This record tracks a medium-severity Cross-Site Request Forgery (CSRF) vulnerability in the ALO EasyMail Newsletter WordPress plugin, affecting versions < 2.7.0. It carries a CVSS score of 5.7 (reachable over the network; low attack complexity; high integrity impact). The issue is fixed in version 2.7.0; sites on affected versions should update now. Disclosed February 2016, reported by Mohsen Lotfi.
Vulnerability Overview
The ALO EasyMail Newsletter plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 2.6.01. This is due to missing or incorrect nonce validation. This makes it possible for unauthenticated attackers to insert malicious code using a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed. A successful exploit has high impact on integrity.
CWE-352: Cross-Site Request Forgery (CSRF)
Reaching this weakness in ALO EasyMail Newsletter < 2.7.0 takes a caller who can reach the endpoint. Cross-site request forgery abuses the fact that browsers attach a victim's cookies to any request, so a state-changing action that only checks who you are, not whether you meant to act, can be triggered from another site.
An attacker who gets a logged-in user to load a crafted page can perform that action as them, with the impact scaling to whatever the victim's role is allowed to do. For ALO EasyMail Newsletter the fix is 2.7.0: builds < 2.7.0 are affected, anything from 2.7.0 onward is not.
Remediation
Update to version 2.7.0, or a newer patched version
How does WordSec protect against this?
The attempt arrives as an ordinary request to ALO EasyMail Newsletter: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: ALO EasyMail Newsletter 2.7.0 closes this, and updating the plugin is the step that ends it.
