At a glance
CVE-2015-9322 is a high-severity Cross-Site Request Forgery (CSRF) vulnerability in the Erident Custom Login and Dashboard WordPress plugin, affecting versions <= 3.4.1. 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 3.5; sites on affected versions should update now. Disclosed June 2015, reported by James Hooker.
Vulnerability Overview
The Erident Custom Login and Dashboard plugin for WordPress is vulnerable to Cross-Site Request Forgery to Stored Cross-Site Scripting via the ‘er_options_up[dashboard_data_left]’ parameter in versions up to, and including, 3.4.1 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
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)
Erident Custom Login and Dashboard <= 3.4.1 carries this weakness at er_options_up[dashboard_data_left], and reaching it 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 Erident Custom Login and Dashboard the fix is 3.5: builds <= 3.4.1 are affected, anything from 3.5 onward is not.
Remediation
Update to version 3.5, or a newer patched version
How does WordSec protect against this?
The attempt arrives as an ordinary request to Erident Custom Login and Dashboard: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Erident Custom Login and Dashboard 3.5 closes this, and updating the plugin is the step that ends it.
