Produktbeschreibung: Ansible ist eine Software zur Automatisierung von Cloud Provisionierung, zum Konfigurationsmanagement und zur Anwendungsbereitstellung.
Angriff: Ein lokaler Angreifer kann eine Schwachstelle in Ansible und Ansible Tower ausnutzen, um Sicherheitsvorkehrungen zu umgehen.
Betroffene Betriebssysteme: - Linux - MacOS X - UNIX
CVE-2020-14365

Es existiert eine Schwachstelle in der Ansible Engine und Ansible Tower. Sie beruht darauf, dass GPG Signaturen nicht beachtet werden, wenn Pakete mit dem "dnf" Modul installiert werden und "disable_gpg_check" auf "FALSE" gesetzt ist (Standardeinstellung). Ein Angreifer kann dieses nutzen und Sicherheitsmechanismen umgehen und so beliebige Pakete installieren.
