CVE-2024-7060: Information Disclosure Vulnerability in GitLab CE/EE Project/Group Exports

A newly discovered vulnerability with the code identifier CVE-2024-7060 affects GitLab, a popular web-based DevOps lifecycle tool. This information disclosure vulnerability is capable of impacting all existing GitLab versions (Community Edition & Enterprise Edition) from 15.4 to 17..5, 17.1, and 17.2.1. More specifically, the vulnerability allows unauthorized users to view exported project or group files. This breach of confidentiality may lead to unintended recipients gaining access to sensitive information, posing a significant risk to affected users.

Code Snippet

The security flaw is a result of improper access controls within the GitLab export mechanism. The export process permits unauthorized users to view exported files by simply requesting the data or through a specially crafted link.

Here is an example of how this vulnerability could potentially be exploited

https://gitlab.example.com/groups/example-group/-/exports/download?export_id=2orca9f

In this example, an attacker could access the "example-group" group export even without proper authorization.

Official References

The vulnerability has been officially acknowledged and confirmed by GitLab, and the company has promptly provided patches to fix the issue. The appropriate patches can be found at the following links:

- GitLab 17..5: https://gitlab.com/gitlab-org/gitlab/-/releases/17..5

- GitLab 17.2.1: https://gitlab.com/gitlab-org/gitlab/-/releases/17.2.1

To avoid exploitation by unauthorized users and protect sensitive information from being compromised, it is strongly advised that all GitLab users and administrators update to the latest patched versions available in the links above.

Exploit Details

The primary exploit technique involves intercepting or crafting a URL that grants unauthorized access to project or group exports. By using the vulnerable version of GitLab, an attacker can more easily obtain sensitive data from exported files. The consequences of such a breach could include unauthorized access to proprietary code, credentials, or other confidential information, potentially leading to further exploitation and system compromise.

Mitigation and Recommendations

The best course of action in order to protect against this vulnerability is to update GitLab to the latest patched version which addresses the security flaw. GitLab has released the following updates to resolve the issue:

GitLab 17.2.1

Additionally, it is important to implement proper access controls and continuously monitor system logs to identify any attempts to exploit this vulnerability. In order to safeguard your GitLab instance from future potential threats, it is recommended to maintain regular updates, perform vulnerability scans, and enforce strong authentication and authorization mechanisms.

Conclusion

CVE-2024-7060 is an information disclosure vulnerability that affects various versions of GitLab (Community Edition and Enterprise Edition) and allows unauthorized users to view sensitive exported data. With the release of these patches, GitLab demonstrates its commitment to swiftly addressing security threats. Users and administrators should promptly update their GitLab instances and implement security best practices to protect their valuable information from unauthorized access and potential compromise.
