At a glance

This record tracks a medium-severity Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in the Photo Gallery by 10Web WordPress plugin, affecting versions < 1.3.43. It carries a CVSS score of 4.1 (reachable over the network; low attack complexity). Exploitation requires an authenticated account. The issue is fixed in version 1.3.43; sites on affected versions should update now. Disclosed June 2017, reported by Mallory Adams.

Vulnerability Overview

The Photo Gallery by 10Web plugin for WordPress is vulnerable to Path Traversal in versions up to, and including, 1.3.42. This allows administrative-level attackers to read the contents of arbitrary files on the server, which can contain sensitive 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-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

Reaching this weakness in Photo Gallery by 10Web < 1.3.43 takes any authenticated account. Path traversal happens when user-controlled text is used to build a filesystem path without being constrained to an intended directory, so sequences like ../ walk the resolved path somewhere else.

Depending on the operation, it means reading files outside the intended folder — wp-config.php being the usual target — or writing to and deleting paths the web server can touch. For Photo Gallery by 10Web the fix is 1.3.43: builds < 1.3.43 are affected, anything from 1.3.43 onward is not.

Remediation

Update to version 1.3.43, 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. None of that substitutes for the fix: Photo Gallery by 10Web 1.3.43 closes this, and updating the plugin is the step that ends it.
