- Force the administrator to change the credential upon installation.
- The product administrator could change the defaults upon installation or during operation.
Timeline
- CVE record published.
- CISA published its SSVC assessment (exploitation: none, automatable: no, technical impact: total).
- Record last changed materially (score, affected products, status or references).
