2. Avaya System Products using a Sun Microsystems Operating System with Kerberos installed:

Some Avaya system products are delivered with an Operating System from Sun Microsystems. Actions to be taken on these products are described below.

Product: Affected Version(s): Risk Level: Actions:
Avaya CMS R13/R13.1, R14/R14.1, R15 Low Kerberos is installed but not configured or used by default on CMS systems.
For CMS R13/R14 upgrade to R13.1/R14.1 and install patch 119208-24.
For CMS R13.1/R14.1 install patch 119208-24.
For CMS R15 install patch 138371-06.

Recommended Actions:
Avaya strongly recommends that customers follow networking and security best practices by implementing firewalls, ACLs, physical security or other appropriate access restrictions. Though Avaya believes such restrictions should always be in place; risk to Avaya's product and the surrounding network from this potential vulnerability may be mitigated by ensuring these practices are implemented until such time as a product update can be installed. Further restrictions as deemed necessary based on the customer's security policies may be required during this interim period.
