Workarounds and Mitigations

This security exposure occurs only at installation time and does not affect already installed Administration Centers.

To prevent exposure to this security vulnerability, download and run the installation package from a clean directory using the following steps:

  1. As an administrator, create a new secure directory. The directory must not exist before and only the administrator should have write permission to it.
  2. Unzip or copy the files from your installation media into this new directory.
  3. Run the installation exe from this directory to install the product. Proceed with the installation as normal.

If installation of an Administration Center package below the fixing level (6.3.6) or installation of a package for release 6.2 or below is required, then the above workaround should be used to avoid exposure to this vulnerability during the installation process. The workaround is not needed if the fixing level (6.3.6) or a higher level of the package is installed.
