What it is
Input is written into a web page without escaping, so an attacker's script runs in the browser of anyone who views it.
How it is reached
An attacker can exploit it over the network, with an administrator account, but someone has to act first, such as opening a file or following a link.
What an attacker gains
A successful attack can read the data it protects, change data or behaviour and take it offline. In practice, this kind of flaw lets an attacker act inside a signed-in user's browser session.
Is it being exploited?
There is no public report of exploitation yet.
What to do
- Upgrade ShopEngine Gutenberg WooCommerce Builder Blocks Addon to 2.4.4 or later.
- Until it is patched, review who holds accounts that can reach it.
- Warn the people who use it, and filter files and links on the way in.
Description from NVD
The ShopEngine Gutenberg WooCommerce Builder Blocks Addon WordPress plugin before 2.4.4 does not validate the user's capabilities or the ownership of the targeted post in one of its AJAX actions, and does not escape the stored value before outputting it in a JavaScript context, allowing users with a role as low as contributor to inject arbitrary scripts into any post that will run when a higher privileged user edits it.
What this means for your architecture.
A CVE names a product. Whether it matters depends on where that product sits in your systems: what reaches it, which trust boundary it guards and what it can reach once compromised. Veriom maps your components, their relationships and your trust boundaries from your code, cloud and delivery evidence, so you can see where a component like this sits. The radar itself does not look at your systems.
Components it touches
- WordPress sites and their plugins. Plugins run inside the site with its database access, and many sites are public.
- Web front ends and single-page apps. The flaw sits between a user's browser and the web application.
- Admin consoles served to a browser. The flaw sits between a user's browser and the web application.
Trust boundaries in play
- Authenticated network access. An account is needed, so exposure follows who can sign in: customers, partners or staff.
- People who open files and links. Mail, chat and browsers are the delivery path.
- Between a user's browser and the web application. An attacker who crosses it can act inside a signed-in user's browser session.
