CVE-2025-67968: Real Homes CRM File Upload Vulnerability

CVE-2025-67968 Overview

CVE-2025-67968 is an Unrestricted Upload of File with Dangerous Type vulnerability (CWE-434) affecting the InspiryThemes Real Homes CRM WordPress plugin. This vulnerability allows attackers to upload malicious files to vulnerable WordPress installations, potentially leading to remote code execution and complete site compromise.

The vulnerability exists due to insufficient file type validation in the file upload functionality of the Real Homes CRM plugin. Attackers can exploit this weakness to upload files with dangerous extensions, such as PHP web shells, which can then be executed on the server to gain unauthorized access.

Critical Impact

Attackers can upload and execute malicious files on vulnerable WordPress sites, potentially leading to complete server compromise, data theft, and lateral movement within the hosting environment.

Affected Products

• InspiryThemes Real Homes CRM plugin version 1.0.0 and earlier
• WordPress installations running the vulnerable realhomes-crm plugin

Technical Details for CVE-2025-67968

Vulnerability Analysis

This vulnerability falls under CWE-434 (Unrestricted Upload of File with Dangerous Type), a common and dangerous web application flaw. The Real Homes CRM plugin fails to properly validate and restrict file types during the upload process. When file upload functionality does not enforce strict allowlists for permitted file extensions and MIME types, attackers can bypass intended restrictions and upload executable content.

In WordPress environments, successful exploitation of arbitrary file upload vulnerabilities is particularly severe because uploaded PHP files can be directly executed by the web server, providing attackers with immediate code execution capabilities within the context of the web application.

Root Cause

The root cause of this vulnerability is improper input validation in the file upload handling code within the Real Homes CRM plugin. The plugin does not adequately:

• Validate file extensions against a strict allowlist of permitted types
• Verify MIME types server-side to prevent content-type spoofing
• Sanitize or rename uploaded files to prevent execution
• Store uploaded files outside the web-accessible directory structure

This lack of defense-in-depth allows malicious actors to circumvent any client-side restrictions and upload dangerous file types directly to the server.

Attack Vector

Exploitation of this vulnerability typically follows this pattern:

1. An attacker identifies a WordPress site running the vulnerable Real Homes CRM plugin (version 1.0.0 or earlier)
2. The attacker locates the file upload endpoint exposed by the plugin
3. A malicious file (commonly a PHP web shell) is crafted and uploaded, potentially with a double extension or manipulated content-type header to bypass weak validation
4. Once uploaded, the attacker accesses the malicious file directly via the web server
5. The PHP code executes, granting the attacker remote code execution on the server

The attack can be executed remotely without authentication in some configurations, making it particularly dangerous for publicly accessible WordPress installations.

Detection Methods for CVE-2025-67968

Indicators of Compromise

• Unexpected PHP files appearing in WordPress upload directories (typically wp-content/uploads/)
• Web server access logs showing requests to unusual file paths within plugin directories
• New or modified files with suspicious names or double extensions (e.g., image.php.jpg, shell.php)
• Unexpected outbound network connections from the web server
• Web application firewall logs showing blocked file upload attempts with malicious payloads

Detection Strategies

• Implement file integrity monitoring on WordPress installations to detect unauthorized file additions
• Configure web application firewalls (WAF) to inspect and block malicious file upload attempts
• Monitor access logs for requests to newly created files in upload directories
• Deploy endpoint detection and response (EDR) solutions to identify web shell execution patterns
• Use WordPress security plugins that scan for known malicious file signatures

Monitoring Recommendations

• Enable verbose logging for file upload operations and review regularly
• Set up alerts for new PHP files created in non-standard directories
• Monitor process execution chains originating from the web server process
• Implement network monitoring to detect command-and-control communications from compromised servers

How to Mitigate CVE-2025-67968

Immediate Actions Required

• Immediately update the Real Homes CRM plugin if a patched version is available from InspiryThemes
• If no patch is available, consider temporarily disabling or removing the realhomes-crm plugin until a fix is released
• Audit WordPress upload directories for any suspicious or unexpected files
• Review web server access logs for evidence of exploitation attempts
• Implement additional file upload restrictions at the web server level

Patch Information

Users should monitor the official InspiryThemes channels and the WordPress plugin repository for security updates addressing this vulnerability. The Patchstack Vulnerability Report may contain additional remediation guidance as it becomes available.

Workarounds

• Restrict file upload functionality at the web server level using .htaccess rules or server configuration
• Implement a Web Application Firewall (WAF) rule to block file uploads containing PHP code
• Configure the uploads directory to disallow PHP execution
• Limit access to the WordPress admin area and plugin functionality to trusted IP addresses
• Consider using a WordPress security plugin that provides file upload filtering

# Apache .htaccess configuration to prevent PHP execution in uploads directory
# Place this file in wp-content/uploads/

<FilesMatch "\.(?i:php|php3|php4|php5|phtml|phps)$">
    Order Deny,Allow
    Deny from all
</FilesMatch>

# Alternatively, disable all script execution
<Files *>
    SetHandler none
    SetHandler default-handler
</Files>
