At a glance

CVE-2020-36668 is a medium-severity Exposure of Sensitive Information to an Unauthorized Actor vulnerability in the JetBackup WordPress plugin, affecting versions <= 1.4.0. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). The issue is fixed in version 1.4.1; sites on affected versions should update now. Disclosed July 2020, reported by Chloe Chamberland.

Vulnerability Overview

The JetBackup – WP Backup, Migrate & Restore plugin for WordPress is vulnerable to sensitive information disclosure in versions up to, and including, 1.4.0 due to a lack of proper capability checking on the backup_guard_get_manual_modal function called via an AJAX action. This makes it possible for subscriber-level attackers, and above, to invoke the function and obtain database table information.

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 JetBackup <= 1.4.0 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 JetBackup the fix is 1.4.1: builds <= 1.4.0 are affected, anything from 1.4.1 onward is not.

Remediation

Update to version 1.4.1, or a newer patched version

How does WordSec protect against this?

The fix is the thing that ends this: JetBackup 1.4.1 closes this, and updating the plugin is the step that ends it.
