CVE-2025-9775 is a medium-severity vulnerability affecting RemoteClinic version 2.0, specifically in the /staff/edit-my-profile.php file. The vulnerability arises from an unrestricted file upload flaw related to the 'image' argument. This flaw allows an unauthenticated remote attacker to upload arbitrary files without any restrictions or validation. The vulnerability does not require any privileges or user interaction, making it remotely exploitable over the network. The CVSS 4.0 base score is 6.9, reflecting the network attack vector, low complexity, no authentication, and no user interaction required. The impact on confidentiality, integrity, and availability is rated as low individually but combined can lead to significant security risks. An attacker could upload malicious files such as web shells or scripts, potentially leading to remote code execution, data compromise, or service disruption. Although no known exploits are currently observed in the wild, the exploit code has been publicly disclosed, increasing the risk of exploitation. The vulnerability is limited to RemoteClinic 2.0, a healthcare-related software product, which likely manages sensitive patient and staff data. The lack of patch information suggests that a fix may not yet be available, emphasizing the need for immediate mitigation efforts.

For European organizations, especially healthcare providers using RemoteClinic 2.0, this vulnerability poses a significant risk. Exploitation could lead to unauthorized access to sensitive patient data, violating GDPR and other data protection regulations, resulting in legal and financial penalties. The ability to upload arbitrary files could allow attackers to deploy web shells or malware, leading to full system compromise, data theft, or ransomware deployment. This could disrupt healthcare services, impacting patient care and trust. The medium severity rating reflects that while the vulnerability is serious, exploitation requires the presence of the vulnerable software and network exposure. However, given the critical nature of healthcare data and services, even medium-severity vulnerabilities can have outsized consequences in this sector. Organizations may face reputational damage and operational downtime if exploited.

1. Immediate mitigation should include restricting access to the /staff/edit-my-profile.php endpoint via network controls such as firewalls or VPNs to limit exposure to trusted users only. 2. Implement strict input validation and file type restrictions on the 'image' upload parameter to prevent unauthorized file types from being uploaded. 3. Monitor web server logs for suspicious upload activity or unexpected file types. 4. Employ web application firewalls (WAFs) with rules to detect and block malicious file uploads targeting this endpoint. 5. If possible, disable the image upload feature temporarily until a patch is available. 6. Conduct a thorough audit of uploaded files and system integrity to detect any prior exploitation. 7. Engage with the vendor for timely patching and updates. 8. Educate staff about the risks and signs of compromise related to this vulnerability. 9. Implement network segmentation to isolate critical healthcare systems from internet-facing components. 10. Regularly back up critical data and verify restore procedures to minimize impact from potential attacks.
