The Inventory module of the 1E Client 5.0.0.745 doesn't handle an unquoted path when executing %PROGRAMFILES%\1E\Client\Tachyon.Performance.Metrics.exe. This may allow remote authenticated users and local users to gain elevated privileges.
The product uses a search path that contains an unquoted element, in which the element contains whitespace or other separators. This can cause the product to access resources in a parent path.
