2. Avaya System Products using a Sun Microsystems Operating System with NTP Service 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 R14/R14.1, R15, R16 Low The use of CMS as an NTP server is not supported and so a patch will not be tested, however, the workaround described in the Sun alert may be implemented if needed.

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 the recommended action is applied. Further restrictions as deemed necessary based on the customer's security policies may be required during this interim period.
