At a glance

CVE-2015-2084 is a high-severity Cross-Site Request Forgery (CSRF) vulnerability in the Easy Social Icons WordPress plugin, affecting versions <= 1.2.2. It carries a CVSS score of 8.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires no authentication. The issue is fixed in version 1.2.3; sites on affected versions should update now. Disclosed February 2015, reported by Eric Flokstra - ITsec Security Services.

Vulnerability Overview

Cross-site request forgery (CSRF) vulnerability in the Easy Social Icons plugin before 1.2.3 for WordPress allows remote attackers to hijack the authentication of administrators for requests that conduct cross-site scripting (XSS) attacks via the image_file parameter in an edit action in the cnss_social_icon_add page to wp-admin/admin.php.

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. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.

CWE-352: Cross-Site Request Forgery (CSRF)

Reaching this weakness in Easy Social Icons <= 1.2.2 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 Easy Social Icons the fix is 1.2.3: builds <= 1.2.2 are affected, anything from 1.2.3 onward is not.

Remediation

Update to version 1.2.3, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Easy Social Icons: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Easy Social Icons 1.2.3 closes this, and updating the plugin is the step that ends it.
