The Jabberd, before 2.6.1 allows anyone to authenticate SASL ANONYMOUS, even when sasl.anonymous c2s.xml option is not enabled. Please, update port to 2.6.1.
Assuming this is for net-im/jabberd (currently 2.5.0), assign to maintainer (mm) accordingly. Is net-im/jabber port (no maintainer) also vulnerable?
Probably not, it doesn't have SASL at all.
