4.3 · MEDIUMOverview
CVE-2025-27095 is a medium-severity vulnerability affecting fit2cloud jumpserver. It was published on March 31, 2025 and has a CVSS 3.1 base score of 4.3 (MEDIUM).
This vulnerability has a CVSS 3.1 base score of 4.3, rated MEDIUM. It can be exploited remotely over the network. Some level of privileges is required for exploitation.
Technical Description
JumpServer is an open source bastion host and an operation and maintenance security audit system. Prior to 4.8.0 and 3.10.18, an attacker with a low-privileged account can access the Kubernetes session feature and manipulate the kubeconfig file to redirect API requests to an external server controlled by the attacker. This allows the attacker to intercept and capture the Kubernetes cluster token. This can potentially allow unauthorized access to the cluster and compromise its security. This vulnerability is fixed in 4.8.0 and 3.10.18.
Remediation
Check the references section for vendor advisories and patches from fit2cloud. Update jumpserver to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
