CyberRota Analysis

AI-Generated

Rclone versions prior to 1.75.0 are susceptible to a denial of service vulnerability in the WebDAV TUS creation handler, which can be exploited by a malicious endpoint to cause connection resets during uploads. This results in a panic that terminates unrecovered goroutines, potentially disrupting long-lived processes. Organizations using rclone for file transfers, especially those relying on WebDAV, should prioritize upgrading to mitigate this risk.

Original NVD Description

rclone before v1.75.0 contains a denial of service vulnerability in the WebDAV TUS creation handler that dereferences a nil response before checking for transport errors. A malicious or compromised configured endpoint can reset connections during TUS uploads to trigger a panic that terminates unrecovered goroutines and halts unrelated work in long-lived processes.
