Recommended Actions for System Products:
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-2011-0013
For CM 5.x, a workaround is to use the Web Access Mask page to only allow certain profiles access to the Avaya Installation Wizard (AIW) and Network Region Wizard (NRW) functionality.
Rated a None Risk for Session Manager since Tomcat is not accessible on the SM SIPAS container as http ports are not enabled.
Rated a Low Risk for all other products since Administrative privileges are required to exploit this vulnerability.
