CVE-2024-29953Network attack vector

Authenticated password disclosure via shared session storage

Published Jun 25, 2024 · Updated Aug 22, 2024

Information disclosure in Brocade Fabric OS before 9.2.1, 9.2.0b, and 9.1.1d allows remote authenticated users to read encoded passwords. On Virtual Fabric platforms, the web interface places encoded session passwords in session storage where other authenticated users can view them. Access requires valid credentials and a Virtual Fabric platform, and the disclosure does not grant data modification or service interruption.
