• localized privilege escalation
• potential for lateral movement
• need for verification of affected versions
• requirement for upgrading to patched versions

Technical summary

The vulnerability exists in the account management interface of Brocade Fabric OS versions before 9.2.2d and 10.0.0 through 10.0.0a1. An authenticated user can bypass authorization restrictions intended to prevent modifying another account's access privileges, allowing a lower-privileged user to assign administrative roles to a target account, leading to localized privilege escalation. This can be mitigated by verifying and upgrading to patched versions, restricting access, and monitoring for suspicious activity. Defenders should prioritize verifying affected scope and vendor guidance.
