CyberRota Analysis
AI-GeneratedAuthenticated users with SFTP permissions in JumpServer versions 4.8.0 to 4.10.17 can exploit a path traversal vulnerability through the KoKo Web Terminal SFTP feature, allowing unauthorized access to files outside the intended SFTP root. This could lead to unauthorized read, write, rename, or delete operations on the asset's backend account. Organizations using affected versions should prioritize upgrading to version 4.10.17 to mitigate potential security risks.

Original NVD Description
JumpServer is an open source bastion host and an operation and maintenance security audit system. From 4.8.0 until 4.10.17, an authenticated user with SFTP permission to an authorized asset can submit crafted traversal paths through the KoKo Web Terminal SFTP feature, causing AssetDir.GetRealPath() in pkg/srvconn/sftp_asset.go to resolve paths outside the intended SFTP root and permit read, list, write, rename, or delete operations under the configured backend account on that asset. This issue is fixed in version 4.10.17.
