Multiple Vulnerabilities in Rsync Could Allow for Remote Code Execution

Read Time:39 Second

Multiple vulnerabilities have been discovered in Rsync, the most severe of which could allow for remote code execution. Rsync is an open-source file synchronization and data transferring tool valued for its ability to perform incremental transfers, reducing data transfer times and bandwidth usage. The tool is utilized extensively by backup systems like Rclone, DeltaCopy, ChronoSync, public file distribution repositories, and cloud and server management operations. Successful exploitation of the most severe of these vulnerabilities could allow for remote code execution in the context of the system. Depending on the privileges associated with the system, an attacker could then install programs; view, change, or delete data. Users whose accounts are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights.
