CVE-2025-4336 is a high-severity vulnerability affecting the eMagicOne Store Manager for WooCommerce plugin for WordPress, specifically all versions up to and including 1.2.5. The vulnerability arises from improper validation of file types in the set_file() function, categorized under CWE-434 (Unrestricted Upload of File with Dangerous Type). This flaw allows unauthenticated attackers to upload arbitrary files to the affected server. The critical risk here is that such arbitrary file uploads can lead to remote code execution (RCE), enabling attackers to execute malicious code on the server hosting the WordPress site. However, exploitation requires either the default weak credentials (username:password as 1:1) to remain unchanged or the attacker to have obtained valid credentials. The CVSS v3.1 base score is 8.1, reflecting a high severity due to network attack vector, no privileges required, no user interaction, and high impact on confidentiality, integrity, and availability. No known exploits are currently reported in the wild, but the vulnerability's nature and ease of exploitation under default or compromised credentials make it a significant threat. The absence of patch links suggests that a fix may not yet be publicly available or is pending release, increasing the urgency for mitigation.

For European organizations using the eMagicOne Store Manager for WooCommerce plugin, this vulnerability poses a substantial risk. Successful exploitation could lead to full compromise of the affected web server, resulting in data breaches, defacement, or use of the server as a pivot point for further attacks within the corporate network. Confidential customer data, including payment and personal information, could be exposed or manipulated, severely damaging trust and potentially violating GDPR regulations. The availability of the eCommerce platform could be disrupted, impacting business operations and revenue. Given the plugin's integration with WooCommerce, a widely used eCommerce solution, the threat extends to numerous small and medium-sized enterprises across Europe that rely on WordPress-based online stores. The requirement for default credentials or credential compromise means organizations with weak password policies or insufficient credential management are at higher risk. The lack of known exploits in the wild currently provides a small window for proactive defense, but the high severity score and potential impact necessitate immediate attention.

1. Immediately audit all instances of the eMagicOne Store Manager for WooCommerce plugin to identify affected versions (up to 1.2.5). 2. Change any default credentials (username:password 1:1) to strong, unique passwords to prevent unauthorized access. 3. Implement strict credential management policies, including multi-factor authentication where possible, to reduce the risk of credential compromise. 4. Restrict file upload permissions and enforce server-side validation to block dangerous file types, even if the plugin does not do so natively. 5. Monitor web server logs for unusual file upload activities or access attempts to the plugin's upload endpoints. 6. Isolate the WordPress environment using containerization or sandboxing to limit the impact of potential RCE. 7. Regularly backup website and server data to enable recovery in case of compromise. 8. Stay alert for official patches or updates from emagicone and apply them promptly once available. 9. Consider deploying Web Application Firewalls (WAF) with custom rules to detect and block suspicious upload attempts targeting the vulnerable function. 10. Conduct security awareness training for administrators managing WordPress sites to recognize and remediate weak credential usage and suspicious activities.
