CVE-2025-58963 is a critical security vulnerability affecting the 7oroof Medcity application, specifically versions prior to 1.1.9. The vulnerability arises from an unrestricted file upload flaw that allows attackers to upload files with dangerous types, including web shells, directly to the web server hosting Medcity. This lack of proper validation or restriction on file types enables remote attackers to execute arbitrary code on the server without requiring any authentication or user interaction. The vulnerability impacts confidentiality, integrity, and availability by allowing attackers to gain full control over the affected system, potentially leading to data theft, manipulation, or denial of service. The CVSS v3.1 base score of 9.8 reflects the critical severity, with attack vector being network-based, low attack complexity, no privileges required, and no user interaction needed. Although no known exploits have been reported in the wild yet, the vulnerability's characteristics make it a prime target for exploitation. Medcity is a healthcare management platform, and compromise of such systems can have severe consequences including exposure of sensitive patient data and disruption of healthcare services. The vulnerability was reserved in early September 2025 and published in October 2025, indicating recent discovery and disclosure. No patches or fixes are currently linked, so organizations must rely on interim mitigations until official updates are released.

For European organizations, especially those in the healthcare sector using 7oroof Medcity, this vulnerability poses a significant risk. Exploitation can lead to unauthorized access to sensitive patient data, violating GDPR and other data protection regulations, potentially resulting in heavy fines and reputational damage. The ability to upload and execute web shells can allow attackers to move laterally within networks, deploy ransomware, or disrupt critical healthcare services, impacting patient care and safety. Given the critical nature of healthcare infrastructure in Europe and the increasing targeting of such sectors by cybercriminals and nation-state actors, the impact extends beyond data loss to operational disruption. The vulnerability's ease of exploitation and lack of required authentication increase the likelihood of attacks, making timely mitigation essential. Additionally, the potential for widespread compromise could affect supply chains and interconnected healthcare providers across multiple countries.

1. Immediately monitor for any suspicious file uploads or unexpected web shell files on Medcity servers. 2. Implement strict server-side validation to restrict allowed file types and reject any files that could be executed as code. 3. Configure web server permissions to prevent execution of uploaded files, especially in upload directories. 4. Employ web application firewalls (WAFs) with rules to detect and block malicious upload attempts. 5. Isolate Medcity servers in segmented network zones to limit lateral movement if compromised. 6. Regularly audit and review logs for anomalous activities related to file uploads. 7. Engage with 7oroof for timely patches or updates and apply them as soon as they become available. 8. Educate IT and security teams about this vulnerability and ensure incident response plans include scenarios involving web shell attacks. 9. Consider deploying endpoint detection and response (EDR) tools on servers to detect post-exploitation behaviors. 10. Backup critical data regularly and verify restoration procedures to mitigate ransomware or destructive attacks stemming from exploitation.
