CVE-2024-37513: Themewinter WPCafe Path Traversal Flaw

CVE-2024-37513 Overview

CVE-2024-37513 is a path traversal vulnerability in the Themewinter WPCafe plugin for WordPress. The flaw affects all versions up to and including 2.2.27. Authenticated attackers with low privileges can traverse directories outside the intended path and read arbitrary files on the server. Patchstack classifies the issue as a Local File Inclusion vulnerability, which increases the risk of remote code execution when combined with other primitives.

Critical Impact
An authenticated attacker can read sensitive server files such as wp-config.php, exposing database credentials, authentication keys, and other secrets that enable full site takeover.

Affected Products

Themewinter WPCafe WordPress plugin, versions up to and including 2.2.27
WordPress installations running the vulnerable WPCafe restaurant plugin
Sites relying on WPCafe for menu, reservation, and food ordering functionality

Technical Details for CVE-2024-37513

Vulnerability Analysis

The vulnerability is a path traversal issue tracked under CWE-22. WPCafe fails to properly sanitize user-supplied input that is used to construct file paths. An attacker sends crafted input containing directory traversal sequences such as ../ to escape the plugin's expected directory. The server then resolves the path to arbitrary files outside the intended scope. Patchstack categorizes this specifically as a Local File Inclusion vulnerability, meaning the traversed path is subsequently included or read by the plugin.

Root Cause

The root cause is missing or insufficient validation of pathname input before it reaches a file inclusion or file read operation. The plugin trusts a parameter that should be constrained to a whitelist of expected filenames. Because the check is absent, traversal sequences are passed through to the underlying filesystem call.

Attack Vector

Exploitation requires network access to the WordPress site and low-privilege authentication. An attacker with a subscriber or contributor account submits a request to a vulnerable WPCafe endpoint. The request contains a manipulated path parameter that references files outside the plugin directory. Successful exploitation returns file contents or executes included PHP files, resulting in disclosure of sensitive configuration data and potential code execution.

No public proof-of-concept is currently listed in NVD. The Patchstack advisory referenced in the CVE record provides additional technical context. See the Patchstack Local File Inclusion Vulnerability entry for details.

Detection Methods for CVE-2024-37513

Indicators of Compromise

HTTP requests to WPCafe plugin endpoints containing ../, ..%2f, or URL-encoded traversal sequences in query or POST parameters
Web server access logs showing reads of sensitive files such as wp-config.php, /etc/passwd, or .htaccess originating from the plugin
Unexpected PHP file inclusions traced to WPCafe request handlers in application logs
Authenticated sessions from low-privilege accounts issuing requests to administrative or file-handling endpoints

Detection Strategies

Deploy a web application firewall (WAF) rule to inspect requests targeting /wp-content/plugins/wp-cafe/ paths for traversal patterns
Correlate authenticated WordPress activity with abnormal file access patterns on the underlying host
Alert on any read access to wp-config.php outside legitimate administrative workflows
Review WordPress user activity logs for low-privilege accounts issuing requests to plugin AJAX or REST endpoints

Monitoring Recommendations

Enable verbose access logging on the web server and forward logs to a centralized SIEM for retention and analysis
Monitor file integrity for the WordPress installation directory and flag unexpected reads of configuration files
Track outbound network connections from the web host that could indicate post-exploitation activity
Baseline normal plugin request patterns and alert on deviations involving path parameters

How to Mitigate CVE-2024-37513

Immediate Actions Required

Update the Themewinter WPCafe plugin to a version later than 2.2.27 as soon as the vendor publishes a fixed release
Audit all WordPress user accounts and remove or downgrade any unnecessary low-privilege accounts that could be abused for authenticated exploitation
Rotate WordPress secrets in wp-config.php, including AUTH_KEY, SECURE_AUTH_KEY, and database credentials, if compromise is suspected
Review web server logs since July 2024 for traversal patterns targeting the WPCafe plugin

Patch Information

The CVE record states the vulnerability affects WPCafe from an unspecified initial version through 2.2.27. Administrators should consult the vendor's changelog and the Patchstack advisory to confirm the fixed release version and apply it through the standard WordPress plugin update mechanism.

Workarounds

Deactivate and remove the WPCafe plugin until a patched version is installed if the plugin is not business critical
Deploy WAF rules that block requests containing traversal sequences such as ../ and ..%2f targeting plugin endpoints
Restrict file system permissions so the web server user cannot read sensitive files outside the WordPress document root
Enforce the principle of least privilege for WordPress accounts and require multi-factor authentication for all authenticated users

bash
