This week, PHP safety organization RIPS Technologies published the studies that led to this warning which gives WooCommerce and WordPress admins extra of the gory detail.

There are elements to the vulnerability, the first of which the researchers describe as a “layout flaw in the privilege system of WordPress.”

The second, in WooCommerce itself, is a reputedly easy record deletion vulnerability affecting variations 3.4. Five and in advance.

Which of the 2 is the larger issue will rely upon whether or not you worry more approximately a site’s e-commerce feature or show up to be its admin – both manner, the aggregate spells trouble.

After gaining get admission to thru a phishing assault or as an internal process, an attacker could use a weak spot inside the log file deletion routine to delete woocommerce.Php, taking down the website and inflicting WordPress to disable the plugin.

This, RIPS Technologies researcher Simon Scannell discovered, might be enough for any WooCommerce person with a Shop Manager account and an information of what they’d just executed to compromise the entire web page.

But how?

When WooCommerce is installed, the Shop Manager role is assigned the robust edit_users capability needed to edit purchaser debts, that’s saved with the aid of WordPress itself.

Because this will be used to edit the WordPress web site’s admin account too, its scope is restricted by way of a unique WooCommerce ‘meta capability’ filter out.

Unfortunately, for WordPress to use this shield the plugin wishes to be energetic – which it wouldn’t be if an attacker has exploited the WooCommerce document deletion weakness.

Writes Scannell:

The meta privilege test which restricts shop managers from editing administrators might not execute and the default conduct of allowing users with edit_users to edit any user, even directors, could occur.

The WooCommerce account with Shop Manager privileges would then be capable of raise those to alternate the site’s password and with it control of the entire web page.

What to do
On the WooCommerce side, ensure it’s been upgraded to model three.Four.6, which regarded on eleven October. Plugins aren’t up to date by using the default, which means that admins will need to initiate this for themselves through the wp-admin dashboard/plugins sidebar.

As for the WooCommerce fix:

With this release, Shop Managers can handiest edit customers with the Customer position by means of default, and there’s a whitelist of roles that Shop Managers can edit.

Redesigning the manner the WordPress permission system interacts with plugins would possibly take a little longer.

For motives as long as your arm, plugins have always been WordPress’s underbelly. The TL;DR is they want regular tending as does the platform itself – by no means take both without any consideration.
