Email Password Reset Vulnerability Affects GitLab Versions

What is CVE-2023-7028?

CVE-2023-7028 is a vulnerability identified in GitLab, a popular platform used for software development and version control. The issue affects multiple versions of GitLab Community Edition and Enterprise Edition, which are utilized by organizations for managing code repositories and facilitating collaboration among developers. This vulnerability permits user account password reset emails to be sent to unverified email addresses, potentially enabling unauthorized access to accounts. Such unauthorized access could have severe implications for an organization’s security posture, leading to data breaches or compromise of sensitive projects.

Technical Details

The vulnerability impacts GitLab versions ranging from 16.1 to 16.7, specifically those prior to updates 16.1.6, 16.2.9, 16.3.7, 16.4.5, 16.5.6, 16.6.4, and 16.7.2. It arises from the failure of the system to properly validate email addresses used in the password reset process. As a result, an attacker can manipulate this process, directing reset emails to any email address of their choice, regardless of verification status. This flaw may allow attackers to hijack user accounts if they gain access to the email account receiving the reset link.

Impact of the Vulnerability

1. Unauthorized Account Access: Attackers can exploit the vulnerability to gain unauthorized access to user accounts, posing a significant risk to sensitive information and project integrity.

2. Data Breach Potential: Once an account is compromised, attackers could access confidential data, intellectual property, and sensitive project details, leading to potential data breaches that could have legal and reputational repercussions for the organization.

3. Increased Risk of Further Exploitation: With access to compromised accounts, attackers may initiate further attacks, including deployment of malware, unauthorized changes to code repositories, or lateral movements within the organization’s systems, thereby amplifying the overall security threat.
