CVE-2012-10064: Omni Secure Files Plugin RCE Vulnerability

CVE-2012-10064 Overview

CVE-2012-10064 is a critical arbitrary file upload vulnerability affecting the Omni Secure Files WordPress plugin versions prior to 0.1.14. The vulnerability exists in the bundled plupload example endpoint located at /wp-content/plugins/omni-secure-files/plupload/examples/upload.php. This handler allows unauthenticated uploads without enforcing safe file type restrictions, enabling attackers to place malicious files under the plugin's uploads directory. Successful exploitation can lead to remote code execution if a server-executable file type (such as PHP) is uploaded and subsequently accessed.

Critical Impact

Unauthenticated attackers can upload arbitrary files including malicious PHP scripts, potentially achieving full remote code execution on vulnerable WordPress installations.

Affected Products

• Omni Secure Files WordPress Plugin versions prior to 0.1.14
• WordPress installations with vulnerable Omni Secure Files plugin enabled

Technical Details for CVE-2012-10064

Vulnerability Analysis

This vulnerability falls under CWE-434 (Unrestricted Upload of File with Dangerous Type). The Omni Secure Files plugin bundled a plupload library that included example upload handlers intended for demonstration purposes. Unfortunately, these example files were deployed in production environments without proper security controls.

The vulnerable endpoint at upload.php accepts file uploads from any unauthenticated user without validating the file type, extension, or content. This allows attackers to upload server-side executable files such as PHP web shells. Once uploaded, these files can be accessed directly through the web server, triggering code execution with the privileges of the web server process.

The network-accessible attack vector requires no privileges or user interaction, making this vulnerability particularly dangerous for internet-facing WordPress sites. The impact encompasses complete compromise of confidentiality, integrity, and availability of the affected system.

Root Cause

The root cause is the inclusion of example/demonstration code from the plupload library in a production plugin without implementing proper file type validation or authentication controls. The upload.php script was designed as a developer example and lacks the security measures required for production use, including:

• No authentication or authorization checks
• No file extension whitelist enforcement
• No MIME type validation
• No content inspection for malicious payloads

Attack Vector

The attack vector is network-based with low complexity. An unauthenticated attacker can craft an HTTP POST request to the vulnerable endpoint at /wp-content/plugins/omni-secure-files/plupload/examples/upload.php. The request contains a malicious file, such as a PHP web shell, which is saved to the plugin's uploads directory without any validation.

The attacker then accesses the uploaded file directly via HTTP, causing the web server to execute the malicious code. This grants the attacker remote code execution capabilities on the target server, potentially leading to complete system compromise, data theft, or lateral movement within the network.

Detection Methods for CVE-2012-10064

Indicators of Compromise

• Unexpected files appearing in /wp-content/plugins/omni-secure-files/plupload/examples/ or related upload directories
• HTTP POST requests to /wp-content/plugins/omni-secure-files/plupload/examples/upload.php from external sources
• New PHP files with unusual names or obfuscated content in plugin directories
• Web server logs showing access to recently created files in the plupload directory

Detection Strategies

• Monitor web server access logs for POST requests targeting the vulnerable upload.php endpoint
• Implement file integrity monitoring on WordPress plugin directories to detect unauthorized file additions
• Deploy web application firewall (WAF) rules to block requests to known vulnerable plupload example endpoints
• Use WordPress security plugins to scan for outdated or vulnerable plugin versions

Monitoring Recommendations

• Configure alerting for any new file creation events within WordPress plugin directories
• Monitor outbound network connections from the web server process for potential reverse shell activity
• Implement regular vulnerability scanning of WordPress installations to identify outdated plugins
• Review web server error logs for suspicious PHP execution attempts in upload directories

How to Mitigate CVE-2012-10064

Immediate Actions Required

• Update Omni Secure Files plugin to version 0.1.14 or later immediately
• If unable to update, remove or disable the Omni Secure Files plugin entirely
• Delete the vulnerable upload.php file located at /wp-content/plugins/omni-secure-files/plupload/examples/upload.php
• Audit the plugin uploads directory for any suspicious or unexpected files and remove unauthorized content
• Review web server logs for evidence of exploitation attempts

Patch Information

The vulnerability is addressed in Omni Secure Files version 0.1.14 and later. Users should update to the latest available version through the WordPress plugin update mechanism or by downloading from the WordPress Plugin Directory.

Additional technical details are available from the VulnCheck Advisory and Wordfence Vulnerability Analysis.

Workarounds

• Remove or rename the vulnerable upload.php example file if plugin update is not immediately possible
• Block access to the /plupload/examples/ directory via web server configuration
• Implement web application firewall rules to deny POST requests to the vulnerable endpoint
• Restrict plugin directory permissions to prevent web-writable uploads where possible

# Block access to vulnerable plupload examples directory via Apache .htaccess
# Add to /wp-content/plugins/omni-secure-files/.htaccess
<Directory "plupload/examples">
    Require all denied
</Directory>

# Or for Nginx, add to server block:
# location ~* /wp-content/plugins/omni-secure-files/plupload/examples/ {
#     deny all;
# }
