Vulnerability Overview

The Service Finder - Provider and Business Listing theme for WordPress is vulnerable to Path Traversal in versions up to 3.2 via the 'file' parameter found in the downloads.php file. This allows unauthenticated attackers to read the contents of arbitrary files on the server, which can contain sensitive information.

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')

Service Finder - Provider and Business Listing WordPress Theme < 3.2 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 Service Finder - Provider and Business Listing WordPress Theme the fix is 3.2: builds < 3.2 are affected, anything from 3.2 onward is not.

Remediation

Update to version 3.2, or a newer patched version
