Recently a security researcher sent us a CVE in our code where we are trying to use windows DeleteFileW and MoveFileW APIS and the researcher claims that they have scripts/code which can hijack the path sent to these APIs and replace them with symbolic links to windows system32 files or other sensitive files causing us to delete or move them. Our code runs as a privileged service and hence we need to prevent this kind of attack.
Since we are using Win32 APIs what is the best way forward? Our service needs to work on Win7 and above.
