Summary

In Brocade SANnav, before Brocade SANnav v2.3.0, syslog traffic was received in clear text. This could allow an unauthenticated, remote attacker to capture sensitive information.

Products Affected

  • Brocade SANNav before v2.3.0

Solution

A security update is provided in Brocade SANnav v2.3.0.

Notes

  • Brocade SANnav 2.3.0 and above uses secure syslog by default.
  • Brocade Fabric OS (FOS) v9.2.0 and above ensures secure Syslog by default.  
  • Prior versions of Brocade Fabric OS can be configured to enable secure syslog, but it is not enabled by default.
  • Brocade SANnav and Brocade Fabric OS must run versions supporting secure syslog. Otherwise, Brocade SANnav is registered in insecure mode.
