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 | R16, R16.1, R16.2, R15.x | Medium | CMS R16, R16.1, R16.2 upgrade to CMS R16.3 or later. CMS R15 upgrade to CMS R15ab.m or R15auxab.m or later. |
| Avaya IR | 4.0 | Medium | Upgrade to IR 4.0 Service Pack 6 and install "Solaris 10 Patch Cluster (Jan 2012) for Avaya IR 4.0 Service Pack 6" or later. |
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.
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-2011-3515 CVE-2011-3537 CVE-2011-2286 CVE-2011-3534 CVE-2011-3535 CVE-2011-3536 CVE-2011-2311 CVE-2011-2312 CVE-2011-2313 |
These are a medium risk for IR and CMS due to the potential for a user to cause a Denial of Service or escalate their privileges. |
|
CVE-2011-3508 |
This is a low risk for CMS and IR as the affected package is installed but not used by default. |
|
CVE-2011-2304 |
This is a low risk for CMS and IR as no critical system processes or applications would be affected. |
|
CVE-2011-3542 CVE-2011-2292 CVE-2011-3539 |
These are no risk for CMS and IR as Solaris 9, Solaris 10 x86 and zones are not used or supported by default. |
