CVE-2012-5325
At a glance
CVE-2012-5325 is a medium-severity Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in the Shortcode Redirect WordPress plugin, affecting versions <= 1.0.01. It carries a CVSS score of 5.4 (reachable over the network; low attack complexity). The issue is fixed in version 1.0.02; sites on affected versions should update now. Disclosed January 2012, reported by Gianluca Brindisi.
Vulnerability Overview
Multiple cross-site scripting (XSS) vulnerabilities in the scr_do_redirect function in scr.php in the Shortcode Redirect plugin 1.0.01 and earlier for WordPress allow remote authenticated users with certain permissions to inject arbitrary web script or HTML via the (1) url or (2) sec attributes in a redirect tag.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed.
CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Reaching this weakness in Shortcode Redirect <= 1.0.01 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 Shortcode Redirect the fix is 1.0.02: builds <= 1.0.01 are affected, anything from 1.0.02 onward is not.
Remediation
Update to version 1.0.02, or a newer patched version
How does WordSec protect against this?
The attempt arrives as an ordinary request to Shortcode Redirect: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Shortcode Redirect 1.0.02 closes this, and updating the plugin is the step that ends it.
