CVE-2024-0231 - Resource Misdirection Vulnerability in GitLab CE/EE: Exploiting Repository Imports

GitLab CE/EE, the widely used web-based application for Git repository management, has been discovered to contain a resource misdirection vulnerability. This vulnerability, known as CVE-2024-0231, affects GitLab CE/EE versions 12. prior to 17..5, 17.1 prior to 17.1.3, and 17.2 prior to 17.2.1. An attacker who successfully exploits this vulnerability could mislead the GitLab software into committing a repository import in a wrongful direction, potentially causing harm to the application's data or stability.

This post will elaborate on the nature of this vulnerability, illustrate how attackers can exploit it by crafting malicious repository imports, and provide original reference material for readers to review and understand the issue. We will also discuss possible mitigation strategies for users and administrators.
