CVE-2025-13714 is a vulnerability identified in Tencent MedicalNet, specifically within the generate_model function, which improperly handles deserialization of untrusted data. Deserialization vulnerabilities occur when software deserializes data from untrusted sources without sufficient validation, allowing attackers to craft malicious serialized objects that, when deserialized, execute arbitrary code. In this case, the flaw allows remote attackers to execute code with root privileges, which is the highest level of system access, by tricking a user into interacting with malicious content such as a specially crafted webpage or file. The vulnerability is classified under CWE-502 (Deserialization of Untrusted Data) and has a CVSS v3.0 score of 7.8, indicating high severity. The attack vector is local (AV:L), requiring user interaction (UI:R), no privileges required (PR:N), and impacts confidentiality, integrity, and availability (all high). The vulnerability was reserved in late November 2025 and published in December 2025, with no known exploits in the wild at the time of reporting. Tencent MedicalNet is a healthcare-related product, and exploitation could lead to full system compromise, data theft, manipulation, or service disruption. The lack of proper input validation in the generate_model function is the root cause, making it critical to address deserialization safely. No patches were listed at the time, emphasizing the need for immediate attention from users and administrators.

For European organizations, particularly those in the healthcare sector using Tencent MedicalNet, this vulnerability poses a significant risk. Exploitation could lead to unauthorized access to sensitive patient data, manipulation of medical records, disruption of healthcare services, and potential ransomware deployment due to root-level code execution. The confidentiality of personal health information (PHI) is at high risk, which could lead to regulatory penalties under GDPR. Integrity and availability of medical systems could be compromised, affecting patient care and safety. The requirement for user interaction means phishing or social engineering campaigns could be used to trigger exploitation, increasing the attack surface. Given the critical nature of healthcare infrastructure, any compromise could have cascading effects on public health and trust. Additionally, the root-level access gained by attackers could allow lateral movement within networks, threatening broader organizational assets beyond MedicalNet itself.

European organizations should implement multiple layers of defense to mitigate this vulnerability. First, restrict user interactions with untrusted content by enforcing strict email and web filtering policies to reduce the risk of phishing or malicious file delivery. Second, apply strict input validation and sanitization on all data processed by Tencent MedicalNet, especially focusing on deserialization routines. Third, disable or replace unsafe deserialization mechanisms in the generate_model function if possible, or employ safe deserialization libraries that enforce type constraints and integrity checks. Fourth, monitor system and application logs for unusual deserialization activity or unexpected code execution patterns. Fifth, implement application whitelisting and endpoint protection solutions that can detect and block unauthorized code execution. Sixth, maintain a robust patch management process and apply security updates from Tencent as soon as they become available. Finally, conduct user awareness training to educate staff about the risks of interacting with suspicious files or links.
