CyberRota Analysis

AI-Generated

Rclone versions prior to 1.75.0 are vulnerable to transport downgrade attacks during redirect handling, which can lead to the exposure of Basic authorization and Cookie headers over unencrypted HTTP. This allows an on-path attacker to capture and replay credentials, potentially enabling unauthorized WebDAV operations with the affected account's permissions. Organizations using rclone for file synchronization or cloud storage should prioritize this vulnerability to mitigate the risk of credential theft and unauthorized access.

Original NVD Description

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.
