What is the Vulnerability?Teleport security engineers have discovered a critical vulnerability affecting Teleport versions earlier than 17.5.2. This flaw allows remote attackers to bypass SSH authentication on servers running Teleport SSH agents, OpenSSH-integrated deployments, and Teleport Git proxy setups. Exploiting this vulnerability could enable unauthorized access to Teleport-managed systems by circumventing standard authentication controls. View more information on the Community Article posted by FortiCNAPP. [FortiCNAPP – Fortinet Community]Teleport is an open-source platform that provides zero trust access to servers and cloud applications through protocols such as SSH, Kubernetes, databases, Remote Desktop Protocol (RDP), and HTTPS.Currently, there is no public proof-of-concept exploit available, nor any evidence indicating that this vulnerability has been exploited in the wild.What is the recommended Mitigation?To mitigate this vulnerability, self-hosted Teleport users should immediately upgrade Teleport Proxy and SSH services to one of the following versions: 17.5.2, 16.5.12, 15.5.3, 14.4.1, 13.4.27, or 12.4.35.According to the vendor, Teleport Cloud Infrastructure and CI\/CD build, test, and release infrastructure aren\u2019t affected.
