CVE-2023-5009 is a high-severity vulnerability affecting GitLab EE versions prior to 16.2.7 and 16.3.4. This vulnerability allows attackers to run pipeline jobs as arbitrary users through scheduled security scan policies, effectively bypassing previous protections established in CVE-2023-3932. Organizations utilizing these versions of GitLab must prioritize remediation to prevent potential unauthorized access.
With a CVSS score of 8.2, this vulnerability poses a significant risk due to its high impact on confidentiality and integrity. The attack vector is network-based, requiring low privileges and no user interaction, making it particularly dangerous for organizations that have not yet patched affected versions.
Organizations should prioritize patching immediately to mitigate potential threats arising from this vulnerability. The urgency is underscored by the potential for attackers to leverage this flaw to execute unauthorized actions within the GitLab environment.
The publication date of this CVE was September 19, 2023. Given its implications, it is essential for organizations to assess their exposure and take appropriate action without delay.
Vulnerability Details
This vulnerability allows an attacker to run pipeline jobs as an arbitrary user via scheduled security scan policies. The affected versions are all GitLab EE versions from 13.12 before 16.2.7 and from 16.3 before 16.3.4. This issue has a CVSS score of 8.2, classified under high severity.
The CWE classification associated with this vulnerability is CWE-863, indicating an issue with improper authorization. Organizations using affected GitLab versions are strongly encouraged to apply the latest patches to mitigate this risk.
Technical Analysis
The root cause of CVE-2023-5009 lies in the implementation of scheduled security scan policies that do not adequately restrict user privilege levels during pipeline job execution. This oversight allows unauthorized users to exploit the system and execute jobs that should be reserved for legitimate users.
The attack vector is network-based, requiring no user interaction, making it easier for attackers to exploit. The attack complexity is rated as high, indicating that an attacker would need to understand the specific configurations of the GitLab environment.
In terms of impact, the vulnerability poses a high confidentiality and integrity risk, while availability remains unaffected. Organizations must be aware of the potential for data breaches and unauthorized actions that could compromise sensitive information.
Risk & Impact Analysis
Risk to organizations includes unauthorized access to sensitive data and execution of unauthorized commands within the GitLab environment. The potential blast radius is significant, especially for organizations using GitLab for critical CI/CD processes. Organizations should assess their deployment configurations and patch the affected versions to prevent exploitation.
The urgency for remediation is high given the CVSS score of 8.2, indicating that organizations should address this vulnerability in their priority patch cycle. Failure to do so could lead to severe security breaches and loss of sensitive data.
