The Ignite Realtime Smack XMPP API 4.x before 4.0.2, and 3.x and 2.x when a custom SSLContext is used, does not verify that the server hostname matches a domain name in the subject's Common Name (CN) or subjectAltName field of the X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via an arbitrary valid certificate.

The ServerTrustManager component in the Ignite Realtime Smack XMPP API before 4.0.0-rc1 does not verify basicConstraints and nameConstraints in X.509 certificate chains from SSL servers, which allows man-in-the-middle attackers to spoof servers and obtain sensitive information via a crafted certificate chain.

The ParseRoster component in the Ignite Realtime Smack XMPP API before 4.0.0-rc1 does not verify the from attribute of a roster-query IQ stanza, which allows remote attackers to spoof IQ responses via a crafted attribute.

nio/XMLLightweightParser.java in Ignite Realtime Openfire before 3.9.2 does not properly restrict the processing of compressed XML elements, which allows remote attackers to cause a denial of service (resource consumption) via a crafted XMPP stream, aka an "xmppbomb" attack.

Ignite Realtime Openfire before 3.6.5 does not properly implement the register.password (aka canChangePassword) console configuration setting, which allows remote authenticated users to bypass intended policy and change their own passwords via a passwd_change IQ packet.

The jabber:iq:auth implementation in IQAuthHandler.java in Ignite Realtime Openfire before 3.6.4 allows remote authenticated users to change the passwords of arbitrary accounts via a modified username element in a passwd_change action.

Cross-site scripting (XSS) vulnerability in login.jsp in the Admin Console in Openfire 3.6.0a and earlier allows remote attackers to inject arbitrary web script or HTML via the url parameter.

Open redirect vulnerability in login.jsp in Openfire 3.6.0a and earlier allows remote attackers to redirect users to arbitrary web sites and conduct phishing attacks via the url parameter.

SQL injection vulnerability in CallLogDAO in SIP Plugin in Openfire 3.6.0a and earlier allows remote attackers to execute arbitrary SQL commands via the type parameter to sipark-log-summary.jsp.

Directory traversal vulnerability in the AuthCheck filter in the Admin Console in Openfire 3.6.0a and earlier allows remote attackers to bypass authentication and access the admin interface via a .. (dot dot) in a URI that matches the Exclude-Strings list, as demonstrated by a /setup/setup-/.. sequence in a URI.
