CVE-2025-58963 is a critical security vulnerability identified in the 7oroof Medcity application, a healthcare management platform. The vulnerability arises from an unrestricted file upload mechanism that does not properly validate or restrict the types of files users can upload. This flaw allows an attacker to upload malicious files, specifically web shells, which are scripts that provide remote command execution capabilities on the server hosting the application. Once a web shell is uploaded, an attacker can execute arbitrary commands, potentially gaining full control over the web server and underlying infrastructure. The vulnerability affects all versions of Medcity prior to 1.1.9, with no authentication or user interaction required, making it trivially exploitable by remote attackers. The absence of a CVSS score indicates that the vulnerability is newly published and not yet fully assessed, but the technical details and nature of the flaw strongly suggest a high-risk profile. No patches or mitigations are currently linked, indicating that organizations must be vigilant and implement interim controls. The healthcare sector is particularly vulnerable due to the sensitive nature of patient data and the criticality of uninterrupted service. Attackers exploiting this vulnerability could exfiltrate sensitive data, disrupt healthcare services, or use the compromised server as a foothold for further network intrusion. The lack of known exploits in the wild provides a window for proactive defense but also underscores the urgency of addressing the issue before exploitation occurs.

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, resulting in heavy fines and reputational damage. The ability to upload web shells enables attackers to execute arbitrary code, potentially leading to full system compromise, data destruction, or ransomware deployment. Service availability could be severely impacted, disrupting critical healthcare operations and patient care. The breach of confidentiality and integrity of medical records could undermine trust in healthcare providers and cause long-term harm. Additionally, compromised servers could be leveraged as pivot points for broader attacks within healthcare networks or supply chains. The lack of authentication requirements for exploitation increases the attack surface, making even external attackers without credentials a threat. European healthcare entities must consider this vulnerability a top priority due to the critical nature of their services and the stringent regulatory environment.

Organizations should immediately inventory their use of 7oroof Medcity and identify affected versions. Until an official patch is released, implement strict file upload validation controls, including whitelisting allowed file types and scanning uploads for malicious content. Deploy web application firewalls (WAFs) with rules to detect and block web shell signatures and suspicious upload patterns. Restrict permissions on upload directories to prevent execution of uploaded files. Monitor server logs and network traffic for unusual activities indicative of web shell usage or remote code execution attempts. Conduct regular security audits and penetration testing focused on file upload functionalities. Educate staff on the risks of this vulnerability and establish incident response plans tailored to potential exploitation scenarios. Once patches become available, apply them promptly and verify their effectiveness. Consider network segmentation to isolate critical healthcare systems and limit lateral movement in case of compromise. Engage with 7oroof support and security communities for updates and shared intelligence.
