DescriptionCVE.org

Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in vanquish WooCommerce Support Ticket System woocommerce-support-ticket-system allows Path Traversal.This issue affects WooCommerce Support Ticket System: from n/a through < 18.5.

AnalysisAI

A path traversal vulnerability exists in the Vanquish WooCommerce Support Ticket System plugin for WordPress, affecting all versions prior to 18.5, that allows attackers to access files outside the intended directory structure. The vulnerability is classified as CWE-22 (Improper Limitation of Pathname to Restricted Directory) and enables unauthorized file access or manipulation depending on the specific implementation context. While no CVSS score or EPSS data is currently available, and KEV status is unknown, the path traversal class of vulnerability typically carries significant risk in web applications where file operations are involved.

Technical ContextAI

The WooCommerce Support Ticket System plugin (CPE: cpe:2.3:a:vanquish:woocommerce_support_ticket_system:*:*:*:*:*:*:*:*) is a WordPress plugin that manages support ticket functionality for WooCommerce stores. The vulnerability stems from insufficient input validation on pathname parameters, which is the core issue described by CWE-22. This vulnerability class occurs when user-supplied input is used to construct file paths without proper sanitization, allowing attackers to use directory traversal sequences (such as '../' or '..\') to escape the intended directory boundaries and access arbitrary files on the server's filesystem. The affected versions range from the initial release through version 18.5, suggesting the vulnerability was present throughout the plugin's lifetime until the 18.5 patch.

RemediationAI

Immediately upgrade the WooCommerce Support Ticket System plugin to version 18.5 or later, which contains the patch for this path traversal vulnerability. Users should access the WordPress plugin management interface, navigate to the installed plugins section, and update the Vanquish WooCommerce Support Ticket System plugin to the latest available version. For organizations unable to immediately patch, implement filesystem-level access controls to restrict the web server process permissions to only necessary directories, disable unnecessary file operations in the plugin configuration if options exist, and monitor access logs for suspicious path traversal attempts (patterns with '../' or '..\' sequences). Additionally, maintain regular WordPress plugin audits and enable automatic security updates where feasible.
