CVE-2024-9333 is a vulnerability classified under CWE-281, indicating improper preservation of permissions within the M-Files Connector for Copilot product by M-Files Corporation. This flaw exists in versions prior to 24.9.3 and allows authenticated users with limited privileges to bypass intended access controls. The root cause is an incorrect calculation of the access control list (ACL), which governs document access permissions. As a result, users can access a limited number of documents they should not have permission to view. The vulnerability does not require user interaction and can be exploited remotely by any authenticated user with low privileges, making it relatively easy to exploit within an environment where user accounts exist. The CVSS 4.0 base score is 5.3 (medium severity), reflecting network attack vector, low attack complexity, no privileges required beyond authentication, and limited confidentiality impact. There is no indication of integrity or availability impact. No public exploits have been reported yet, and no patches are linked in the provided data, but updating to version 24.9.3 or later is recommended once available. This vulnerability primarily threatens confidentiality by exposing sensitive documents to unauthorized users, potentially leading to data leakage or compliance violations.

The primary impact of CVE-2024-9333 is unauthorized disclosure of sensitive documents due to improper access control enforcement. Organizations using affected versions of M-Files Connector for Copilot risk exposure of confidential information to authenticated users who should not have access. This can lead to data breaches, intellectual property theft, and regulatory compliance issues, especially in industries handling sensitive or regulated data such as finance, healthcare, legal, and government sectors. Although the scope of document exposure is limited, even partial data leakage can have significant reputational and financial consequences. Since exploitation requires only authenticated access with low privileges, insider threats or compromised low-level accounts can leverage this vulnerability. The lack of impact on integrity and availability reduces the risk of data manipulation or service disruption but does not diminish the confidentiality risk. Organizations globally that rely on M-Files for document management and collaboration are potentially affected, with greater risk in environments with many users and sensitive documents.

Organizations should prioritize upgrading M-Files Connector for Copilot to version 24.9.3 or later once the patch is released by M-Files Corporation. Until a patch is available, administrators should implement strict user access controls and monitor user activities to detect unusual document access patterns. Employing the principle of least privilege to limit user permissions reduces the risk of exploitation. Conduct regular audits of document access logs to identify unauthorized access attempts. Network segmentation and strong authentication mechanisms, such as multi-factor authentication (MFA), can help reduce the risk of compromised accounts being used to exploit this vulnerability. Additionally, organizations should educate users about the importance of safeguarding credentials and monitor for insider threat indicators. Coordinating with M-Files support for timely updates and guidance is recommended. Finally, consider implementing data loss prevention (DLP) tools to detect and prevent unauthorized data exfiltration.
