Ignite Realtime supports Openfire, a Jabber server. It’s a Java program that serves as a platform for medium-sized businesses to manage internal communications and make instant messaging more convenient. The FaviconServlet in earlier versions of the Openfire Admin Console is vulnerable to a full read SSRF vulnerability. Attackers can use this vulnerability to send arbitrary HTTP GET queries to the internal network and view the responses.
We suggest that you upgrade to the most recent version.
