An information disclosure vulnerability exists in GitLab CE/EE <v12.3.2, <v12.2.6, and <v12.1.12 that allowed project milestones to be disclosed via groups browsing.

Weakness

The product does not implement sufficient measures to prevent multiple failed authentication attempts within a short time frame, making it more susceptible to brute force attacks.

Affected Software

Name Vendor Start Version End Version
Gitlab Gitlab * 12.1.12 (excluding)
Gitlab Gitlab 12.2.0 (including) 12.2.6 (excluding)
Gitlab Gitlab 12.3.0 (including) 12.3.2 (excluding)

Potential Mitigations

  • Common protection mechanisms include:

  • Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.

  • Consider using libraries with authentication capabilities such as OpenSSL or the ESAPI Authenticator. [REF-45]
