CVE-2012-10064 in Omni Secure Files Plugin
Summary
by MITRE • 01/16/2026
Omni Secure Files plugin versions prior to 0.1.14 contain an arbitrary file upload vulnerability in the bundled plupload example endpoint. The /wp-content/plugins/omni-secure-files/plupload/examples/upload.php handler allows unauthenticated uploads without enforcing safe file type restrictions, enabling an attacker to place attacker-controlled files under the plugin's uploads directory. This can lead to remote code execution if a server-executable file type is uploaded and subsequently accessed.

The vulnerability identified as CVE-2012-10064 affects the Omni Secure Files WordPress plugin, specifically targeting versions prior to 0.1.14. This security flaw represents a critical arbitrary file upload vulnerability that exploits the plugin's bundled plupload example endpoint. The vulnerability exists within the upload.php handler located at /wp-content/plugins/omni-secure-files/plupload/examples/upload.php, which fails to implement proper file type validation mechanisms. The flaw allows unauthenticated attackers to bypass security restrictions and upload malicious files directly to the plugin's uploads directory without any authorization checks.
The technical implementation of this vulnerability stems from inadequate input validation and access control measures within the upload endpoint. The plupload example handler does not enforce safe file type restrictions, which creates an opportunity for attackers to upload files with potentially dangerous extensions such as .php, .asp, or .jsp. This weakness aligns with CWE-434, which describes insecure file upload vulnerabilities where applications fail to validate file types or enforce proper security controls during the upload process. The vulnerability operates at the application layer and can be exploited through standard web application attack vectors, making it particularly dangerous in web hosting environments.
The operational impact of this vulnerability extends beyond simple unauthorized file placement, as it creates a potential pathway for remote code execution. When executable file types are successfully uploaded to the server, attackers can leverage these files to execute arbitrary commands on the target system. This capability enables attackers to gain persistent access to the compromised WordPress installation, potentially leading to full system compromise. The vulnerability affects the entire WordPress ecosystem where the plugin is installed, as the upload handler is accessible without authentication, making it particularly attractive to automated exploitation tools. This scenario can be mapped to ATT&CK technique T1190, which covers exploiting vulnerabilities in web applications to achieve remote code execution.
The implications of this vulnerability are severe for WordPress administrators and security practitioners, as it demonstrates the critical importance of proper file upload validation in web applications. The vulnerability allows attackers to establish a foothold in the system that can be used for further exploitation, including data theft, privilege escalation, or establishing backdoors. Organizations using vulnerable versions of the Omni Secure Files plugin face significant risk of compromise, particularly if the uploaded files are subsequently accessed through the web server. Mitigation strategies should include immediate plugin updates to version 0.1.14 or later, implementation of additional file type restrictions, and regular security audits of plugin installations to identify similar vulnerabilities in other components. The vulnerability also highlights the necessity of following secure coding practices and implementing proper input validation at all levels of application development to prevent such critical flaws from occurring in the first place.
