Netscape Enterprise Server Directory Indexing Vulnerability
The Directory Indexing feature can be turned off via the Administration Interface. Selecting Content Management -> Document Preferences and changing Directory Indexing to "none" will disable this feature.
Also, manually editing the file obj.conf will do the same. Conduct a search for the following:
Service method="(GET|HEAD)" type="magnus-internal/directory"
and replace fn="index-common" with fn="send-error".
