critical Nessus Plugin ID 127043
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote Ubuntu host is missing a security-related patch.

Description

It was discovered that Ansible failed to properly handle sensitive information. A local attacker could use those vulnerabilities to extract them. (CVE-2017-7481) (CVE-2018-10855) (CVE-2018-16837) (CVE-2018-16876) (CVE-2019-10156)

It was discovered that Ansible could load configuration files from the current working directory containing crafted commands. An attacker could run arbitrary code as result. (CVE-2018-10874) (CVE-2018-10875)

It was discovered that Ansible fetch module had a path traversal vulnerability. A local attacker could copy and overwrite files outside of the specified destination. (CVE-2019-3828).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected ansible package.
