CVE-2024-29959Network attack vector

Encrypted switch-password disclosure via standby supportsave

Published Apr 19, 2024 · Updated Aug 2, 2024

Sensitive information exposure in Brocade SANnav before 2.3.1 and 2.3.0a allows remote attackers to read encrypted switch passwords. The standby component writes Brocade Fabric OS switch encrypted passwords into its supportsave archive instead of excluding the credential material. Exposure requires a standby node and access to its generated supportsave; the published impact is limited to password confidentiality.
