At a glance
This record tracks a critical-severity Improper Restriction of Excessive Authentication Attempts vulnerability in the WPS Limit Login WordPress plugin, affecting versions < 1.4.6.1. It carries a CVSS score of 9.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires no authentication. The issue is fixed in version 1.4.6.1; sites on affected versions should update now. Disclosed July 2019, reported by Julio Potier.
Vulnerability Overview
The WPS Limit Login plugin for WordPress is vulnerable to authentication bypass in versions up to, and including, 1.4.6. This is due to flawed implementation of the get_address() method. This makes it possible for unauthenticated attackers to run automated scripts to brute force passwords by changing the supplied IP Address in the HTTP header of the request. .
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 confidentiality, integrity, availability — full site compromise territory.
CWE-307: Improper Restriction of Excessive Authentication Attempts
The product does not implement sufficient measures to prevent multiple failed authentication attempts within a short time frame.
Remediation
Update to version 1.4.6.1, or a newer patched version
How does WordSec protect against this?
The fix is the thing that ends this: WPS Limit Login 1.4.6.1 closes this, and updating the plugin is the step that ends it.
