CVE-2025-11320 is a security vulnerability identified in the zhuimengshaonian wisdom-education software, specifically affecting versions 1.0.0 through 1.0.4. The flaw resides in the uploadFile function within the UploadController.java source file, where insufficient validation of the File argument allows attackers to perform unrestricted file uploads. This vulnerability can be exploited remotely without requiring user interaction or elevated privileges, making it accessible to unauthenticated attackers. The unrestricted upload capability could enable adversaries to upload malicious files such as web shells, scripts, or executables, potentially leading to unauthorized code execution, data leakage, or service disruption. The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:P) reflects network attack vector, low attack complexity, no user interaction, and partial impacts on confidentiality, integrity, and availability. Although no known exploits have been observed in the wild, the public disclosure of the vulnerability increases the risk of exploitation attempts. The vulnerability affects the education sector software, which may be integrated into learning management systems or digital education platforms, thus posing risks to educational institutions relying on this product. The lack of available patches at the time of disclosure necessitates immediate mitigation efforts to reduce exposure.

For European organizations, particularly educational institutions and edtech providers using the zhuimengshaonian wisdom-education platform, this vulnerability poses a risk of unauthorized file uploads that could lead to remote code execution, data breaches, or denial of service. The partial compromise of confidentiality, integrity, and availability could disrupt educational services, expose sensitive student or staff data, and damage institutional reputation. Given the remote and unauthenticated nature of the exploit, attackers could leverage this vulnerability to establish persistent footholds or pivot within networks. The impact is amplified in environments where the software is integrated with critical infrastructure or contains sensitive personal data protected under GDPR. Additionally, the education sector's increasing digitalization in Europe makes such vulnerabilities attractive targets for cybercriminals or state-sponsored actors aiming to disrupt educational operations or exfiltrate data.

European organizations should immediately assess their deployment of the zhuimengshaonian wisdom-education software and prioritize mitigation. Since no official patches are currently available, practical steps include: 1) Implementing strict server-side validation to restrict allowed file types and sizes, blocking executable or script files; 2) Applying access controls to the upload endpoint, such as IP whitelisting or authentication layers, to limit exposure; 3) Employing web application firewalls (WAFs) with custom rules to detect and block suspicious upload attempts; 4) Monitoring logs and network traffic for anomalous file upload activities; 5) Isolating the upload functionality in a sandboxed environment to minimize potential damage; 6) Planning for rapid patch deployment once vendor updates are released; 7) Conducting security awareness training for administrators on this specific threat vector; 8) Reviewing and hardening server configurations to prevent execution of uploaded files in upload directories.
