Description

This security bulletin contains information about 3 vulnerabilities.


1) Information disclosure (CVE-ID: CVE-2018-10855)

CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote attacker to obtain potentially sensitive information on the target system.
The weakness exists due to improper honor of the no_log task flag for failed tasks. When the no_log flag has been used to protect sensitive data passed to a task from being logged, and that task does not run successfully, Ansible will expose sensitive data in log files and on the terminal of the user running Ansible.

2) Privilege escalation (CVE-ID: CVE-2018-10874)

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H/E:U/U:Clear


The vulnerability allows a local attacker to gain elevated privileges on the target system.

The vulnerability exists due to the system reads the 'ansible.cfg' file from the current working directory when running an ad-hoc command. A local attacker can modify the file to reference arbitrary plugin or module paths and execute arbitrary code from those paths with elevated privileges.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


3) Privilege escalation (CVE-ID: CVE-2018-10875)

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H/E:U/U:Clear


The vulnerability allows a local attacker to gain elevated privileges on the target system.

The vulnerability exists due to the system loads inventory variables from the current working directory when running an ad-hoc command. A local attacker can modify the variables and execute arbitrary code from those paths with elevated privileges.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
