For the fresh install scenario, the fix allows the user to configure WebReports to use HTTPS at installation time. This fix has been applied to 9.5 (9.5.2).

For the existing installation scenario, instructions are provided to manually configure it.

Considering that the fresh installation scenario doesn't apply to 9.0, 9.1 and 9.2, for these releases instructions are provided to configure the check. Existing 9.5 installations can also configure the fix as per below.

BigFix 9.5 (new install):

To remediate this vulnerability when doing a fresh install, please use BigFix 9.5.2 or greater and you will see messages allowing the choice to set up HTTPS for WebReports.
