CVSS: 6.8EPSS: 0%CPEs: 51EXPL: 0CVE-2019-6109 – openssh: Missing character encoding in progress display allows for spoofing of scp client output
https://notcve.org/view.php?id=CVE-2019-6109
An issue was discovered in OpenSSH 7.9. Due to missing character encoding in the progress display, a malicious server (or Man-in-The-Middle attacker) can employ crafted object names to manipulate the client output, e.g., by using ANSI control codes to hide additional files being transferred. This affects refresh_progress_meter() in progressmeter.c. Se ha descubierto un problema en OpenSSH 7.9. Debido a la falta de cifrado de caracteres en la pantalla de progreso, un servidor malicioso (o atacante Man-in-the-Middle) puede emplear nombres de objeto manipulados para manipular la salida del cliente, por ejemplo, empleando códigos de control de ANSI para ocultar los archivos adicionales que se están transfiriendo. • http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00058.html https://access.redhat.com/errata/RHSA-2019:3702 https://cert-portal.siemens.com/productcert/pdf/ssa-412672.pdf https://cvsweb.openbsd.org/src/usr.bin/ssh/progressmeter.c https://cvsweb.openbsd.org/src/usr.bin/ssh/scp.c https://lists.debian.org/debian-lts-announce/2019/03/msg00030.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/W3YVQ2BPTOVDCFDVNC2GGF5P5ISFG37G https:// • CWE-116: Improper Encoding or Escaping of Output CWE-451: User Interface (UI) Misrepresentation of Critical Information •

https://notcve.org/view.php?id=CVE-2019-6110
In OpenSSH 7.9, due to accepting and displaying arbitrary stderr output from the server, a malicious server (or Man-in-The-Middle attacker) can manipulate the client output, for example to use ANSI control codes to hide additional files being transferred. En OpenSSH 7.9, debido a la aceptación y la nuestra de salidas stderr arbitrarias del servidor, un servidor malicioso (o atacante Man-in-the-Middle) puede manipular la salida del cliente, por ejemplo, para emplear códigos de control de ANSI para ocultar los archivos adicionales que se están transfiriendo.

CVSS: 5.3EPSS: 0%CPEs: 56EXPL: 0CVE-2018-20685 – openssh: scp client improper directory name validation
https://notcve.org/view.php?id=CVE-2018-20685
In OpenSSH 7.9, scp.c in the scp client allows remote SSH servers to bypass intended access restrictions via the filename of . or an empty filename. The impact is modifying the permissions of the target directory on the client side. En OpenSSH 7.9, scp.c en el cliente scp permite que los servidores SSH omitan las restricciones de acceso planeadas mediante un nombre de archivo "." o un nombre de archivo vacío. El impacto consiste en modificar los permisos del directorio objetivo en el lado del cliente. • http://www.securityfocus.com/bid/106531 https://access.redhat.com/errata/RHSA-2019:3702 https://cert-portal.siemens.com/productcert/pdf/ssa-412672.pdf https://cvsweb.openbsd.org/cgi-bin/cvsweb/src/usr.bin/ssh/scp.c.diff?r1=1.197&r2=1.198&f=h https://github.com/openssh/openssh-portable/commit/6010c0303a422a9c5fa8860c061bf7105eb7f8b2 https://lists.debian.org/debian-lts-announce/2019/03/msg00030.html https://security.gentoo.org/glsa/201903-16 https://security.gentoo.org/glsa/202007- • CWE-20: Improper Input Validation CWE-863: Incorrect Authorization •

Remotely observable behaviour in auth-gss2.c in OpenSSH through 7.8 could be used by remote attackers to detect existence of users on a target system when GSS2 is in use. NOTE: the discoverer states 'We understand that the OpenSSH developers do not want to treat such a username enumeration (or "oracle") as a vulnerability.' Un comportamiento observable de forma remota en auth-gss2.c en OpenSSH hasta la versión 7.8 podría ser empleado por atacantes remotos para detectar la existencia de usuarios en un sistema objetivo cuando se está empleando GSS2. NOTA: el descubridor indica que "entendemos que los desarrolladores de OpenSSH no quieran tratar tal listado de nombres de usuario (u "oráculo") como una vulnerabilidad". • http://seclists.org/oss-sec/2018/q3/180 http://www.securityfocus.com/bid/105163 https://security.netapp.com/advisory/ntap-20181221-0001 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
