RClone 1.59.x < 1.68.2 Privilege Escalation (macOS)

medium Nessus Plugin ID 211735

Language:

Synopsis

An application installed on the remote macOS / Mac OS X host is affected by a privilege escalation vulnerability.

Description

The version of rclone installed on the remote macOS / Mac OS X host is prior to 1.68.2. It is, therefore, affected by a privilege escalation vulnerability due to insecure handling of symlinks with --links and --metadata while copying to local disk. This vulnerability could allow unprivileged users to indirectly modify ownership and permissions on symlink target files when a superuser or privileged process performs a copy. This vulnerability could enable privilege escalation and unauthorized access to critical system files (e.g., /etc/shadow), compromising system integrity, confidentiality, and availability. An unprivileged user can create a symlink to /etc/sudoers, /etc/shadow or similar and wait for a privileged user or process to copy/backup/mirror users data (using --links and --metadata) resulting in the unprivileged user now owning the file symlinked to.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to rclone to version 1.68.2 or later.
