Credit Card data disclosure in CitrusDB

RedTeam found an information disclosure vulnerability in CitrusDB which can result in disclosure of credit card information.


  • Product: CitrusDB
  • Affected Version: <= 0.3.5
  • Immune Version: >=0.3.6
  • OS affected: all
  • Security-Risk: very high
  • Remote-Exploit: yes
  • Vendor-URL:
  • Vendor-Status: informed, new version released
  • Advisory-URL:
  • CVE: CAN-2005-0229 (


Description from vendor:

“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.

More Details

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.

Proof of Concept

Add “/citrusdb/io/newfile.txt” to the URL of a site running CitrusDB default installation.


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.


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

Security Risk

The software is still beta, so it probably isn’t widely used. To sites running CitrusDB, the risk is very high because credit card data is concerned. Disclosure of credit card data can lead to serious liability issues for the site.
