Security News > 2024 > January > Patch time: Critical GitLab vulnerability exposes 2FA-less users to account takeovers
Attackers targeting vulnerable self-managed GitLab instances could use a specially crafted HTTP request to send a password reset email to an attacker-controlled, unverified email address.
Users with 2FA enabled aren't vulnerable to account takeover, unless the attacker also had control of the 2FA authenticator, but a password reset could still be achieved.
GitLab doesn't support SMS-based 2FA - the most commonly hijacked implementation - only supporting app-based 2FA or that issued via a WebAuthn device, which are much more secure.
A takeover of a GitLab account could mean serious business for attackers, given the amount of intellectual property and source code belonging to organizations held in the DevOps platform.
CVE-2023-6955: An improper access control vulnerability exists in GitLab Remote Development affecting all versions prior to 16.5.6, 16.6 prior to 16.6.4 and 16.7 prior to 16.7.2.
CVE-2023-2030: An issue has been discovered in GitLab CE/EE affecting all versions from 12.2 prior to 16.5.6, 16.6 prior to 16.6.4, and 16.7 prior to 16.7.2 in which an attacker could potentially modify the metadata of signed commits.
