Описание
Rclone is a command-line program to sync files and directories to and from different cloud storage providers. The RC endpoint options/set is exposed without AuthRequired: true, but it can mutate global runtime configuration, including the RC option block itself. Starting in version 1.45.0 and prior to version 1.73.5, an unauthenticated attacker can set rc.NoAuth=true, which disables the authorization gate for many RC methods registered with AuthRequired: true on reachable RC servers that are started without global HTTP authentication. This can lead to unauthorized access to sensitive administrative functionality, including configuration and operational RC methods. Version 1.73.5 patches the issue.
A flaw was found in Rclone, a command-line program designed for synchronizing files with various cloud storage providers. An unauthenticated attacker can exploit an exposed Remote Control (RC) endpoint, options/set, to disable the authorization mechanism for other RC methods. This vulnerability allows the attacker to gain unauthorized access to sensitive administrative functionality, including configuration and operational control of the Rclone server.
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.
