At a glance
This record tracks a medium-severity Insertion of Sensitive Information into Log File vulnerability in the UpdraftPlus WordPress plugin, affecting versions <= 1.22.24. It carries a CVSS score of 5.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 1.23.1; sites on affected versions should update now. Disclosed March 2023.
Vulnerability Overview
The Updraft Plus plugin for WordPress is vulnerable to information disclosure in versions up to, and including, 1.22.24. This is due to the fact that the 'updraft_ajaxrestore' function generates a log file containing system configuration information. This makes it possible for unauthenticated attackers to trigger generation of such a log file, though it is only possible to access it on configurations that do not respect the "deny from all" directive.
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.
CWE-532: Insertion of Sensitive Information into Log File
The product writes sensitive information to a log file.
Remediation
Update to version 1.23.1, or a newer patched version
How does WordSec protect against this?
The fix is the thing that ends this: UpdraftPlus 1.23.1 closes this, and updating the plugin is the step that ends it.
