What it is

Files of dangerous types can be uploaded, and the server may run or serve them.

How it is reached

An attacker can exploit it over the network, with an ordinary user account, and nobody has to click anything.

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 place a file the server will run or serve to others.

Is it being exploited?

There is no public report of exploitation yet.

Description from NVD

The Interactive Real Estate – Floor Plan & Building Visualizer plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to, and including, 2.6.0 via the extract_zip_data function. This is due to missing capability check, nonce verification, and file extension or MIME type validation before copying attacker-supplied ZIP members to the uploads directory. This makes it possible for authenticated attackers, with subscriber-level access and above, to upload files that may be executable, which makes remote code execution possible. This vulnerability is only exploitable on sites where the plugin's Freemius Premium license or trial is active, as the sole gate in the handler is a site-level license check rather than a per-user capability check.

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.
Upload endpoints and the storage behind them. The flaw sits between uploaded content and the servers that store or serve it.

Trust boundaries in play

Authenticated network access. An account is needed, so exposure follows who can sign in: customers, partners or staff.
Between uploaded content and the servers that store or serve it. An attacker who crosses it can place a file the server will run or serve to others.
