Introduction

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 does not filter special characters (e.g. single quotes) from uploaded csv files.

More Details

In ./citrusdb/tools/importcc.php data from a previous uploaded csv file is inserted into the mysql database but none of the values is filtered.

Proof of Concept

A csv file with content

',,,,,

makes the SQL-Query in ./citrusdb/tools/importcc.php fail.

Workaround

Check csv files manually for single quotes before upload.

Fix

n/a

Security Risk

The security risk is rated low because only special users may upload csv files and with this SQL injection it is only possible to inject data that could be easier injected directly through csv file.
