The underlying weakness: Weak Password Requirements
The product does not require that users should have strong passwords.
How developers prevent this class of flaw
- Consider a second authentication factor beyond the password, which prevents the password from being a single point of failure. See CWE-308 for further information.
- Consider implementing a password complexity meter to inform users when a chosen password meets the required attributes.
Timeline
- CVE record published.
- CISA published its SSVC assessment (exploitation: poc, automatable: no, technical impact: total).
- Record last changed materially (score, affected products, status or references).
