CVE-2025-9772 is a medium-severity vulnerability affecting RemoteClinic version 2.0 and earlier. The vulnerability exists in the /staff/edit.php file, specifically involving the manipulation of the 'image' argument, which leads to an unrestricted file upload flaw. This vulnerability allows an unauthenticated remote attacker to upload arbitrary files to the server without any restrictions or validation. The lack of authentication and user interaction requirements makes exploitation straightforward. Since the vulnerability affects an unsupported version of RemoteClinic, no official patches or updates are available from the vendor. The CVSS 4.0 base score is 6.9, reflecting network attack vector, low complexity, no privileges or user interaction needed, and low impacts on confidentiality, integrity, and availability. The exploit code is publicly available, increasing the risk of exploitation despite no known active exploitation in the wild at this time. Unrestricted file upload vulnerabilities can lead to remote code execution, server compromise, data theft, or defacement, depending on the uploaded payload and server configuration. Given that RemoteClinic is a healthcare-related application, exploitation could also result in exposure of sensitive patient data or disruption of healthcare services.

For European organizations, particularly healthcare providers using RemoteClinic 2.0 or earlier, this vulnerability poses significant risks. Exploitation could lead to unauthorized access to internal systems, enabling attackers to deploy web shells or malware, potentially compromising patient data confidentiality and integrity. Disruption of healthcare services through defacement or denial of service could also occur, impacting patient care and trust. The fact that the product is no longer supported means organizations cannot rely on vendor patches and must consider alternative remediation strategies. Additionally, healthcare organizations in Europe are subject to strict data protection regulations such as GDPR, which mandates stringent controls over personal data. A breach resulting from this vulnerability could lead to regulatory penalties, reputational damage, and financial losses. The public availability of exploit code increases the urgency for European entities to address this issue proactively.

Since no official patches are available for RemoteClinic 2.0 due to end-of-life status, European organizations should consider the following specific mitigations: 1) Immediately isolate any systems running RemoteClinic 2.0 from public internet access using network segmentation and firewall rules to limit exposure. 2) Implement strict web application firewalls (WAF) with custom rules to detect and block suspicious file upload attempts targeting the 'image' parameter in /staff/edit.php. 3) Conduct thorough manual code reviews or engage security experts to implement custom input validation and file type restrictions on the upload functionality if source code access is available. 4) Monitor logs for unusual file upload activity and scan uploaded files for malicious content. 5) Plan and execute migration to a supported, secure alternative application or a newer version of RemoteClinic if available. 6) Employ intrusion detection/prevention systems (IDS/IPS) tuned to detect exploitation attempts of this vulnerability. 7) Educate IT staff about this vulnerability and the risks of using unsupported software, emphasizing the need for timely upgrades and patching in the future.
