一、漏洞信息
漏洞编号:CVE-2022-29154
漏洞归属组件:rsync
漏洞归属的版本:3.1.3,3.2.1,3.2.3,3.2.5
CVSS V3.0分值:
BaseScore:7.4 High
Vector:CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:H
漏洞简述:
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).
