Jabber Studio jabberd SASL Negotiation Remote DoS

medium Nessus Plugin ID 21120
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


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


The remote host is running jabberd, an open source messaging system based on the Jabber protocol.

The version of jabberd installed on the remote host suffers a segfault 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.


Upgrade to jabberd 2s11 or later.
