Summary

Brocade Fabric OS versions before 9.2.2d and 10.0.0 through 10.0.0a1 have a missing authentication flaw (CWE-306) in the web management daemon. The daemon registers session structures received over local inter-process communication without verifying the sending process. A local user with low privileges can gain administrative privileges on the web management interface without authenticating.

Description from the CNA

A session context forgery vulnerability exists in the web management daemon of Brocade Fabric OS versions 9.2.2d and 10.0.0 through 10.0.0a1. When processing local inter-process communication (IPC) storage callbacks, the service accepts and registers session structures including administrative role permissions, user identifiers, and authorization flags—without verifying the identity or authenticity of the sending process. An attacker can obtain elevated administrative privileges on the web management interface without legitimate authentication.
