This template is intended to be used to document the outcome of the impact analysis related to the known vulnerability reported by Nexus-IQ (CLM tab in Jenkins). Nexus-IQ can identify the known vulnerabilities contained in the components use by onap components.
This table will be presented to TSC at Code Freeze milestone (M4) to the TSC.
It is recommended to first update to the latest version of the third party components available. In case the latest third party components still reports some vulnerabilities, you must provide an impact analysis as illustrated in the example below.
In the case where you have nested third party components (a third party component embedding another third party component) and there is NO CVE number for the upstream third party component (meaning the third party component you are embedding), it is recommended to open a vulnerability issue on the upstream third party component.
The following table is addressing 2 different scenarios:
- Confirmation of a vulnerability including an action
- False Positive
