Описание
Rclone is a command-line program to sync files and directories to and from different cloud storage providers. Prior to 1.74.4, rclone archive extract can write extracted files outside the user-selected destination prefix when extracting a crafted archive containing parent path components such as ../, allowing creation or overwrite of sibling objects in the same bucket or path scope. This issue is fixed in version 1.74.4.
A flaw was found in rclone, a command-line program for managing cloud storage. An attacker could craft a malicious archive that, when extracted by a user, allows files to be written outside the intended destination directory. This path traversal vulnerability could lead to the creation or overwrite of other files within the same storage location, potentially compromising data integrity.
Отчет
Red Hat ships rclone in the VolSync component of Red Hat Advanced Cluster Management for Kubernetes (RHACM). All shipped versions are affected by this path traversal vulnerability in rclone's archive extraction functionality. Exploitation requires a user to actively run rclone archive extract on an attacker-supplied malicious archive.
Меры по смягчению последствий
Do not use rclone archive extract to extract archives from untrusted or unverified sources. If archive extraction is required, inspect the archive contents first using rclone archive list to check for suspicious path components (e.g., ../).
