Описание
Rclone is a command-line program to sync files and directories to and from different cloud storage providers. Starting in version 1.48.0 and prior to version 1.73.5, the RC endpoint operations/fsinfo is exposed without AuthRequired: true and accepts attacker-controlled fs input. Because rc.GetFs(...) supports inline backend definitions, an unauthenticated attacker can instantiate an attacker-controlled backend on demand. For the WebDAV backend, bearer_token_command is executed during backend initialization, making single-request unauthenticated local command execution possible on reachable RC deployments without global HTTP authentication. Version 1.73.5 patches the issue.
A flaw was found in Rclone, a command-line program for syncing files with cloud storage. An unauthenticated attacker can exploit an exposed Remote Control (RC) endpoint, operations/fsinfo, to instantiate a malicious backend. This allows the attacker to execute arbitrary local commands during backend initialization, leading to unauthenticated local command execution on reachable RC deployments.
Отчет
The vulnerable functionality exists in the RC server. Thus, for the vulnerability to be exploited, the RC server must be started, via rclone rcd or the --rc flag. Additionally, the RC server must be deployed without any required authentication. Because Red Hat products either do not include this functionality, or expose it only to localhost, Red Hat assesses the impact of this vulnerability as Important.
