Description

An issue was discovered in rsync before 3.2.5 that allows malicious remote servers to write arbitrary files inside the directories of connecting peers. The server chooses which files/directories are sent to the client. However, the rsync client performs insufficient validation of file names. A malicious rsync server (or Man-in-The-Middle attacker) can overwrite arbitrary files in the rsync client target directory and subdirectories (for example, overwrite the .ssh/authorized_keys file).

Affected products

• Fedoraproject Fedora: 35, 36
• RsyncProject rsync: before 3.2.5 — fixed in 3.2.5

How to fix

Upgrade to a fixed version: RsyncProject rsync 3.2.5. Check the vendor advisory for mitigations.
