The Car Dealer Automotive WordPress Theme, a responsive theme for WordPress, is vulnerable to arbitrary file deletion due to insufficient file path validation in the `delete_post_photo()` and `add_car()` functions in versions up to and including 1.6.3. This vulnerability allows authenticated attackers with Subscriber-level access or higher to delete arbitrary files on the server. By exploiting this flaw, attackers can delete critical files such as wp-config.php, leading to remote code execution (RCE). Additionally, the `add_car()` function may allow attackers to read arbitrary files, further escalating the risk.
The vulnerability arises because the theme does not properly sanitize user-supplied file paths before performing file operations. Attackers can manipulate file paths to target sensitive system files, compromising the integrity and availability of the WordPress installation. This issue is particularly severe because it can be exploited by low-privileged users, making it accessible to a wide range of attackers.
DailyCVE Form:
Platform: WordPress
Version: 1.6.3 and earlier
Vulnerability: Arbitrary File Deletion
Severity: Critical
Date: 02/27/2025
What Undercode Say:
Exploitation:
1. Exploit Code Example:
// Exploit for arbitrary file deletion $file_path = "../../../../wp-config.php"; delete_post_photo($file_path);
This code snippet demonstrates how an attacker could manipulate the file path to delete the `wp-config.php` file.
2. Steps to Exploit:
- Gain Subscriber-level access to the WordPress site.
- Use the `delete_post_photo()` function to delete critical files.
- Alternatively, use the `add_car()` function to read sensitive files.
Protection:
1. Patch Application:
- Update the Car Dealer Automotive WordPress Theme to the latest version (if available).
- Remove or disable the theme if no patch is available.
2. File Path Sanitization:
// Secure file path validation
function sanitize_file_path($file_path) {
$allowed_paths = [bash];
foreach ($allowed_paths as $path) {
if (strpos($file_path, $path) === 0) {
return $file_path;
}
}
return false;
}
This code ensures that only files within allowed directories can be accessed.
3. Access Control:
- Restrict file deletion and upload capabilities to trusted users only.
- Implement role-based access control (RBAC) to limit Subscriber-level permissions.
4. Monitoring:
- Use WordPress security plugins like Wordfence to monitor and block suspicious activities.
- Regularly audit server logs for unauthorized file operations.
5. Backup:
- Maintain regular backups of the WordPress installation and database to recover from potential attacks.
Commands:
- Check Theme Version:
wp theme list --field=name,version
- Disable Vulnerable Theme:
wp theme disable car-dealer-automotive
- Scan for Vulnerabilities:
wp vuln status --theme
By following these steps, administrators can mitigate the risks associated with CVE-2025-1282 and protect their WordPress installations from exploitation.
