depending
on the particular runtime environment and database permissions it
is even possible to write files to disk and execute code on
operating system level.
Multiple Cross-Site Scripting - Permits arbitrary insertion
of HTML- and JavaScript code in login.jsp. An attacker could
also manipulate a parameter to specify a destination to which a
user will be forwarded to after successful authentication.
