CVE-2013-3254 is a medium-severity Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in the WP Photo Album Plus WordPress plugin, affecting versions < 5.0.3.

The issue is fixed in version 5.0.3; sites on affected versions should update now. Disclosed May 2013, reported by Charlie Eriksen.

Vulnerability Overview

Cross-site scripting (XSS) vulnerability in wp-admin/admin.php in the WP Photo Album Plus plugin before 5.0.3 for WordPress allows remote attackers to inject arbitrary web script or HTML via the commentid parameter in a wppa_manage_comments edit action.

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 WP Photo Album Plus < 5.0.3 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 WP Photo Album Plus the fix is 5.0.3: builds < 5.0.3 are affected, anything from 5.0.3 onward is not.

Remediation

Update to version 5.0.3, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to WP Photo Album Plus: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: WP Photo Album Plus 5.0.3 closes this, and updating the plugin is the step that ends it.
