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 •
CVSS: 6.8EPSS: 0%CPEs: 9EXPL: 2CVE-2019-6110 – OpenSSH SCP Client - Write Arbitrary Files
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. SCP clients have an issue where additional files can be copied over without your knowledge. • https://www.exploit-db.com/exploits/46516 https://www.exploit-db.com/exploits/46193 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://security.gentoo.org/glsa/201903-16 https://security.netapp.com/advisory/ntap-20190213-0001 https://sintonen.fi/advisories/scp-client-multiple-vulnerabilities.txt • CWE-838: Inappropriate Encoding for Output Context •

https://notcve.org/view.php?id=CVE-2018-20684
In WinSCP before 5.14 beta, due to missing validation, the scp implementation would accept arbitrary files sent by the server, potentially overwriting unrelated files. This affects TSCPFileSystem::SCPSink in core/ScpFileSystem.cpp. En WinSCP, en versiones anteriores a la 5.14 beta, debido a la falta de validación, la implementación de scp aceptaría archivos arbitrarios enviados por el servidor, lo que podría sobrescribir archivos no relacionados. Esto afecta a TSCPFileSystem::SCPSink en core/ScpFileSystem.cpp. • http://www.securityfocus.com/bid/106526 https://github.com/winscp/winscp/commit/49d876f2c5fc00bcedaa986a7cf6dedd6bf16f54 https://sintonen.fi/advisories/scp-client-multiple-vulnerabilities.txt https://winscp.net/eng/docs/history https://winscp.net/tracker/1675 https://www.oracle.com/security-alerts/cpujan2020.html • CWE-20: Improper Input Validation •
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 •

WinSCP before 5.5.3, when FTP with TLS is used, does not verify that the server hostname matches a domain name in the subject's Common Name (CN) or subjectAltName field of the X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via an arbitrary valid certificate. WinSCP anterior a 5.5.3, cuando FTP con TLS está utilizado, no verifica que el nombre del servidor coincide un nombre de dominio en el nombre común del sujeto (CN) o el campo subjectAltName del certificado X.509, lo que permite a atacantes man-in-the-middle falsificar servidores SSL a través de un certificado valido arbitrario. • http://winscp.net/eng/docs/history http://winscp.net/tracker/show_bug.cgi?id=1152 http://www.securityfocus.com/archive/1/531847/100/0/threaded • CWE-20: Improper Input Validation •
