CVSS: 6.5EPSS: 0%CPEs: 4EXPL: 0CVE-2021-4024 – podman: podman machine spawns gvproxy with port bound to all IPs
https://notcve.org/view.php?id=CVE-2021-4024
A flaw was found in podman. The `podman machine` function (used to create and manage Podman virtual machine containing a Podman process) spawns a `gvproxy` process on the host system. The `gvproxy` API is accessible on port 7777 on all IP addresses on the host. If that port is open on the host's firewall, an attacker can potentially use the `gvproxy` API to forward ports on the host to ports in the VM, making private services on the VM accessible to the network. This issue could be also used to interrupt the host's services by forwarding all ports to the VM. • https://bugzilla.redhat.com/show_bug.cgi?id=2026675%2C https://github.com/containers/podman/releases/tag/v3.4.3 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/QFFVJ6S3ZRMPDYB7KYAWEMDHXFZYQPU3 https://access.redhat.com/security/cve/CVE-2021-4024 https://bugzilla.redhat.com/show_bug.cgi?id=2026675 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-346: Origin Validation Error •
CVSS: 7.0EPSS: 0%CPEs: 4EXPL: 0CVE-2021-20188 – podman: container users permissions are not respected in privileged containers
https://notcve.org/view.php?id=CVE-2021-20188
A flaw was found in podman before 1.7.0. File permissions for non-root users running in a privileged container are not correctly checked. This flaw can be abused by a low-privileged user inside the container to access any other file in the container, even if owned by the root user inside the container. It does not allow to directly escape the container, though being a privileged container means that a lot of security features are disabled when running the container. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. • https://bugzilla.redhat.com/show_bug.cgi?id=1915734 https://access.redhat.com/security/cve/CVE-2021-20188 • CWE-863: Incorrect Authorization •
CVSS: 5.9EPSS: 0%CPEs: 1EXPL: 1CVE-2021-20199 – podman: Remote traffic to rootless containers is seen as orginating from localhost
https://notcve.org/view.php?id=CVE-2021-20199
Rootless containers run with Podman, receive all traffic with a source IP address of 127.0.0.1 (including from remote hosts). This impacts containerized applications that trust localhost (127.0.01) connections by default and do not require authentication. This issue affects Podman 1.8.0 onwards. Los contenedores Rootless se ejecutan con Podman, reciben todo el tráfico con una dirección IP de origen 127.0.0.1 (incluyendo desde hosts remotos). Esto afecta a las aplicaciones en contenedores que confían en las conexiones localhost (127.0.01) por defecto y no requieren autenticación. • https://bugzilla.redhat.com/show_bug.cgi?id=1919050 https://github.com/containers/podman/issues/5138 https://github.com/containers/podman/pull/9052 https://github.com/rootless-containers/rootlesskit/pull/206 https://access.redhat.com/security/cve/CVE-2021-20199 • CWE-346: Origin Validation Error •
CVSS: 5.3EPSS: 0%CPEs: 7EXPL: 0CVE-2020-14370 – podman: environment variables leak between containers when started via Varlink or Docker-compatible REST API
https://notcve.org/view.php?id=CVE-2020-14370
An information disclosure vulnerability was found in containers/podman in versions before 2.0.5. When using the deprecated Varlink API or the Docker-compatible REST API, if multiple containers are created in a short duration, the environment variables from the first container will get leaked into subsequent containers. An attacker who has control over the subsequent containers could use this flaw to gain access to sensitive information stored in such variables. Se encontró una vulnerabilidad de divulgación de información en containers/podman en versiones anteriores a 2.0.5. Cuando se usa la API Varlink obsoleta o la API REST compatible con Docker, si son creados varios contenedores en un período corto, las variables de entorno desde el primer contenedor son filtradas hacia los contenedores posteriores. • https://bugzilla.redhat.com/show_bug.cgi?id=1874268 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/G6BPCZX4ASKNONL3MSCK564IVXNYSKLP https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/Y74V7HGQBNLT6XECCSNZNFZIB7G7XSAR https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/Z4Y2FSGQWP4AFT5AZ6UBN6RKHVXUBRFV https://access.redhat.com/security/cve/CVE-2020-14370 • CWE-212: Improper Removal of Sensitive Information Before Storage or Transfer •
