At a glance

This record tracks a high-severity Exposure of Sensitive Information to an Unauthorized Actor vulnerability in the Stream WordPress plugin, affecting versions <= 3.0.5. It carries a CVSS score of 7.5 (reachable over the network; low attack complexity; high confidentiality impact). Exploitation requires no authentication. The issue is fixed in version 3.0.6; sites on affected versions should update now. Disclosed May 2016, reported by James Golovich.

Vulnerability Overview

The Stream plugin for WordPress is vulnerable to Sensitive Data Exposure in versions up to, and including, 3.0.5. This can allow unauthenticated attackers to extract sensitive data including logged entries.

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, and no interaction from a victim user. A successful exploit has high impact on confidentiality.

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

Reaching this weakness in Stream <= 3.0.5 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 Stream the fix is 3.0.6: builds <= 3.0.5 are affected, anything from 3.0.6 onward is not.

Remediation

Update to version 3.0.6, or a newer patched version

How does WordSec protect against this?

The fix is the thing that ends this: Stream 3.0.6 closes this, and updating the plugin is the step that ends it.
