Workarounds and Mitigations

Follow the below steps to workaround the InstallAnywhere vulnerability.

Install the fix pack by running the installation wizard or by running a
silent installation:

To avoid an untrusted search path vulnerability where users could gain
increased privileges, perform the following additional steps:

1) Create a new, empty secure directory in a temporary location.

The directory must not exist before and only the administrator should have
write permission to it.

2) Copy or move the installer executable to the new, otherwise empty folder
created in Step 1.

3) Ensure there are no DLL files in this directory

4) Launch the installer executable from its new location.

Important: Do not enter line breaks in the command that you enter to start
the installation program.
