At a glance
CVE-2015-5485 is a medium-severity Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in the The Events Calendar WordPress plugin, affecting versions < 3.10.2. 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 3.10.2; sites on affected versions should update now. Disclosed July 2015, reported by Mallory Adams.
Vulnerability Overview
Reflected Cross-site scripting (XSS) vulnerability in the Event Import page (import-eventbrite-events.php) in the Modern Tribe Eventbrite Tickets plugin before 3.10.2 for WordPress allows remote attackers to inject arbitrary web script or HTML via the "error" parameter to wp-admin/edit.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.
CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
The Events Calendar < 3.10.2 carries this weakness at error, and reaching it 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 The Events Calendar the fix is 3.10.2: builds < 3.10.2 are affected, anything from 3.10.2 onward is not.
Remediation
Update to version 3.10.2, or a newer patched version
How does WordSec protect against this?
The attempt arrives as an ordinary request to The Events Calendar: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: The Events Calendar 3.10.2 closes this, and updating the plugin is the step that ends it.
