Detailed Explanation for this Vulnerability Test

Synopsis :

The remote instant messaging server is affected by a denial of service

Description :

when a client sends a SASL 'response' stanza before a SASL 'auth'
stanza. An unauthenticated remote attacker can leverage this flaw to
crash the application's c2s component, thereby denying service to
legitimate users.
