CVE-2024-50652 identifies a file upload vulnerability in the java_shop 1.0 e-commerce platform, specifically within the avatar upload functionality. The vulnerability allows an attacker to bypass restrictions and upload arbitrary files, which can include malicious scripts or executables. This is due to insufficient validation or sanitization of uploaded files, categorized under CWE-434. The attack vector is network-based (AV:N), requires no privileges (PR:N), but does require user interaction (UI:R), such as convincing a user to upload a crafted file or triggering the upload process. The vulnerability affects confidentiality, integrity, and availability by enabling unauthorized file uploads that could lead to remote code execution, data leakage, or service disruption. Although no patches or known exploits are currently available, the vulnerability is publicly disclosed and assigned a CVSS 3.1 score of 6.3, indicating a medium risk. The lack of authentication requirements and the potential for remote exploitation make this a notable threat for organizations using java_shop 1.0, especially those that allow user-generated content or avatar uploads. The absence of patch links suggests that mitigation currently relies on configuration changes and monitoring.

The impact of CVE-2024-50652 on organizations worldwide can be significant if exploited. Attackers could upload malicious files leading to remote code execution, enabling full system compromise or lateral movement within networks. This could result in data breaches, defacement, or denial of service, affecting business continuity and customer trust. The vulnerability compromises confidentiality by exposing sensitive data, integrity by allowing unauthorized modifications, and availability by potentially disrupting services. E-commerce platforms like java_shop are critical for online retail operations; thus, exploitation could lead to financial losses and reputational damage. The medium CVSS score reflects a moderate but actionable risk, especially since no authentication is required and exploitation only needs user interaction. Organizations with high volumes of user uploads or insufficient input validation are particularly vulnerable. The lack of known exploits in the wild currently reduces immediate risk but also means attackers may develop exploits soon after disclosure.

To mitigate CVE-2024-50652, organizations should immediately implement strict server-side validation of uploaded files, including checking file types, sizes, and content signatures to prevent dangerous files from being accepted. Employ allowlists for acceptable file extensions and reject all others. Disable or restrict the avatar upload functionality if not essential. Use sandboxing or isolated environments for handling uploads to minimize potential damage. Monitor logs for unusual upload activity and implement web application firewalls (WAFs) with rules targeting file upload anomalies. Keep abreast of java_shop vendor announcements for patches or security updates and apply them promptly once available. Educate users about the risks of uploading untrusted files and enforce multi-factor authentication to reduce the risk of account compromise that could facilitate exploitation. Conduct regular security assessments and penetration testing focused on file upload features. Consider deploying runtime application self-protection (RASP) solutions to detect and block malicious behaviors in real time.
