At a glance

This record tracks a critical-severity Missing Authorization vulnerability in the Real3D Flipbook WordPress plugin, affecting versions < 2.9. It carries a CVSS score of 10.0 (reachable over the network; low attack complexity; high integrity, availability impact). Exploitation requires no authentication. The issue is fixed in version 2.9; sites on affected versions should update now. Disclosed July 2016, reported by Mukarram Khalid.

Vulnerability Overview

The Real3D Flipbook plugin for WordPress is vulnerable to Unauthenticated File or Directory Delete in versions up to, and including, 2.8. This is due to missing privilege checks. This makes it possible for unauthenticated attackers to delete arbitrary files or folders on the site.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site, and no interaction from a victim user. A successful exploit has high impact on integrity, availability.

CWE-862: Missing Authorization

Reaching this weakness in Real3D Flipbook < 2.9 takes no account at all. A missing authorization check means a function is reachable by anyone who can reach the endpoint, because the code never asks whether the caller is allowed to perform the action.

Any user who can reach the endpoint gets to run an action reserved for higher-privileged roles, from reading protected data to changing settings or content. For Real3D Flipbook the fix is 2.9: builds < 2.9 are affected, anything from 2.9 onward is not.

Remediation

Update to version 2.9, or a newer patched version

How does WordSec protect against this?

This one needs no account at all, which puts it outside what login hardening can reach; WordSec's login security narrows the account-level paths around it, and the firewall is what inspects the request itself. None of that substitutes for the fix: Real3D Flipbook 2.9 closes this, and updating the plugin is the step that ends it.
