The files can be accessed via directory traversal, i.e., by entering a .. (dot dot) path such as ..\\..\\..\\..\\..\\<file> in the input field of the FileEditor. In FlexDotnetCMS before v1.5.8, it is also possible to access files by specifying the full path (e.g., C:\\<file>). The files can then be edited via the FileEditor."
