CVE-2023-2589
Description
An issue has been discovered in GitLab EE affecting all versions starting from 12.0 before 15.10.8, all versions starting from 15.11 before 15.11.7, all versions starting from 16.0 before 16.0.2. An attacker can clone a repository from a public project, from a disallowed IP, even after the top-level group has enabled IP restrictions on the group.
Summary dbcve.org
GitLab EE allows attackers to bypass IP restrictions at the group level and clone repositories from public projects using disallowed IP addresses. The vulnerability exists in the IP restriction enforcement mechanism for group-level access controls.
Mitigation
Upgrade GitLab EE to version 15.10.8, 15.11.7, or 16.0.2 or later. Alternatively, if immediate upgrade is not possible, review and restrict public project visibility or implement additional network-level access controls.
