9.0.10 or 9.1.x prior to 9.1.3. It is, therefore, affected by an information exposure vulnerability where an
administrator's password or other sensitive information may be logged in cleartext while using the CLI. This is due to
the opcmdhistory.log file failing to mask all sensitive information.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
