Summary
rclone versions before v1.75.0 fail to reject transport downgrades in redirect handling, allowing Basic authorization and Cookie headers to be replayed over plaintext HTTP after same-host HTTPS-to-HTTP redirects.
An on-path attacker observing the plaintext hop can capture and reuse credentials to perform WebDAV operations with the compromised account's permissions. A flaw was found in rclone.
Red Hat severity: Moderate — CVSS 5.3 (CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N). Weakness: CWE-523.
Affected Red Hat products: Cryostat 4; Red Hat Advanced Cluster Management for Kubernetes 2. Red Hat does not currently list a fixing RHSA for this CVE.
