CVE-2022-24830 is a path traversal vulnerability identified in OpenClinica, an open-source software platform widely used for Electronic Data Capture (EDC) and Clinical Data Management (CDM) in clinical trials and research. The vulnerability affects versions prior to 3.16 and arises from improper limitation of pathname inputs to restricted directories (CWE-22). Specifically, multiple endpoints in OpenClinica fail to adequately sanitize user-supplied file path parameters, allowing an attacker to traverse directories outside the intended file system boundaries. This can lead to arbitrary file read and write operations on the server hosting the application. The consequences of such unauthorized file access include exposure of sensitive clinical data, modification or deletion of critical files, and potentially remote code execution if malicious files are written and subsequently executed. Although no known exploits have been reported in the wild, the vulnerability is significant due to the sensitive nature of data managed by OpenClinica and the potential for severe operational disruption. The issue has been addressed in OpenClinica version 3.16, and users are strongly advised to upgrade to this or later versions to mitigate the risk. No workarounds are currently available, emphasizing the importance of timely patching. The vulnerability does not require authentication or user interaction, increasing its risk profile as it could be exploited remotely by unauthenticated attackers targeting exposed OpenClinica instances.

For European organizations, especially those involved in clinical research, pharmaceuticals, and healthcare, this vulnerability poses a substantial risk. Compromise of OpenClinica systems could lead to unauthorized disclosure of sensitive patient data and clinical trial results, violating GDPR and other data protection regulations, which could result in significant legal and financial penalties. Integrity of clinical data is critical for regulatory submissions and patient safety; thus, unauthorized modification could undermine trial validity and lead to erroneous conclusions or regulatory rejection. Availability impacts could disrupt ongoing clinical trials, delaying research and increasing operational costs. Given the strategic importance of clinical research in Europe and the reliance on OpenClinica by many institutions, exploitation could also damage organizational reputation and trust. Additionally, the potential for remote code execution elevates the threat to full system compromise, which could be leveraged for broader network intrusion or ransomware deployment.

1. Immediate upgrade of all OpenClinica instances to version 3.16 or later, which contains the patch for this vulnerability. 2. Conduct a thorough audit of all OpenClinica deployments to identify any exposed endpoints accessible from untrusted networks and restrict access using network segmentation and firewalls. 3. Implement strict input validation and sanitization at the application layer for any custom integrations or extensions interacting with file system paths. 4. Employ Web Application Firewalls (WAFs) with rules designed to detect and block path traversal attempts targeting OpenClinica endpoints. 5. Monitor logs for unusual file access patterns or errors indicative of exploitation attempts. 6. Regularly back up clinical data and system configurations to enable rapid recovery in case of compromise. 7. Educate system administrators and developers on secure coding practices related to file handling and path validation to prevent similar vulnerabilities in custom code. 8. Coordinate with clinical trial sponsors and regulatory bodies to ensure compliance and incident response readiness in case of data breaches.
