CVE-2025-49885 is a critical vulnerability classified under CWE-434, which pertains to the unrestricted upload of files with dangerous types. This vulnerability affects the HaruTheme Drag and Drop Multiple File Upload (Pro) plugin for WooCommerce, specifically versions up to 5.0.6. The flaw allows an unauthenticated attacker to upload arbitrary files, including web shells, directly to the web server hosting the WooCommerce site. Because the plugin does not properly restrict or validate the types of files that can be uploaded, malicious actors can exploit this to execute remote code on the server, leading to full system compromise. The CVSS v3.1 score of 10.0 reflects the highest severity, indicating that the vulnerability is remotely exploitable over the network without any authentication or user interaction, and results in complete loss of confidentiality, integrity, and availability. The scope is changed (S:C), meaning the vulnerability affects resources beyond the vulnerable component itself, potentially impacting the entire web server and connected systems. Although no public exploits are currently known in the wild, the nature of the vulnerability and its critical severity make it a prime target for attackers once exploit code becomes available. The lack of available patches at the time of publication further increases the risk for affected installations. This vulnerability is particularly dangerous in e-commerce environments where sensitive customer data and payment information are processed, as attackers could leverage the web shell to steal data, deface websites, or use the compromised server as a pivot point for further attacks.

For European organizations using WooCommerce with the HaruTheme Drag and Drop Multiple File Upload (Pro) plugin, this vulnerability poses a severe risk. Exploitation could lead to unauthorized access to customer data, including personal and payment information, violating GDPR and other data protection regulations. The compromise of e-commerce platforms could result in financial losses, reputational damage, and legal penalties. Additionally, attackers could use the compromised servers to launch further attacks within the organization's network or against third parties, amplifying the impact. Given the critical nature of the vulnerability, organizations face potential service outages, data breaches, and long-term operational disruptions. The threat is especially acute for small and medium-sized enterprises (SMEs) that may lack robust security monitoring and incident response capabilities. The absence of authentication and user interaction requirements means that attackers can automate exploitation attempts, increasing the likelihood of widespread attacks across European WooCommerce sites using this plugin.

1. Immediate action should be to disable or remove the HaruTheme Drag and Drop Multiple File Upload (Pro) plugin until a security patch is released. 2. Monitor official HaruTheme and WooCommerce channels for updates or patches addressing CVE-2025-49885 and apply them promptly. 3. Implement strict web application firewall (WAF) rules to detect and block attempts to upload executable files or web shells, focusing on file extensions and MIME types commonly used in attacks. 4. Restrict file upload permissions on the server to prevent execution of uploaded files, for example by configuring the web server to disallow execution in upload directories. 5. Conduct thorough security audits and scanning of WooCommerce installations to identify any signs of compromise or unauthorized file uploads. 6. Employ network segmentation to isolate e-commerce systems from other critical infrastructure, limiting lateral movement if a compromise occurs. 7. Enhance logging and monitoring to detect anomalous file upload activities and unusual server behavior. 8. Educate site administrators about the risks of installing unverified plugins and the importance of timely updates. 9. Consider alternative, more secure file upload solutions that enforce strict validation and sanitization of uploaded content.
