Privileged array access via unintended authentication method
Published Jul 17, 2024 · Updated Apr 10, 2025
Authentication bypass in Pure Storage FlashBlade allows remote attackers to gain privileged array access through a local account. The management interface accepts authentication for a local account through an unintended method; Pure Storage has not disclosed that method's request or validation details. Network access to the management interface and an existing local account are required, but the published vector indicates that no prior authenticated session is needed.
