CVE-2025-4336 in Store Manager for WooCommerce Plugin
Summary
by MITRE • 05/24/2025
The eMagicOne Store Manager for WooCommerce plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the set_file() function in all versions up to, and including, 1.2.5. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected site's server which may make remote code execution possible. This is only exploitable by unauthenticated attackers in default configurations where the the default password is left as 1:1, or where the attacker gains access to the credentials.

The vulnerability identified as CVE-2025-4336 affects the eMagicOne Store Manager for WooCommerce plugin, a widely used WordPress extension that facilitates e-commerce operations. This plugin suffers from a critical security flaw in its file upload functionality that stems from inadequate input validation mechanisms. The vulnerability specifically resides within the set_file() function where the plugin fails to properly validate file types during the upload process, creating a pathway for malicious actors to bypass security controls that are typically in place to prevent unauthorized file operations.
The technical flaw represents a classic case of insufficient validation and sanitization, which aligns with CWE-434, a weakness category that encompasses improper restriction of file uploads. When the set_file() function processes file uploads, it does not adequately verify the MIME type or file extension of uploaded content, allowing attackers to submit files with potentially dangerous extensions such as .php, .asp, or .jsp that could execute code on the target server. This vulnerability operates under the principle of insecure file handling, where the application accepts files without proper validation, creating a direct attack surface that can be exploited by threat actors.
The operational impact of this vulnerability is severe and multifaceted, particularly when considering the default configuration settings that leave the plugin accessible to unauthenticated users. In scenarios where the default password remains unchanged at the 1:1 ratio, attackers can gain unauthorized access to upload capabilities and subsequently deploy malicious payloads that may result in complete system compromise. The vulnerability enables remote code execution capabilities, which can be leveraged to establish persistent backdoors, exfiltrate sensitive data, or use the compromised server as a launching point for further attacks within the network. This makes the vulnerability particularly dangerous in environments where WordPress installations are not properly secured or regularly updated.
The exploitation of this vulnerability follows patterns consistent with ATT&CK technique T1190, which involves leveraging vulnerabilities in web applications to achieve code execution. Attackers can leverage the unauthenticated upload capability to place malicious files on the server, potentially using techniques such as uploading web shells or reverse shells that maintain persistent access. The attack vector is particularly concerning because it requires no prior authentication, making it accessible to anyone who can access the plugin's upload functionality. Organizations running vulnerable versions of this plugin face significant risk of data breaches, service disruption, and potential regulatory violations, especially in environments where WordPress is used for handling sensitive customer information or financial transactions.
Mitigation strategies should include immediate patching of the affected plugin to version 1.2.6 or later, which addresses the file validation issues in the set_file() function. Additionally, administrators should enforce strong password policies and disable default accounts immediately, as the vulnerability can be exploited through default credentials. Network segmentation and web application firewalls can provide additional layers of protection by monitoring and blocking suspicious file upload activities. Regular security audits and vulnerability assessments should be conducted to identify similar issues in other plugins or themes, and automated patch management systems should be implemented to ensure timely updates. The vulnerability also underscores the importance of principle of least privilege in web application security, where file upload capabilities should be restricted to authenticated users with appropriate permissions and should include robust validation mechanisms to prevent malicious file execution.
