Amazon Linux 2 : rsync (ALAS-2022-1873)

high Nessus Plugin ID 167228

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of rsync installed on the remote host is prior to 3.1.2-11. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2022-1873 advisory.

A flaw was found in rsync that is triggered by a victim rsync user/client connecting to a malicious rsync server. The server can copy and overwrite arbitrary files in the client's rsync target directory and subdirectories. This flaw allows a malicious server, or in some cases, another attacker who performs a man-in-the-middle attack, to potentially overwrite sensitive files on the client machine, resulting in further exploitation. (CVE-2022-29154)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Run 'yum update rsync' to update your system.
