CVE-2025-14965 identifies a path traversal vulnerability in the yougou-mall e-commerce platform, specifically affecting the Upload function implemented in src/main/java/per/ccm/ygmall/extra/controller/ResourceController.java. The vulnerability arises from insufficient validation or sanitization of file path inputs during file upload operations, allowing an attacker to manipulate the file path parameter to traverse directories outside the intended upload directory. This can lead to unauthorized access or modification of files on the server, potentially exposing sensitive data or enabling further compromise. The product uses a rolling release model, which complicates version tracking and patch management, as no fixed version numbers or patches are currently available. The CVSS 4.0 score is 5.1 (medium severity), reflecting that the attack vector is adjacent network (AV:A), requires low complexity (AC:L), no authentication (PR:L), no user interaction (UI:N), and has limited impact on confidentiality, integrity, and availability (VC:L, VI:L, VA:L). No known exploits have been reported in the wild, but the vulnerability presents a risk especially if the server hosts sensitive data or critical services. The lack of authentication requirement and the potential to access arbitrary files make this a concern for organizations relying on yougou-mall for their e-commerce operations.

For European organizations, exploitation of this vulnerability could lead to unauthorized disclosure or modification of sensitive files on the server hosting yougou-mall, potentially including configuration files, user data, or application code. This could facilitate further attacks such as privilege escalation, data breaches, or service disruption. The impact is particularly significant for organizations handling personal data under GDPR, as unauthorized access could lead to compliance violations and reputational damage. The medium severity indicates that while the vulnerability is exploitable remotely with low complexity, the scope of impact is limited by the need for adjacent network access and the limited impact on confidentiality, integrity, and availability. However, given the critical role of e-commerce platforms in business operations, even limited disruptions or data leaks can have financial and operational consequences. Organizations using this platform should prioritize assessment and mitigation to prevent exploitation.

Given the rolling release nature of yougou-mall and the absence of official patches, European organizations should implement immediate compensating controls. These include: 1) Enforce strict input validation and sanitization on all file upload parameters to prevent path traversal sequences such as '../'. 2) Restrict file upload directories using server-side controls and ensure the application runs with the least privileges necessary to limit file system access. 3) Employ web application firewalls (WAF) with rules targeting path traversal attack patterns to detect and block malicious requests. 4) Monitor file system changes and access logs for unusual activity indicative of exploitation attempts. 5) Isolate the upload functionality in a sandboxed environment or container to limit potential damage. 6) Regularly audit and review the application code and deployment configurations for security best practices. 7) Engage with the vendor or community to track updates or patches addressing this vulnerability. 8) Consider network segmentation to limit adjacent network access to the application server. These measures will reduce the risk until an official patch or update is available.
