CVE-2025-15360 is a vulnerability identified in the newbee-mall-plus e-commerce platform version 2.0.0, specifically within the Upload function of the UploadController.java file. The vulnerability arises from insufficient validation of uploaded files, allowing an attacker with authenticated high-level privileges to upload arbitrary files without restriction. This unrestricted upload capability can be exploited remotely, potentially enabling attackers to upload malicious scripts or executables that could lead to further system compromise, data leakage, or service disruption. The vulnerability does not require user interaction but does require the attacker to have high-level privileges, which limits the attack surface to some extent. The CVSS 4.0 score of 5.1 reflects a medium severity, considering the network attack vector, low complexity, no user interaction, and partial impacts on confidentiality, integrity, and availability. The vendor was contacted but did not respond, and no patches or mitigations have been officially released. Although no known exploits are currently active in the wild, the public disclosure of the vulnerability increases the risk that threat actors may develop exploits. The vulnerability impacts the Product Information Edit Page component, which is critical for managing product data, making it a strategic target for attackers aiming to manipulate e-commerce operations or inject malicious content.

For European organizations using newbee-mall-plus 2.0.0, this vulnerability poses a significant risk to the integrity and availability of their e-commerce platforms. Attackers with high-level access could upload malicious files, potentially leading to unauthorized code execution, data breaches, or defacement of product information pages. This could result in financial losses, reputational damage, and regulatory non-compliance, especially under GDPR requirements for data protection. The ability to upload arbitrary files could also facilitate the deployment of ransomware or other malware, disrupting business operations. Since the vulnerability affects a core component of product management, it could impact supply chain integrity and customer trust. The lack of vendor response and patches increases the urgency for organizations to implement their own mitigations. The medium severity rating indicates that while the vulnerability is serious, exploitation requires existing high privileges, somewhat limiting the attack scope to insiders or compromised accounts.

European organizations should implement strict server-side validation of all uploaded files, including checking file types, sizes, and content signatures to prevent malicious uploads. Employing allowlists for permitted file extensions and rejecting all others is critical. Additionally, isolating the upload directory with minimal permissions and disabling execution rights can reduce the risk of uploaded files being executed. Implement multi-factor authentication and robust access controls to limit high-privilege account access, reducing the likelihood of exploitation. Regularly audit and monitor upload endpoints and logs for unusual activity or unauthorized uploads. Employ web application firewalls (WAFs) with custom rules to detect and block suspicious upload attempts. Since no official patch is available, consider applying virtual patching techniques or restricting access to the vulnerable component until a vendor fix is released. Conduct security awareness training for administrators to recognize and report suspicious behavior. Finally, maintain up-to-date backups to enable recovery in case of compromise.
