Credit Card Data Disclosure in CitrusDB
------------------------------------------------------------------------
SUMMARY
<http://www.citrusdb.org/> CitrusDB is "an open source customer database
application that uses PHP and a database backend (currently MySQL) to keep
track of customer information, services, products, billing, and customer
service information".
CitrusDB uses a textfile to temporarily store credit card information.
This textfile is located in the web tree via a static URL and thus
accessible to third parties. It also isn't deleted after processing
resulting in a big window of opportunity for an attacker..
DETAILS
Vulnerable Systems:
* CitrusDB version 0.3.5 and prior
Immune Systems:
* CitrusDB version 0.3.6 or newer
The URL to the textfile "<path to CitrusDB>/io/newfile.txt" is stated in
the files "tools/uploadcc.php" and "tools/importcc.php". The <path to
CitrusDB> is always known while surfing. Therefor also "newfile.txt"
containing the credit card data can be easily found and accessed. This
leads to disclosure of the confidential data stored in that file.
Workaround:
Either deny access to the file using access restriction features of your
webserver or change CitrusDB to use a file outside document root and not
accessible via HTTP.
Fix:
Update to CitrusDB version 0.3.6 or higher and set the $path_to_ccfile in
the configuration to a path not accessible via HTTP.
