Detailsinfo

A vulnerability classified as critical has been found in rsync up to 3.2.4 (File Transfer Software). This affects an unknown code block of the component File Name Handler. The manipulation with an unknown input leads to a channel accessible vulnerability. CWE is classifying the issue as CWE-300. The product does not adequately verify the identity of actors at both ends of a communication channel, or does not adequately ensure the integrity of the channel, in a way that allows the channel to be accessed or influenced by an actor that is not an endpoint. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

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).

The weakness was disclosed 08/02/2022. The advisory is shared at openwall.com. This vulnerability is uniquely identified as CVE-2022-29154. Neither technical details nor an exploit are publicly available. MITRE ATT&CK project uses the attack technique T1557 for this issue.
