CVE-2024-43698Network attack vector

Unauthenticated administrator access via weak credentials

Published Oct 22, 2024 · Updated Oct 23, 2024

Weak credentials in Kieback&Peter DDC4000 controllers through affected releases allow remote attackers to gain full administrator rights. CISA identifies weak credentials as the defect but does not disclose their values, the affected interface, or the credential-validation path. Network reachability is sufficient, with no prior account or user interaction required; successful access grants complete administrative control.
