At a glance
This record tracks a high-severity Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in the Javo Spot - Multi Purpose Directory WordPress Theme WordPress theme, affecting versions < 3.0.0. It carries a CVSS score of 7.5 (reachable over the network; low attack complexity; high confidentiality impact). Exploitation requires no authentication. The issue is fixed in version 3.0.0; sites on affected versions should update now. Disclosed February 2017, reported by soulseekah.
Vulnerability Overview
The Javo Spot theme for WordPress is vulnerable to Directory Traversal in versions up to 3.0.0 via the 'fn' parameter found in the jvfrm_spot_get_json() function called via a nopriv AJAX action. This makes it possible for unauthenticated 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. A successful exploit has high impact on confidentiality.
CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Javo Spot - Multi Purpose Directory WordPress Theme < 3.0.0 carries this weakness at jvfrm_spot_get_json(), 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 Javo Spot - Multi Purpose Directory WordPress Theme the fix is 3.0.0: builds < 3.0.0 are affected, anything from 3.0.0 onward is not.
Remediation
Update to version 3.0.0, or a newer patched version
How does WordSec protect against this?
The attempt arrives as an ordinary request to Javo Spot - Multi Purpose Directory WordPress Theme: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Javo Spot - Multi Purpose Directory WordPress Theme 3.0.0 closes this, and updating the theme is the step that ends it.
