CVE-2024-45527 is a vulnerability identified in REDCap version 14.7.0, a widely used research data capture platform. The flaw arises from insufficient input sanitization in the project title field during the 'New Project' creation process, allowing an attacker to inject arbitrary HTML code. This HTML injection can be leveraged to execute a logout Cross-Site Request Forgery (CSRF) attack by redirecting users to index.php?logout=1, forcibly logging them out of their session. Beyond logout CSRF, the injected HTML can include links to external phishing websites, enabling attackers to conduct social engineering attacks by tricking users into visiting malicious sites. The vulnerability does not require any authentication or elevated privileges to exploit, but it does require the victim to interact with the crafted project title content, such as viewing or interacting with the affected page. The CVSS 3.1 score of 6.1 reflects a medium severity, with network attack vector, low attack complexity, no privileges required, user interaction needed, and a scope change due to session manipulation. The vulnerability is categorized under CWE-352 (Cross-Site Request Forgery). No patches or exploits are currently publicly available, but the risk remains significant given REDCap's extensive use in academic and clinical research environments.

The primary impact of CVE-2024-45527 is on user session integrity and confidentiality. Forced logout via CSRF can disrupt user workflows, potentially causing data loss or interruption in critical research activities. The ability to inject phishing links poses a risk of credential theft, malware infection, or further compromise through social engineering. While the vulnerability does not directly affect system availability or allow remote code execution, the manipulation of user sessions and potential redirection to malicious sites can undermine trust in the platform and expose sensitive research data indirectly. Organizations relying on REDCap for clinical trials, healthcare research, or academic studies may face operational disruptions and reputational damage if exploited. The lack of authentication requirements increases the attack surface, allowing remote attackers to target any user who interacts with the malicious project title content.

To mitigate CVE-2024-45527, organizations should implement strict input validation and output encoding for the project title field to prevent HTML injection. Applying Content Security Policy (CSP) headers can reduce the risk of executing injected scripts or loading malicious external resources. Administrators should monitor REDCap updates and apply official patches promptly once released. In the interim, restricting project creation permissions to trusted users can reduce exposure. Educating users to recognize suspicious links and avoid interacting with untrusted project titles can help mitigate phishing risks. Additionally, implementing anti-CSRF tokens and verifying the origin of logout requests can prevent forced logout attacks. Regular security audits and penetration testing focused on input handling will help identify similar vulnerabilities proactively.
