What to do
Solution: This product is no longer supported and the issue will not be fixed. This issue can be easily mitigated by creating a "C:\proc" folder and not allowing unprivileged users to access to that folder, or ensuring unprivileged users do not have 'create folder' access to the root of a disk (C:\).
Workaround: Exploitation of this issue can be prevented by creating a "C:\proc" folder and not allowing unprivileged users to access that folder.
