Description
This security bulletin contains information about 9 secuirty vulnerabilities.
1) Information disclosure (CVE-ID: CVE-2020-1739)
The vulnerability allows a local user to gain access to potentially sensitive information.
The vulnerability exists due to password being exposed to local users when a password is set with the argument "password" of svn module. A local user can read the cmdline file from that particular PID on the procfs and obtain the password.
2) Information disclosure (CVE-ID: CVE-2020-1740)
The vulnerability allows a local user to gain access to potentially sensitive information.
The vulnerability exists due to excessive data output by the application when using Ansible Vault for editing encrypted files. A local user can gain unauthorized access to sensitive information on the system.
3) Path traversal (CVE-ID: CVE-2020-1735)
The vulnerability allows a local user to perform directory traversal attacks.
The vulnerability exists due to input validation error when processing directory traversal sequences. A local administrator can intercept the module, inject a new path, and then choose a new destination path on the controller node.
4) Code Injection (CVE-ID: CVE-2020-10684)
The vulnerability allows a local user to execute arbitrary code on the target system.
The vulnerability exists due to improper input validation when using "ansible_facts" as a subkey of itself and promoting it to a variable when inject is enabled, overwriting the "ansible_facts" after the clean. A local user can alter the "ansible_facts", such as "ansible_hosts", "users" and any other key data which would lead into privilege escalation or code injection
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
5) OS Command Injection (CVE-ID: CVE-2019-14904)
The vulnerability allows a remote user to execute arbitrary shell commands on the target system.
The vulnerability exists due to improper input validation when processing zone names within the solaris_zone module. A remote uuser can provide a specially crafted zone name as a parameter to the os.system() call and execute arbitrary OS commands on the target system.
6) Path traversal (CVE-ID: CVE-2020-1737)
The vulnerability allows a local user to perform directory traversal attacks.
The vulnerability exists due to input validation error when processing directory traversal sequences within the "Extract-Zip" function from the "win_unzip" module. A local user can send a specially crafted HTTP request and read arbitrary files on the system.
7) Inclusion of Sensitive Information in Log Files (CVE-ID: CVE-2021-20191)
The vulnerability allows a local user to gain access to sensitive information.
The vulnerability exists due to software stores sensitive information into log files. A local user can read the log files and gain access to sensitive data.
8) Use of insufficiently random values (CVE-ID: CVE-2020-10729)
The vulnerability allows a local user to gain access to sensitive information.
The vulnerability exists due to usegae of insufficiently random values in Ansible. Two random password lookups of the same length generate the equal value as the template caching action for the same file since no re-evaluation happens.
9) Inclusion of Sensitive Information in Log Files (CVE-ID: CVE-2020-1753)
The vulnerability allows a local user to gain access to sensitive information.
The vulnerability exists due to software stores sensitive information into log files when managing Kubernetes using the k8s connection plugin. A local user can read the log files and gain access to sensitive data.
