At a glance

CVE-2019-14798 is a medium-severity Improper Control of Filename for Include/Require Statement in PHP Program ('PHP Remote File Inclusion') vulnerability in the Photo Gallery by 10Web WordPress plugin, affecting versions <= 1.5.24. It carries a CVSS score of 4.9 (reachable over the network; low attack complexity; high confidentiality impact). Exploitation requires an authenticated account. The issue is fixed in version 1.5.25; sites on affected versions should update now. Disclosed May 2019.

Vulnerability Overview

The 10Web Photo Gallery plugin before 1.5.25 for WordPress has Authenticated Local File Inclusion via directory traversal in the wp-admin/admin-ajax.php?action=shortcode_bwg tagtext parameter.

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. A successful exploit has high impact on confidentiality.

CWE-98: Improper Control of Filename for Include/Require Statement in PHP Program ('PHP Remote File Inclusion')

Reaching this weakness in Photo Gallery by 10Web <= 1.5.24 takes any authenticated account. PHP file inclusion means a path used by include or require is built from request data, so the file that gets executed is under the caller's influence.

Including an attacker-influenced file executes its contents, which is why this class is routinely chained with an upload or log-poisoning step to reach code execution. For Photo Gallery by 10Web the fix is 1.5.25: builds <= 1.5.24 are affected, anything from 1.5.25 onward is not.

Remediation

Update to version 1.5.25, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Photo Gallery by 10Web: WordSec's web application firewall inspects request payloads before WordPress loads them. Classes like this one can leave something behind, so the staged malware scanner is the second half: it looks for dropped files and modified code rather than for the request that created them. None of that substitutes for the fix: Photo Gallery by 10Web 1.5.25 closes this, and updating the plugin is the step that ends it.
