CVE-2025-7939 is a vulnerability identified in version 1.0 of the JPACookieShop 蛋糕商城JPA版, an e-commerce platform developed by jerryshensjf. The vulnerability resides in the addGoods function within the GoodsController.java file. This flaw allows an attacker to perform an unrestricted file upload remotely without requiring user interaction or authentication. Unrestricted file upload vulnerabilities typically enable attackers to upload malicious files, such as web shells or scripts, which can then be executed on the server. This can lead to full system compromise, data theft, or service disruption. The CVSS 4.0 base score is 5.3, indicating a medium severity level, with attack vector being network-based, low attack complexity, no privileges or user interaction required, and limited impact on confidentiality, integrity, and availability. However, the vulnerability's unrestricted upload nature means that if exploited, the attacker could escalate impact beyond the initial scope, depending on the server configuration and uploaded payload. No known exploits are currently reported in the wild, and no patches or mitigations have been officially published yet. The vulnerability affects only version 1.0 of the product, which suggests that newer versions may have addressed this issue or that the product is relatively new or niche. The lack of CWE classification limits detailed understanding of the exact coding flaw, but unrestricted upload vulnerabilities often stem from insufficient validation of file types, sizes, or paths in upload handlers.

For European organizations using JPACookieShop 蛋糕商城JPA版 1.0, this vulnerability poses a significant risk. Exploitation could allow attackers to upload malicious files leading to remote code execution, data breaches, or service outages. Given the e-commerce nature of the platform, sensitive customer data such as payment information, personal details, and transaction records could be exposed or manipulated. This could result in financial losses, reputational damage, and regulatory penalties under GDPR for failing to protect personal data. Additionally, compromised servers could be used as pivot points for further attacks within the organization's network. The medium CVSS score may underestimate the real-world impact if the attacker successfully uploads and executes malicious payloads. Since the attack requires no authentication or user interaction, it can be automated and scaled, increasing the threat level. Organizations relying on this software should consider the risk of supply chain attacks or third-party software vulnerabilities impacting their security posture.

Organizations should immediately audit their use of JPACookieShop 蛋糕商城JPA版 and identify any deployments of version 1.0. Until an official patch is released, practical mitigations include: 1) Implementing strict web application firewall (WAF) rules to detect and block suspicious file upload attempts, especially those targeting the addGoods endpoint. 2) Restricting file upload types and enforcing server-side validation to allow only expected file formats and sizes. 3) Applying network segmentation to isolate the e-commerce platform from critical internal systems to limit lateral movement if compromised. 4) Monitoring logs for unusual upload activity or execution of unexpected files. 5) Employing runtime application self-protection (RASP) tools to detect and prevent exploitation attempts in real time. 6) Considering temporary disabling or restricting the addGoods functionality if feasible. 7) Engaging with the vendor or community to obtain patches or updates and applying them promptly once available. 8) Conducting penetration testing focused on file upload mechanisms to identify similar weaknesses.
