CVSS: 7.8EPSS: 0%CPEs: 14EXPL: 0CVE-2019-10166 – libvirt: virDomainManagedSaveDefineXML API exposed to readonly clients
https://notcve.org/view.php?id=CVE-2019-10166
It was discovered that libvirtd, versions 4.x.x before 4.10.1 and 5.x.x before 5.4.1, would permit readonly clients to use the virDomainManagedSaveDefineXML() API, which would permit them to modify managed save state files. If a managed save had already been created by a privileged user, a local attacker could modify this file such that libvirtd would execute an arbitrary program when the domain was resumed. Se detectó que libvirtd, versiones 4.x.x anteriores a 4.10.1 y versiones 5.x.x anteriores a 5.4.1, permitiría a los clientes de solo lectura utilizar la API de la función virDomainManagedSaveDefineXML(), lo que les permitiría modificar archivos de estado managed save. Si un managed save ya ha sido creado por un usuario privilegiado, un atacante local podría modificar este archivo de manera que libvirtd ejecutaría un programa arbitrario cuando el dominio esté reanudado. It was discovered that libvirtd would permit readonly clients to use the virDomainManagedSaveDefineXML() API, which would permit them to modify managed save state files. • https://access.redhat.com/libvirt-privesc-vulnerabilities https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-10166 https://security.gentoo.org/glsa/202003-18 https://access.redhat.com/security/cve/CVE-2019-10166 https://bugzilla.redhat.com/show_bug.cgi?id=1720114 • CWE-284: Improper Access Control •
CVSS: 8.8EPSS: 0%CPEs: 14EXPL: 0CVE-2019-10167 – libvirt: arbitrary command execution via virConnectGetDomainCapabilities API
https://notcve.org/view.php?id=CVE-2019-10167
The virConnectGetDomainCapabilities() libvirt API, versions 4.x.x before 4.10.1 and 5.x.x before 5.4.1, accepts an "emulatorbin" argument to specify the program providing emulation for a domain. Since v1.2.19, libvirt will execute that program to probe the domain's capabilities. Read-only clients could specify an arbitrary path for this argument, causing libvirtd to execute a crafted executable with its own privileges. La API libvirt de la función virConnectGetDomainCapabilities(), versiones 4.x.x anteriores a 4.10.1 y versiones 5.x.x anteriores a 5.4.1, acepta un argumento "emulatorbin" para especificar el programa que proporciona emulación para un dominio. Desde versión v1.2.19, libvirt ejecutará ese programa para examinar las capacidades del dominio. • https://access.redhat.com/libvirt-privesc-vulnerabilities https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-10167 https://security.gentoo.org/glsa/202003-18 https://access.redhat.com/security/cve/CVE-2019-10167 https://bugzilla.redhat.com/show_bug.cgi?id=1720117 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') CWE-250: Execution with Unnecessary Privileges CWE-284: Improper Access Control CWE-862: Missing Authorization •

CVSS: 9.8EPSS: 0%CPEs: 28EXPL: 0CVE-2019-10160 – python: regression of CVE-2019-9636 due to functional fix to allow port numbers in netloc
https://notcve.org/view.php?id=CVE-2019-10160
A security regression of CVE-2019-9636 was discovered in python since commit d537ab0ff9767ef024f26246899728f0116b1ec3 affecting versions 2.7, 3.5, 3.6, 3.7 and from v3.8.0a4 through v3.8.0b1, which still allows an attacker to exploit CVE-2019-9636 by abusing the user and password parts of a URL. When an application parses user-supplied URLs to store cookies, authentication credentials, or other kind of information, it is possible for an attacker to provide specially crafted URLs to make the application locate host-related information (e.g. cookies, authentication data) and send them to a different host than where it should, unlike if the URLs had been correctly parsed. The result of an attack may vary based on the application. Se descubrió una regresión de seguridad de CVE-2019-9636 en python desde commit con ID d537ab0ff9767ef024f26246899728f0116b1ec3 que afecta a las versiones 2.7, 3.5, 3.6, 3.7 y de v3.8.0a4 a v3.8.0b1, el cual permite a un atacante explotar CVE-2019-9636 violando las partes usuario (user) y contraseña (password) de una URL. Cuando una aplicación analiza las URL proporcionadas por el usuario para almacenar cookies, credenciales de autenticación u otro tipo de información, es posible que un atacante proporcione URL especialmente creadas para que la aplicación ubique información relacionada con el host (por ejemplo, cookies, datos de autenticación) y envíe a un host diferente al que debería, a diferencia de si las URL se analizaron correctamente. • http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00042.html http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00040.html https://access.redhat.com/errata/RHSA-2019:1587 https://access.redhat.com/errata/RHSA-2019:1700 https://access.redhat.com/errata/RHSA-2019:2437 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-10160 https://github.com/python/cpython/commit/250b62acc59921d399f0db47db3b462cd6037e09 https://github.com/python/cpython/commit/8d0ef0b5edeae52960c7ed05ae8a12388324f87e • CWE-172: Encoding Error CWE-522: Insufficiently Protected Credentials •
