CVE-2022-38599: n/a in n/a
Teleport v3.2.2, Teleport v3.5.6-rc6, and Teleport v3.6.3-b2 was discovered to contain an information leak via the /user/get-role-list web interface.
AI Analysis
Technical Summary
CVE-2022-38599 is a medium-severity information disclosure vulnerability affecting specific versions of Teleport, namely v3.2.2, v3.5.6-rc6, and v3.6.3-b2. Teleport is a widely used open-source tool that provides secure access to infrastructure such as SSH servers, Kubernetes clusters, and internal web applications. The vulnerability arises from an information leak via the /user/get-role-list web interface endpoint. This endpoint, when accessed, improperly exposes sensitive role-related information that should be restricted. The vulnerability is classified under CWE-668 (Exposure of Resource to Wrong Sphere), indicating that the system exposes resources or information to unauthorized parties due to improper access control or validation. According to the CVSS v3.1 vector (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N), the attack vector is network-based, requires low attack complexity, and requires privileges (PR:L) but no user interaction. The impact is high on confidentiality, with no impact on integrity or availability. No known exploits are currently reported in the wild, and no official patches or vendor advisories are linked in the provided data. The vulnerability allows an authenticated user with some privileges to retrieve sensitive role information, which could facilitate further privilege escalation or targeted attacks within the affected infrastructure. Given the nature of Teleport as a critical access management tool, leaking role information can undermine security policies and expose organizational access structures to adversaries.
Potential Impact
For European organizations, the impact of CVE-2022-38599 can be significant, especially for those relying on Teleport for secure access to internal systems and cloud infrastructure. Disclosure of role information can enable attackers or malicious insiders to map out user privileges and roles, aiding in lateral movement and privilege escalation attacks. This can lead to unauthorized access to sensitive data, disruption of operations, or compromise of critical infrastructure. Sectors such as finance, healthcare, government, and critical infrastructure operators in Europe, which often use Teleport or similar access management tools, may face increased risk. The leak of role information could also contravene GDPR requirements related to data protection and access controls, potentially resulting in regulatory penalties. Although the vulnerability requires some level of authentication, organizations with weak internal controls or exposed Teleport instances may be at higher risk. The absence of known exploits reduces immediate risk but does not eliminate the threat, as attackers may develop exploits over time.
Mitigation Recommendations
1. Immediate mitigation should include restricting access to the /user/get-role-list endpoint to only highly trusted and necessary users, implementing strict network segmentation and firewall rules to limit access to Teleport management interfaces. 2. Enforce the principle of least privilege rigorously within Teleport, ensuring that users have only the minimum roles necessary for their tasks, reducing the impact of any information disclosure. 3. Monitor and audit access logs for unusual or unauthorized attempts to access role information or the vulnerable endpoint. 4. Upgrade Teleport to versions beyond v3.6.3-b2 once official patches or fixed releases are available; in the meantime, consider applying any community or vendor-provided workarounds or configuration changes that disable or protect the vulnerable endpoint. 5. Implement multi-factor authentication (MFA) for all Teleport users to reduce the risk of compromised credentials being used to exploit this vulnerability. 6. Conduct internal penetration testing and vulnerability assessments focusing on Teleport deployments to identify and remediate any exposure. 7. Educate administrators and users about the sensitivity of role information and the importance of safeguarding access credentials and interfaces.
