This article discusses various known attack surfaces and potential risks associated with GitLab, highlighting a range of vulnerabilities, including Remote Code Execution (RCE), SSRF, XSS, and permission escalation issues. The information covers the history of vulnerabilities, their impact, and famous cases, emphasizing the importance of security measures for self-managed GitLab instances. Affected: GitLab
Keypoints :
- GitLab has experienced numerous security vulnerabilities over the years, including RCE, SSRF, XSS, and permission escalation.
- Vulnerabilities can allow attackers to control GitLab servers or access sensitive data.
- Several critical vulnerabilities (CVE-2021-22205, CVE-2022-2884, etc.) demonstrate varying authentication requirements and exploit methodologies.
- Common types of attacks include SSRF allowing unauthorized access to internal resources and XSS that can hijack administrator sessions.
- Path traversal vulnerabilities can lead to arbitrary file reading or writing, facilitating RCE or privilege escalation.
- The complexity of GitLab’s CI/CD functionalities presents new potential vulnerabilities.
- Third-party components and integrations also pose risks if not properly secured.
MITRE Techniques :
- Remote Code Execution (RCE) – Attackers exploit vulnerabilities in GitLab to execute arbitrary code on the server.
- Server-Side Request Forgery (SSRF) – Attackers trick the server into sending requests to internal network resources.
- Cross-Site Scripting (XSS) – Attackers inject malicious scripts into web pages that are viewed by other users, enabling account hijacking.
- Path Traversal (T1133) – Attackers can manipulate file paths to read sensitive files or write data to unauthorized locations.
- Privilege Escalation (T1044) – Exploiting logic flaws to gain elevated access rights beyond the intended permissions.
