****Description****

This advisory documents an internally found vulnerability in the on premises deployment model of Arista CloudVision Portal (CVP) where under a certain set of conditions, user passwords can be leaked in the Audit and System logs.

The impact of this vulnerability is that the CVP user login passwords might be leaked to other authenticated users.

While this advisory is similar to Arista Security Advisory 0045, it is different both in the underlying root cause and in that it discloses the passwords in the audit logs.

This issue is specific to using CVP user authentication via local (user accounts local to CVP application), TACACS or RADIUS, thus only applicable to the on-premises CloudVision Portal; CloudVision as-a-Service does not use these modes of authentication and is not affected by this issue.

This issue was discovered by an Arista customer and Arista is not aware of any malicious use of this issue in customer networks.
