Overview
CVE-2024-9183 is a high-severity vulnerability affecting GitLab CE/EE. It allows an authenticated, lower-privileged user, under specific circumstances, to potentially obtain credentials from higher-privileged users and perform actions within their context. This could lead to significant security breaches, including data exfiltration and unauthorized access.
This vulnerability affects all versions of GitLab CE/EE from 18.4 prior to 18.4.5, 18.5 prior to 18.5.3, and 18.6 prior to 18.6.1. It has been remediated in versions 18.4.5, 18.5.3, and 18.6.1 and later.
Technical Details
The precise technical details of the vulnerability are not explicitly detailed here to prevent further exploitation. However, it is understood that the vulnerability involves a flaw in how GitLab handles user authentication and session management. Under specific conditions, a lower-privileged user could exploit this flaw to intercept or reconstruct credentials belonging to users with elevated permissions. These specific conditions likely involve a particular sequence of actions or interactions within the GitLab platform. Refer to the linked GitLab issue for complete details (see References section).
CVSS Analysis
The vulnerability has been assigned a CVSS score of 7.7, indicating a high severity level.
- CVSS Score: 7.7
- Severity: HIGH
This score reflects the potential for significant impact, including unauthorized access to sensitive data and system compromise.
Possible Impact
The successful exploitation of CVE-2024-9183 could have severe consequences, including:
- Data Breach: Unauthorized access to sensitive data stored within GitLab projects, potentially including source code, credentials, and other confidential information.
- Privilege Escalation: An attacker gaining the ability to perform actions as a higher-privileged user, such as administrator, leading to full control over the GitLab instance.
- Code Injection: The ability to inject malicious code into projects, leading to supply chain attacks or other forms of compromise.
- Service Disruption: Disruption of GitLab services due to unauthorized modifications or data corruption.
Mitigation and Patch Steps
The most effective way to mitigate the risk of CVE-2024-9183 is to upgrade your GitLab instance to one of the following versions:
- 18.4.5 or later
- 18.5.3 or later
- 18.6.1 or later
It is strongly recommended to apply these updates as soon as possible to protect your GitLab instance from potential exploitation. Follow the official GitLab upgrade documentation for detailed instructions.
