CyberRota Analysis
AI-GeneratedRclone versions 1.70.0 to 1.75.1 are vulnerable due to improper handling of authentication proxy settings in the serve/start RC interface, which can lead to unauthorized access through default credentials for FTP and S3 services. This critical vulnerability allows attackers to exploit the fallback mechanism, potentially exposing sensitive data. Organizations using affected versions of rclone for cloud storage synchronization should prioritize upgrading to version 1.75.1 to mitigate this risk.

Original NVD Description
rclone is a command-line program to sync files and directories to and from different cloud storage providers. From 1.70.0 until 1.75.1, the serve/start RC interface accepts per-server proxyOpt.AuthProxy settings, and the FTP and S3 constructors in cmd/serve/ftp/ftp.go and cmd/serve/s3/server.go incorrectly check the process-global proxy.Opt.AuthProxy value instead. When the global value is empty, the request-local authentication proxy is ignored: FTP falls back to the fixed filesystem with username anonymous and any password, while S3 with AuthKey serves the fixed RC fs rather than the backend selected by the proxy. The dedicated command-line servers that configure the global option are not affected. This issue is fixed in version 1.75.1.
