At a glance

CVE-2022-41155 is a medium-severity Authentication Bypass by Primary Weakness vulnerability in the iQ Block Country WordPress plugin, affecting versions <= 1.2.18. It carries a CVSS score of 5.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 1.2.19; sites on affected versions should update now. Disclosed September 2022.

Vulnerability Overview

The iQ Block Country plugin for WordPress is vulnerable to Country Blocking Bypass in versions up to, and including, 1.2.18. This is due to the improperly implemented login page verification check in the iqblockcountry_is_login_page function. This makes it possible for unauthenticated attackers to bypass the country block by including the string 'wp-login' in the URL.

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.

CWE-305: Authentication Bypass by Primary Weakness

The authentication algorithm is sound, but the implemented mechanism can be bypassed as the result of a separate weakness that is primary to the authentication error.

Remediation

Update to version 1.2.19, 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: iQ Block Country 1.2.19 closes this, and updating the plugin is the step that ends it.
