For assessment and severity classification details refer to Section 3 of Avaya's Product Vulnerability Response Policy.
The "Resolution" column will be updated as fixes are made available. Please reference the "Information" column for any additional information regarding the affected product.
| Product: | Version(s): | Resolution: | Information: |
|---|---|---|---|
| Avaya Aura® Experience Portal | 8.x | Install the latest 8.0.x Security Updates. | 8.0.x Security Updates |
Recommended Actions for Products:
Avaya strongly recommends following 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 the System Product operating system or
application should not be modified unless the change is
approved by Avaya. Making changes that are not approved may
void the Avaya product service contract.
Avaya uses the Common Vulnerability Scoring System
(CVSS) base score and metrics as reported by the vendor for the affected component(s) or by the National Institute of Standards and Technology in the National Vulnerability Database. In some cases, such as where CVSS information is not available from the vendor or NIST, Avaya will calculate the CVSS base score and metrics. Customers are encouraged to calculate the Temporal and Environmental CVSS scores to determine how the vulnerability could affect their specific implementation or environment. For more information on CVSS and how the score is calculated, see
Common Vulnerability Scoring System: Specification Document.
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 may not impact the software-only product directly but may threaten the integrity of the underlying platform.
