| Description |
|---|
| Enumeration techniques, such as URL parameter manipulation, rely on being able to obtain information about the web server's directory structure by locating directories without default pages. In this scenario, the web server will display to the user a listing of the files in the directory being accessed. By having a default hosted application web page, the anonymous web user will not obtain directory browsing information or an error message that reveals the server type and version. Ensuring that every document directory has an "index.jsp" (or equivalent) file is one approach to mitigating the vulnerability. |
