Name of the Vulnerable Software and Affected Versions: Brocade Fabric OS versions 9.0.0 through 9.2.2

Description: The issue is related to an Improper Check for Unusual or Exceptional Conditions, which could allow an authenticated, network-based attacker to cause a Denial-of-Service (DoS). This occurs when supportsave is invoked remotely using ssh command or SANnav inline ssh, and the corresponding ssh session is terminated with Control C (^c) before supportsave completion.

Recommendations: For Brocade Fabric OS versions 9.0.0 through 9.2.2, update to version 9.2.2.a or later to resolve the issue. As a temporary workaround, consider avoiding the use of supportsave invoked remotely until a patch is available. Restrict access to ssh sessions to minimize the risk of exploitation.
