At a glance

CVE-2013-4954 is a medium-severity Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in the Pie Register WordPress plugin, affecting versions <= 1.30. It carries a CVSS score of 6.1 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 1.31; sites on affected versions should update now. Disclosed August 2014.

Vulnerability Overview

Multiple cross-site scripting (XSS) vulnerabilities in wp-login.php in the Genetech Solutions Pie-Register plugin before 1.31 for WordPress, when "Allow New Registrations to set their own Password" is enabled, allow remote attackers to inject arbitrary web script or HTML via the (1) pass1 or (2) pass2 parameter in a register action. NOTE: some of these details are obtained from third party information.

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.

CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

Reaching this weakness in Pie Register <= 1.30 takes a caller who can reach the endpoint. Cross-site scripting happens when input from a request is written into a page without being escaped for the context it lands in, so the browser parses attacker-supplied text as markup or script.

Injected script runs with the privileges of whoever views the affected page, which is how these flaws turn into administrator session theft, silent account creation or persistent backdoors in page content. For Pie Register the fix is 1.31: builds <= 1.30 are affected, anything from 1.31 onward is not.

Remediation

Update to version 1.31, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Pie Register: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Pie Register 1.31 closes this, and updating the plugin is the step that ends it.
