Unauthorized access via unrestricted authentication attempts
Published Dec 5, 2025 · Updated Dec 5, 2025
Improper authentication-attempt restriction in Dell CloudBoost Virtual Appliance before 19.13.0.2 allows remote attackers unauthorized access. Dell identifies proprietary authentication code but has not disclosed the affected endpoint or how failed attempts evade restriction. Exploitation requires unauthenticated network access and high attack complexity; successful access can affect confidentiality, integrity, and availability.
