Good morning,
Could You also add the cpe "cisco:identity_services_engine" to the CVE since Cisco Identity Services Engine Software and Cisco Identity Services Engine are two different names for the same product?
We would appreciate it very much.
The others CVEs are:
CVE-2023-20175
CVE-2023-20195
CVE-2023-20196
CVE-2023-20213
