CVE-2020-1739

Se detectó un fallo en Ansible versiones 2.7.16 y anteriores, versiones 2.8.8 y anteriores y versiones 2.9.5 y anteriores, cuando es establecida una contraseña con el argumento "password" del módulo svn, es usado en la línea de comandos svn, revelando a otros usuarios dentro del mismo nodo. Un atacante podría tomar ventaja de ello mediante una lectura del archivo cmdline de ese PID en particular en los procfs.

A flaw was found in Ansible Engine. When a password is set with the argument "password" of svn module, it is used on svn command line, disclosing to other users within the same node. An attacker could take advantage by reading the cmdline file from that particular PID on the procfs.

It was discovered that Ansible did not properly verify certain fields of X.509 certificates. An attacker could possibly use this issue to spoof SSL servers if they were able to intercept network communications. This issue only affected Ubuntu 14.04 LTS. Martin Carpenter discovered that certain connection plugins for Ansible did not properly restrict users. An attacker with local access could possibly use this issue to escape a restricted environment via symbolic links misuse. This issue only affected Ubuntu 14.04 LTS.
