1. Risk Assessment
The vulnerability identified as CVE-2024-11176 is an improper access control issue in M-Files Aino, affecting versions prior to 24.10. This flaw allows an authenticated user to access object information due to incorrect calculation of effective permissions. The nature of this vulnerability lies in its ability to bypass intended access controls, potentially exposing sensitive data to unauthorized users.
The CVSS v4.0 base score of 5.3 (MEDIUM severity) indicates a moderate risk. The attack complexity is low, and no user interaction is required, making it relatively easy to exploit. The primary impact is on confidentiality, as unauthorized access to object information could lead to data exposure. Integrity and availability are not directly impacted by this vulnerability.
The likelihood of exploitation is moderate, given that the attack vector is network-based and requires low privileges. However, the EPSS score of 0.000430000 suggests a low probability of active exploitation in the wild. Despite this, the potential business impact is significant, particularly for organizations handling sensitive or proprietary information, as unauthorized access could lead to data breaches, regulatory non-compliance, and reputational damage.
2. Potential Attack Scenarios
An authenticated user with low privileges could exploit this vulnerability to gain unauthorized access to sensitive object information stored in M-Files Aino. The attack vector involves leveraging the incorrect calculation of effective permissions to bypass access controls.
The attack process begins with the attacker authenticating to the system using valid credentials. Once authenticated, the attacker exploits the flawed permission calculation mechanism to access objects they should not have permission to view. This could include confidential documents, intellectual property, or other sensitive data.
The potential outcomes of this attack include unauthorized data access, data leakage, and potential misuse of the exposed information. For organizations, this could result in financial losses, legal consequences, and damage to customer trust.
3. Mitigation Recommendations
The primary mitigation for this vulnerability is to update M-Files Aino to version 24.10 or later, as this version includes the necessary patches to address the improper access control issue. Organizations should prioritize this update to eliminate the risk of exploitation.
Additionally, organizations should review and audit user permissions to ensure that access controls are correctly configured and enforced. Implementing the principle of least privilege can further reduce the risk of unauthorized access.

4. Executive Summary
CVE-2024-11176 is a medium-severity vulnerability in M-Files Aino that allows authenticated users to bypass access controls and access sensitive object information. This flaw stems from an incorrect calculation of effective permissions, posing a risk to data confidentiality.
While the likelihood of exploitation is currently low, the potential business impact is significant, particularly for organizations handling sensitive data. Unauthorized access could lead to data breaches, regulatory penalties, and reputational harm.
To mitigate this risk, organizations should immediately update to M-Files Aino version 24.10 or later. Additionally, reviewing and tightening access controls can further reduce the risk of unauthorized data access. Addressing this vulnerability promptly is critical to safeguarding sensitive information and maintaining organizational security.
