Name of the Vulnerable Software and Affected Versions Integrity Protection Driver (IPD) versions 1.2 through 1.3

Description The issue allows local users to create and overwrite arbitrary files via a symlink attack on winntsystem32drivers using the subst command. This is due to a flaw in the NtCreateSymbolicLinkObject function in ntdll.dll.

Recommendations For Integrity Protection Driver (IPD) versions 1.2 through 1.3, as a temporary workaround, consider restricting access to the subst command and the winntsystem32drivers path to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
