2. Avaya System Products using a Solaris Operating System with SCTP installed:

Some Avaya system products are delivered with a Solaris Operating System. Actions to be taken on these products are described below.

Product: Affected Version(s): Risk Level: Actions:
Avaya CMS R15.0.x, R16.0, R16.1, R16.2 Medium CMS R15: Upgrade to CMS R15.0ab.k or later.
CMS R16: Upgrade to CMS R16.2da.h or later.
Avaya IR 3.0, 4.0 Low SCTP is not configured or supported. Therefore a patch will not be tested or approved.

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 products and the surrounding network from this potential vulnerability may be mitigated by ensuring these practices are implemented until such time as an Avaya provided product update or the recommended Avaya action is applied. Further restrictions as deemed necessary based on the customer's security policies may be required during this interim period, but customers should not modify the System Product operating system or application unless the change is approved by Avaya. Making changes that are not approved may void the Avaya product service contract.

Mitigating Factors:

When determining risk, Avaya takes into account many factors as outlined by Avaya's Security Vulnerability Classification Policy. The following table describes factors that mitigate the risk of specific vulnerabilities for affected Avaya products:

Vulnerability Mitigating Factors
CVE-2011-0820
This is rated a Low Risk for IR since SCTP is not configured or supported.
This is rated a Medium Risk for CMS since a local user can cause the system to become unavailable.
