CyberRota Analysis
AI-GeneratedRclone versions prior to 1.75.1 are vulnerable to a symlink attack that allows an attacker to manipulate file and directory metadata outside the intended destination by exploiting the --links option with a .rclonelink object. This can lead to unauthorized changes in ownership, permissions, and timestamps, potentially compromising the integrity of the file system. Organizations using rclone for cloud storage synchronization should prioritize upgrading to version 1.75.1 to mitigate this high-severity vulnerability.

Original NVD Description
rclone is a command-line program to sync files and directories to and from different cloud storage providers. Prior to 1.75.1, when backend/local runs with --links, a source .rclonelink object can plant a symlink in the destination and later directory metadata is applied through that path. MkdirMetadata, writeMetadataToFile, and setTimes operate when Directory.translatedLink=false, so os.Chown, os.Chmod, os.Chtimes, and birth-time handling can bypass os.Root confinement and follow the symlink. An attacker controlling source contents can therefore apply selected ownership, permissions, modification times, or birth times to a file or directory outside the destination, with --metadata required for chmod and chown while modification time is applied by the normal directory workflow. This issue is fixed in version 1.75.1.
