CVE-2022-3067 is a medium-severity vulnerability affecting GitLab Community Edition (CE) and Enterprise Edition (EE) versions starting from 14.4 up to but not including 15.2.5, versions from 15.3 up to but not including 15.3.4, and versions from 15.4 up to but not including 15.4.1. The vulnerability resides in the Import functionality of GitLab, where improper access control allows an authenticated user to read arbitrary project content by specifying the project's ID. This means that any user with valid credentials, regardless of their permission level, could potentially access the contents of projects they are not authorized to view. The vulnerability is classified under CWE-284 (Improper Access Control), indicating that the system fails to restrict access to resources properly. The CVSS v3.1 base score is 6.5, reflecting a medium severity level, with the vector indicating network attack vector (AV:N), low attack complexity (AC:L), requiring privileges (PR:L), no user interaction (UI:N), unchanged scope (S:U), high confidentiality impact (C:H), no integrity impact (I:N), and no availability impact (A:N). No known exploits are reported in the wild, and no official patch links are provided in the data, but GitLab has presumably addressed this issue in versions 15.2.5, 15.3.4, and 15.4.1 and later. The vulnerability allows unauthorized disclosure of sensitive project data, which could include source code, configuration files, and other proprietary information, potentially leading to intellectual property theft or aiding further attacks.

For European organizations using GitLab for source code management and DevOps workflows, this vulnerability poses a significant risk to confidentiality. Unauthorized access to project repositories could lead to exposure of sensitive intellectual property, business logic, and potentially credentials or secrets stored within repositories. This could facilitate further attacks such as supply chain compromises, insider threats, or competitive espionage. Since GitLab is widely adopted across various industries in Europe, including finance, manufacturing, and government sectors, the impact could be broad. The vulnerability does not affect integrity or availability directly but compromises confidentiality, which is critical in regulated environments subject to GDPR and other data protection laws. Exposure of sensitive data could result in regulatory penalties, reputational damage, and loss of customer trust. The requirement for authentication limits exploitation to insiders or compromised accounts, but given the low attack complexity and lack of user interaction, attackers with valid credentials could exploit this vulnerability easily.

European organizations should immediately verify their GitLab versions and upgrade to the patched releases: 15.2.5 or later for the 14.4+ branch, 15.3.4 or later for the 15.3 branch, and 15.4.1 or later for the 15.4 branch. If immediate upgrading is not feasible, organizations should restrict access to GitLab instances by enforcing strict authentication and authorization policies, including multi-factor authentication (MFA) for all users. Review and tighten project visibility settings and user permissions to minimize the number of users with access to sensitive projects. Implement network-level controls such as IP whitelisting and VPN access to limit exposure. Conduct audits of user accounts and monitor logs for unusual access patterns to detect potential exploitation attempts. Additionally, consider isolating critical projects in separate GitLab instances or repositories with enhanced security controls. Regularly review GitLab security advisories and subscribe to vendor notifications to stay informed about updates and patches.
