At a glance

CVE-2011-3128 is a medium-severity Exposure of Sensitive Information to an Unauthorized Actor vulnerability in the WordPress 3.1 WordPress release line, affecting <= 3.1.2. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). The issue is fixed in version 3.1.3; sites on affected versions should update now. Disclosed May 2011.

Vulnerability Overview

WordPress 3.1 before 3.1.3 and 3.2 before Beta 2 treats unattached attachments as published, which might allow remote attackers to obtain sensitive data via vectors related to wp-includes/post.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 interaction from a victim user.

CWE-200: Exposure of Sensitive Information to an Unauthorized Actor

Reaching this weakness in WordPress 3.1 <= 3.1.2 takes a caller who can reach the endpoint. Sensitive information exposure means data the application intended to keep internal is returned to a caller who should not be able to see it.

The disclosed data — credentials, tokens, customer records or internal paths — is usually worth more as material for a follow-up attack than as an end in itself. For WordPress 3.1 the fix is 3.1.3: builds <= 3.1.2 are affected, anything from 3.1.3 onward is not.

Remediation

Update to version 3.1.3, or a newer patched version
