A vulnerability in the Transport Layer Security (TLS) and Secure Sockets Layer (SSL) protocols has been discovered which could allow someone to inject themselves into an authenticated TLS/SSL communications path as part of a man-in-the-middle attack. This would allow an attacker to inject arbitrary content as the client, which would then be treated by the server as if the data was from the client. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2009-3555 to this issue.
More information about this vulnerability may be found on the following sites:
Various Avaya system products are vulnerable, as they use TLS/SSL in components such as Web services, VoIP communication and other services. Due to the limited conditions that must exist for this issue to be taken advantage of, Avaya has classified this as a Low risk vulnerability.
This advisory has been updated with links to existing Avaya Security Advisories that cover Operating System and third party vendor fixes to TLS/SSL services utilized by Avaya products. Since this vulnerability is at the protocol level, affected Avaya products will continue to update any fixed TLS/SSL libraries as they become available from Operating System and third party vendors. Please refer to new Avaya Security Advisories covering related TLS/SSL vulnerabilities should they be released in the future.

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'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 is available. Further restrictions as deemed necessary based on the customer's security policies may be required during this interim period.
Avaya Security Advisories covering System Products affected by TLS/SSL renegotiation vulnerabilities (as of January 4th, 2011) are:
Avaya software-only products operate on general-purpose operating systems. Occasionally vulnerabilities may be discovered in the underlying operating system or applications that come with the operating system. These vulnerabilities often do not impact the software-only product directly but may threaten the integrity of the underlying platform.
