At a glance

CVE-2014-3849 is a high-severity Missing Authorization vulnerability in the iMember360is WordPress plugin, affecting versions 3.8.012 – < 3.9.001. It carries a CVSS score of 7.5 (reachable over the network; low attack complexity; high availability impact). Exploitation requires no authentication. The issue is fixed in version 3.9.001; sites on affected versions should update now. Disclosed April 2014, reported by Everett Griffiths.

Vulnerability Overview

The iMember360 plugin 3.8.012 through 3.9.001 for WordPress does not properly restrict access, which allows remote attackers to delete arbitrary users via a request containing a user name in the Email parameter and the API key in the i4w_clearuser parameter.

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 availability.

CWE-862: Missing Authorization

Reaching this weakness in iMember360is 3.8.012 – < 3.9.001 takes a caller who can reach the endpoint. 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 iMember360is the fix is 3.9.001: builds 3.8.012 – < 3.9.001 are affected, anything from 3.9.001 onward is not.

Remediation

Update to version 3.9.001, or a newer patched version

How does WordSec protect against this?

Because it turns on account access, WordSec's login security is the relevant layer: role-based two-factor, captcha and brute-force limits raise the cost of getting the account this needs. None of that substitutes for the fix: iMember360is 3.9.001 closes this, and updating the plugin is the step that ends it.
