The underlying weakness: Exposure of Information Through Directory Listing
The product inappropriately exposes a directory listing with an index of all the resources located inside of the directory.
How developers prevent this class of flaw
- Recommendations include restricting access to important directories or files by adopting a need to know requirement for both the document and server root, and turning off features such as Automatic Directory Listings that could expose private files and provide information that could be utilized by an attacker when formulating or conducting an attack.
