OS Command Injection in Fabric OS Account Management

Published Oct 8, 2026 CVSS 4.0 · 5.4 Medium EPSS < 1% KEV · Not listed
Description
An OS command injection vulnerability exists in the account management subsystem of Brocade Fabric OS versions before 9.2.2d and 10.0.0 through 10.0.0a1. When an administrator initiates an account deletion, the system invokes an internal maintenance routine to clean up cryptographic keys associated with the target account. Malformed account names previously accepted by Fabric OS can cause the execution of embedded shell metacharacters, triggering command injection.
