While the architecture is simple to understand, it does not necessarily limit you to only simple problems. Your code is not required to have an object oriented architecture which makes the package usable by a larger audience. Further simplification happens by changing event handling from a callback-based model to a message passing one. The window definition is simplified by using Python core data types understood by beginners (lists and dictionaries). Transforms the tkinter, Qt, WxPython, and Remi (browser-based) GUI frameworks into a simpler interface. Stay tuned for more Simple Security Fail blog posts.9AF99B123C49D51EB547 click here to visit course page Implementing these changes to the web server can prevent a simple vulnerability from becoming a critical issue. htaccess file within the application directory Disable Directory Browsing from directory within the IIS manager console.The following steps can be performed to disable directory listing (browsing) on the web server: A great reference for additional search options is the Google Hacking Database. This technique can be used to discover specific files depending on the search made. Viewing one of these config.xml files – we can see reveals cleartext credentials for the backend database. Now let’s turn it up a notch – adding “config.xml” to the search and running it again results in some potentially sensitive config.xml files. Here are some example results of the search: Using Google to search for directory listings is pretty easy. Now let’s see if we can turn this simple issue into something more severe. DiscoveryĪs an example, the following screenshot shows what a directory listing might look like:Īs we can see, the web server is listing out the contents of the directory on the screen. However, occasionally we find this configuration enabled on some very sensitive directories indeed. Most of the time this issue comes up in reference to image directories which, from an attacker point of view, don’t usually provide much sensitive information. “Web servers can be configured to automatically list the contents of directories that do not have an index page present.” ( ). While performing security tests against web applications or network infrastructures, I often come across web servers with directory listing enabled.
