Authentication Bypass by Spoofing in GitLab (CVE-2024-6678)
A critical authentication bypass vulnerability (CVE-2024-6678) exists in GitLab CE/EE that affects multiple version ranges. This flaw allows an attacker to trigger a pipeline as an arbitrary user under certain conditions. The issue impacts versions from 8.14 up to but not including 17.1.7, from 17.2 up to but not including 17.2.5, and from 17.3 up to but not including 17.3.2. A patch is available to remediate this vulnerability.
AI Analysis
Technical Summary
CVE-2024-6678 is an authentication bypass vulnerability in GitLab Community and Enterprise Editions. It affects all versions starting from 8.14 prior to 17.1.7, from 17.2 prior to 17.2.5, and from 17.3 prior to 17.3.2. The vulnerability allows an attacker to trigger a pipeline as an arbitrary user under certain circumstances, effectively bypassing authentication controls. This could lead to unauthorized pipeline executions with the privileges of the spoofed user. The vendor has released patches for the affected versions to address this issue.
Potential Impact
An attacker exploiting this vulnerability can bypass authentication mechanisms to trigger pipelines as arbitrary users. This unauthorized action could lead to execution of code or processes with the privileges of the targeted user, potentially compromising the integrity and security of the affected GitLab instance.
Mitigation Recommendations
A patch is available for this vulnerability. Users should upgrade to GitLab versions 17.1.7 or later, 17.2.5 or later, or 17.3.2 or later to remediate this issue. Applying the official fixes from the vendor is the recommended mitigation.
