Overview
Full Path Disclose (AKA, FPD) vulnerabilities enable the attacker to see the path to the webroot/file. Eg: /home/omg/htdocs/file/. Certain vulnerabilities such as using the load_file() query to view page sources require the attacker to have the full path to the file they wish to view.
Severity
Low to Medium (circumstantial)
Exploit Likely-Hood
Extremely High
Examples
- Empty Array
If we have a site that uses a method of requesting a page like this:
http://site.com/index.php?page=about
We can use a method of opening and closing braces and causing the page to output an error. This method would look like this:
http://site.com/index.php?page[]=about
This renders the page defunct thus spitting out an error:
Warning: opendir(Array): failed to open dir: No such file or directory in /home/omg/htdocs/index.php on line 84 Warning: pg_num_rows(): supplied argument ... in /usr/home/example/html/pie/index.php on line 131
- Null Session Cookie
Another popular and very reliable method of producing errors containing a FPD is to give the page a nulled session using Javascript Injections. A simple injection using this method would look something like so:
javascript:void(document.cookie="PHPSESSID=");
