At a glance

CVE-2020-35234 is a high-severity Insertion of Sensitive Information into Log File vulnerability in the Easy WP SMTP WordPress plugin, affecting versions <= 1.4.2. It carries a CVSS score of 8.1 (reachable over the network; high confidentiality, integrity, availability impact). Exploitation requires no authentication. The issue is fixed in version 1.4.3; sites on affected versions should update now. Disclosed December 2020.

Vulnerability Overview

The easy-wp-smtp plugin before 1.4.4 for WordPress allows Administrator account takeover, as exploited in the wild in December 2020. If an attacker can list the wp-content/plugins/easy-wp-smtp/ directory, then they can discover a log file (such as #############_debug_log.txt) that contains all password-reset links. The attacker can request a reset of the Administrator password and then use a link found there.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, and no privileges on the target site, and no interaction from a victim user. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.

CWE-532: Insertion of Sensitive Information into Log File

The product writes sensitive information to a log file.

Remediation

Update to version 1.4.3, or a newer patched version

How does WordSec protect against this?

The fix is the thing that ends this: Easy WP SMTP 1.4.3 closes this, and updating the plugin is the step that ends it.
