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 IR | 4.0 | Low | IR does not use the Adobe Flash player for any functions and it's use is not supported. Avaya will not test any issues related to this alert since the software is not used by Avaya products. |
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-2011-2426 CVE-2011-2427 CVE-2011-2428 CVE-2011-2429 CVE-2011-2430 CVE-2011-2444 |
These are a Low risk as Adobe Flashplayer is installed but not used or configured by default. |
