CVSS: 7.4EPSS: 0%CPEs: 3EXPL: 2CVE-2022-29154 – rsync: remote arbitrary files write inside the directories of connecting peers
https://notcve.org/view.php?id=CVE-2022-29154
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). Se ha detectado un problema en rsync versiones anteriores a 3.2.5, que permite a servidores remotos maliciosos escribir archivos arbitrarios dentro de los directorios de los pares conectados. • https://github.com/EgeBalci/CVE-2022-29154 http://www.openwall.com/lists/oss-security/2022/08/02/1 https://github.com/WayneD/rsync/tags https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/NMBOJ77A7T7PQCARMDUK75TE6LLESZ3O https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/YRQAI7H4M4RQZ2IWZUEEXECBE5D56BH2 https://access.redhat.com/security/cve/CVE-2022-29154 https://bugzilla.redhat.com/show_bug.cgi?id=2110928 • CWE-20: Improper Input Validation CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •

The parse_arguments function in options.c in rsyncd in rsync before 3.1.3 does not prevent multiple --protect-args uses, which allows remote attackers to bypass an argument-sanitization protection mechanism. La función parse_arguments en options.c en rsync, en versiones anteriores a la 3.1.3, no evita los usos múltiples de --protect-args, lo que permite que atacantes remotos omitan un mecanismo de protección de saneamiento de argumentos. • http://www.securityfocus.com/bid/102803 http://www.securitytracker.com/id/1040276 https://download.samba.org/pub/rsync/src-previews/rsync-3.1.3pre1-NEWS https://git.samba.org/rsync.git/?p=rsync.git%3Ba=commit%3Bh=7706303828fcde524222babb2833864a4bd09e07 https://lists.debian.org/debian-lts-announce/2018/01/msg00021.html https://lists.debian.org/debian-lts-announce/2019/03/msg00027.html https://lists.debian.org/debian-lts-announce/2021/11/msg00028.html https://security.gentoo.org/glsa/ •

The recv_files function in receiver.c in the daemon in rsync 3.1.2, and 3.1.3-development before 2017-12-03, proceeds with certain file metadata updates before checking for a filename in the daemon_filter_list data structure, which allows remote attackers to bypass intended access restrictions. La función recv_files en receiver.c en el demonio en rsync 3.1.2 y 3.1.3-development en versiones anteriores a la 2017-11-03 continúa ciertas actualizaciones de metadatos de archivos antes de buscar un nombre de archivo en la estructura de datos daemon_filter_list.

The daemon in rsync 3.1.2, and 3.1.3-development before 2017-12-03, does not check for fnamecmp filenames in the daemon_filter_list data structure (in the recv_files function in receiver.c) and also does not apply the sanitize_paths protection mechanism to pathnames found in "xname follows" strings (in the read_ndx_and_attrs function in rsync.c), which allows remote attackers to bypass intended access restrictions. El demonio en rsync 3.1.2 y 3.1.3-development en versiones anteriores a la 2017-11-03 no busca nombres de archivo fnamecmp en la estructura de datos daemon_filter_list (en la función recv_files en receiver.c) y tampoco aplica el mecanismo de protección sanitize_paths a los nombres de ruta hallados en cadenas "xname follows" (en la función read_ndx_and_attrs en rsync.c).

The receive_xattr function in xattrs.c in rsync 3.1.2 and 3.1.3-development does not check for a trailing '\0' character in an xattr name, which allows remote attackers to cause a denial of service (heap-based buffer over-read and application crash) or possibly have unspecified other impact by sending crafted data to the daemon. La función receive_xattr en xattrs.c en rsync 3.1.2 y 3.1.3-development no comprueba un carácter final '\0' en un nombre xattr, lo que permite que atacantes remotos provoquen una denegación de servicio (desbordamiento de búfer basado en memoria dinámica o heap y cierre inesperado de la aplicación) o, posiblemente, causen otros impactos no especificados enviando datos manipulados al demonio. • https://bugzilla.samba.org/show_bug.cgi?id=13112 https://git.samba.org/rsync.git/?p=rsync.git%3Ba=commit%3Bh=47a63d90e71d3e19e0e96052bb8c6b9cb140ecc1 https://lists.debian.org/debian-lts-announce/2017/12/msg00020.html https://usn.ubuntu.com/3543-1 https://usn.ubuntu.com/3543-2 https://www.debian.org/security/2017/dsa-4068 • CWE-125: Out-of-bounds Read •
