Identify CVE-2022-27509 impacted instances
CVE-2022-27509 requires a combination of custom scan and version scan. As part of the custom scan, ADM service connects with the managed ADC instance and pushes a script to the instance. The script runs on the ADC instance and determines if the instance is vulnerable. This script runs every time your scheduled or on-demand scan runs.
After the scan is completed, the script is deleted from the ADC instance.
