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 •
