CVE-2025-1282: Car Dealer Path Traversal Vulnerability

CVE-2025-1282 Overview

CVE-2025-1282 is a path traversal vulnerability in the Car Dealer Automotive WordPress Theme by ThemeMakers. The flaw exists in the delete_post_photo() and add_car() functions, which fail to properly validate file paths supplied by authenticated users. All theme versions up to and including 1.6.3 are affected.

Authenticated attackers with Subscriber-level access or higher can delete arbitrary files on the server. Deleting wp-config.php triggers WordPress reinstallation mode, allowing attackers to point the site at an attacker-controlled database and achieve remote code execution. The add_car() function additionally allows reading arbitrary files from the server.

Critical Impact
Subscriber-level attackers can delete wp-config.php to achieve site takeover and remote code execution on affected WordPress installations.

Affected Products

ThemeMakers Car Dealer Automotive WordPress Theme versions 1.6.3 and earlier
All WordPress sites running the Car Dealer Automotive Responsive theme
WordPress deployments allowing Subscriber-level registration on vulnerable theme versions

Technical Details for CVE-2025-1282

Vulnerability Analysis

The vulnerability falls under [CWE-22] Improper Limitation of a Pathname to a Restricted Directory (Path Traversal). Two AJAX-accessible functions in the theme, delete_post_photo() and add_car(), accept user-supplied file path parameters without sanitization or validation against an allowlisted directory.

An attacker authenticated as a low-privileged user supplies a relative path containing ../ sequences. The application resolves the path outside the intended uploads directory and operates on system-level files. The delete_post_photo() handler then invokes a file deletion routine on the resolved path.

Deleting wp-config.php removes the database credentials and forces WordPress into the installation workflow on the next request. An attacker visiting the site can then complete setup against a database they control, install a malicious plugin or theme, and execute arbitrary PHP. The add_car() function reads file contents into theme processing logic, enabling disclosure of source code, credentials, and secrets.

Root Cause

Both functions trust client-controlled file path input. The handlers lack capability checks restricting them to higher-privileged roles, lack nonce validation tied to authorized workflows, and lack canonical path checks confirming the target resides within the expected uploads subdirectory.

Attack Vector

Exploitation occurs over the network against the WordPress AJAX endpoint. The attacker requires Subscriber-level authentication, which is available by default on any WordPress site permitting open registration. The attacker submits a crafted POST request to the vulnerable AJAX action with a traversal payload in the file path parameter.

No verified public proof-of-concept code is available. See the Wordfence Vulnerability Report for additional technical details.

Detection Methods for CVE-2025-1282

Indicators of Compromise

Unexpected absence or modification timestamps on wp-config.php, .htaccess, or core WordPress PHP files
WordPress reverting to the installation screen (/wp-admin/install.php) without administrator action
AJAX POST requests to admin-ajax.php containing action=delete_post_photo or action=add_car with ../ sequences in parameters
New low-privileged user registrations immediately followed by AJAX requests targeting the theme handlers

Detection Strategies

Monitor web server access logs for POST requests to admin-ajax.php with traversal patterns such as ..%2F, ../, or absolute paths in parameters
Audit WordPress user registration logs for new Subscriber accounts created shortly before file system anomalies
File integrity monitoring on the WordPress document root with alerting on deletion of wp-config.php and theme/plugin PHP files

Monitoring Recommendations

Enable verbose logging on the WordPress AJAX endpoint and forward to a centralized SIEM for path traversal pattern matching
Track HTTP 500 errors and unexpected site reinstall prompts as signals of post-exploitation activity
Alert on filesystem-level deletion events for any file matching wp-config.php across monitored web hosts

How to Mitigate CVE-2025-1282

Immediate Actions Required

Disable or uninstall the Car Dealer Automotive theme if a patched version is not yet available
Disable open user registration in WordPress general settings until the theme is patched
Verify the integrity of wp-config.php and back up the file outside the web root
Audit existing Subscriber accounts and remove any unrecognized registrations

Patch Information

No fixed version is identified in the NVD record at the time of publication. Administrators should consult the vendor listing on ThemeForest and the Wordfence Vulnerability Report for updates beyond version 1.6.3.

Workarounds

Restrict access to wp-admin/admin-ajax.php using a Web Application Firewall rule that blocks path traversal sequences in request bodies
Set the WordPress general option users_can_register to 0 to prevent unauthenticated account creation
Apply filesystem permissions making wp-config.php immutable where supported (for example, chattr +i on Linux)

bash

# Configuration example: harden wp-config.php and disable registration
chmod 400 /var/www/html/wp-config.php
chown root:www-data /var/www/html/wp-config.php
wp option update users_can_register 0
