CVSS: 7.5EPSS: 0%CPEs: 64EXPL: 2CVE-2018-15664 – docker: symlink-exchange race attacks in docker cp
https://notcve.org/view.php?id=CVE-2018-15664
In Docker through 18.06.1-ce-rc2, the API endpoints behind the 'docker cp' command are vulnerable to a symlink-exchange attack with Directory Traversal, giving attackers arbitrary read-write access to the host filesystem with root privileges, because daemon/archive.go does not do archive operations on a frozen filesystem (or from within a chroot). En Docker hasta la versión 18.06.1-ce-rc2, los endpoints API debajo del comando 'docker cp' son vulnerables a un ataque de de tipo symlink-exchange con salto de directorio, dando a los atacantes acceso arbitrario de lectura-escritura al sistema de archivos del host con privilegios de root, porque daemon/archive.go no genera operaciones de archivo en un filesystem congelado (o desde dentro de una operación chroot). A flaw was discovered in the API endpoint behind the 'docker cp' command. The endpoint is vulnerable to a Time Of Check to Time Of Use (TOCTOU) vulnerability in the way it handles symbolic links inside a container. An attacker who has compromised an existing container can cause arbitrary files on the host filesystem to be read/written when an administrator tries to copy a file from/to the container. • http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00066.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00001.html http://www.openwall.com/lists/oss-security/2019/05/28/1 http://www.openwall.com/lists/oss-security/2019/08/21/1 http://www.securityfocus.com/bid/108507 https://access.redhat.com/errata/RHSA-2019:1910 https://access.redhat.com/security/cve/cve-2018-15664 https://bugzilla.suse.com/show_bug.cgi?id=1096726 https://github.com • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition •
CVSS: 9.3EPSS: 0%CPEs: 43EXPL: 22CVE-2019-5736 – Docker Container Escape Via runC Overwrite
https://notcve.org/view.php?id=CVE-2019-5736
runc through 1.0-rc6, as used in Docker before 18.09.2 and other products, allows attackers to overwrite the host runc binary (and consequently obtain host root access) by leveraging the ability to execute a command as root within one of these types of containers: (1) a new container with an attacker-controlled image, or (2) an existing container, to which the attacker previously had write access, that can be attached with docker exec. This occurs because of file-descriptor mishandling, related to /proc/self/exe. runc, hasta la versión 1.0-rc6, tal y como se emplea en Docker, en versiones anteriores a la 18.09.2 y otros productos, permite que los atacantes sobrescriban el binario del host runc (y, así, obtengan acceso root al host) aprovechando la capacidad para ejecutar un comando como root con uno de estos tipos de contenedores: (1) un nuevo contenedor con una imagen controlada por el atacante o (2) un contenedor existente, para el cual el atacante contaba previamente con acceso de escritura, que puede adjuntarse con docker exec. Esto ocurre debido a la gestión incorrecta del descriptor de archivos; esto está relacionado con /proc/self/exe. A flaw was found in the way runc handled system file descriptors when running containers. A malicious container could use this flaw to overwrite contents of the runc binary and consequently run arbitrary commands on the container host system. • https://github.com/Frichetten/CVE-2019-5736-PoC https://www.exploit-db.com/exploits/46369 https://www.exploit-db.com/exploits/46359 https://github.com/twistlock/RunC-CVE-2019-5736 https://github.com/jas502n/CVE-2019-5736 https://github.com/RyanNgWH/CVE-2019-5736-POC https://github.com/zyriuse75/CVE-2019-5736-PoC https://github.com/likescam/CVE-2019-5736 https://github.com/geropl/CVE-2019-5736 https://github.com/si1ent-le/CVE-2019-5736 https://github.com/ • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') CWE-672: Operation on a Resource after Expiration or Release •

Docker before 1.3 does not properly validate image IDs, which allows remote attackers to redirect to another image through the loading of untrusted images via 'docker load'. Docker, en versiones anteriores a la 1.3, no valida correctamente los ID de imagen, lo que permite que atacantes remotos redireccionen a otra imagen mediante la carga de imágenes no fiables utilizando "docker load". • https://bugzilla.redhat.com/show_bug.cgi?id=1168436 https://groups.google.com/forum/#%21msg/docker-announce/aQoVmQlcE0A/smPuBNYf8VwJ • CWE-20: Improper Input Validation •
