CVE-2022-24831 is a medium-severity SQL injection vulnerability affecting 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 arises from improper neutralization of special elements in SQL commands (CWE-89), specifically due to the use of unsafe string concatenation to build SQL queries instead of employing parameterized prepared statements. This flaw exists in OpenClinica versions prior to 3.13.1 and in incremental versions up to but not including 3.16.1, where the issue has been patched. Exploiting this vulnerability allows an attacker to inject malicious SQL code, potentially enabling unauthorized access to, modification of, or deletion of sensitive clinical data stored within the backend databases. Given the nature of clinical data, this could lead to significant breaches of confidentiality and data integrity. No known workarounds exist, making upgrading to the fixed versions critical. Although no exploits have been reported in the wild, the vulnerability's presence in a critical healthcare data management system elevates the risk profile, especially considering the sensitive nature of the data handled by OpenClinica. The vulnerability does not require authentication or user interaction to exploit if the attacker can reach the vulnerable interface, increasing the attack surface.

For European organizations, particularly those involved in clinical research, pharmaceutical development, and healthcare data management, this vulnerability poses a significant risk. Successful exploitation could lead to unauthorized disclosure of sensitive patient and trial data, undermining patient privacy and violating GDPR regulations, which could result in substantial legal and financial penalties. Data integrity could also be compromised, potentially affecting the validity of clinical trial results and regulatory submissions. Availability impacts could arise if attackers manipulate or delete data, disrupting ongoing clinical studies and delaying critical medical research. The reputational damage to organizations handling such sensitive data could be severe, eroding trust among patients, partners, and regulatory bodies. Given the increasing reliance on digital platforms for clinical data management in Europe, the vulnerability could have widespread implications if not promptly addressed.

Organizations using OpenClinica should immediately verify their software versions and upgrade to the patched releases (3.13.1, 3.14.1, 3.15.9, or 3.16.1) as appropriate. Beyond upgrading, it is essential to conduct thorough code reviews and security audits focusing on SQL query construction to ensure no other injection points exist. Implementing Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection attempts targeting OpenClinica endpoints can provide an additional protective layer during the upgrade process. Restricting database user privileges to the minimum necessary can limit the impact of a successful injection. Monitoring database logs and application logs for unusual query patterns or errors indicative of injection attempts should be established. Additionally, organizations should ensure that all backups of clinical data are current and securely stored to enable recovery in case of data tampering or loss. Training developers and administrators on secure coding practices, especially regarding input validation and use of prepared statements, will help prevent similar vulnerabilities in the future.
