At a glance
This record tracks a medium-severity Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in the Wp-ImageZoom WordPress plugin, affecting versions < 1.0.5. 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 1.0.5; sites on affected versions should update now. Disclosed June 2012, reported by Sammy Forgit.
Vulnerability Overview
The Wp-ImageZoom plugin for WordPress is vulnerable to Directory Traversal in versions before 1.0.5 via the 'file' parameter. This allows 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 privileges on the target site, and no interaction from a victim user.
CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Wp-ImageZoom < 1.0.5 carries this weakness at file, and reaching it takes a caller who can reach the endpoint. 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 Wp-ImageZoom the fix is 1.0.5: builds < 1.0.5 are affected, anything from 1.0.5 onward is not.
Remediation
Update to version 1.0.5, or a newer patched version
How does WordSec protect against this?
The attempt arrives as an ordinary request to Wp-ImageZoom: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Wp-ImageZoom 1.0.5 closes this, and updating the plugin is the step that ends it.
