Short explanation
Supermicro BMC iKVM feature is vulnerable to KVM session hijacking due to a predictable time-seeded launch token (S0). The HTML5 KVM-over-IP console authenticates with a token returned by the web interface (S0).
Weaknesses in token generation may allow an attacker to guess the session token and take control of the KVM session (S0). This introduces risks of unauthorized access on affected targets.
What should be done?
- Follow the vendor security advisory
- Check official sources for updates
- Follow vendor recommendations given the UNKNOWN patch status
