Summary

Brocade Fabric OS versions before 10.0.1 are affected. Input containing shell metacharacters reaches internal system execution wrappers during remote management connection validation and session verification for directory-based accounts, which is an OS command injection flaw (CWE-78). An authenticated user or a compromised directory service account can run arbitrary operating system commands with elevated privileges on the device.

Description from the CNA

Multiple OS Command Injection vulnerabilities exist in the management interface and session processing routines of Brocade Fabric OS versions before 10.0.1. Input processing flaws during remote management connection validation and session verification for directory-based user accounts allow untrusted input containing shell metacharacters to reach internal system execution wrappers. An authenticated user or a compromised directory service account can exploit these vulnerabilities to execute arbitrary operating system commands with elevated privileges on the target device.
