A business logic issue in the handling of large repositories in all versions of GitLab CE/EE from 10.0 before 15.1.6, all versions starting from 15.2 before 15.2.4, all versions starting from 15.3 before 15.3.2 allowed an authenticated and authorized user to exhaust server resources by importing a malicious project.

Weakness

The product does not properly control the allocation and maintenance of a limited resource.

Affected Software

Name Vendor Start Version End Version
Gitlab Gitlab 10.0.0 (including) 15.1.6 (excluding)
Gitlab Gitlab 15.2 (including) 15.2.4 (excluding)
Gitlab Gitlab 15.3 (including) 15.3.2 (excluding)
Gitlab Ubuntu esm-apps/xenial *
Gitlab Ubuntu upstream *

Potential Mitigations

  • Mitigation of resource exhaustion attacks requires that the target system either:

  • The first of these solutions is an issue in itself though, since it may allow attackers to prevent the use of the system by a particular valid user. If the attacker impersonates the valid user, they may be able to prevent the user from accessing the server in question.

  • The second solution is simply difficult to effectively institute – and even when properly done, it does not provide a full solution. It simply makes the attack require more resources on the part of the attacker.
