Summary
Rclone is a command-line program to sync files and directories to and from different cloud storage providers.
Prior to 1.74.4, rclone serve restic --private-repos enforces authorization using the routed user path segment while building the backend object key from the raw uncleaned URL path, allowing an authenticated user to include.. in a request such as //..//config and read, overwrite, or delete another user's private repository on backends that clean path components.
This issue is fixed in version 1.74.4. A flaw was found in Rclone.
This vulnerability can lead to significant information disclosure, data integrity issues, and denial of service for other users' data. By using directory traversal sequences in requests, an attacker can access, modify, or delete other users' private repositories.
Red Hat severity: Moderate — CVSS 7.5 (CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H). Weakness: CWE-22.
