Description
This security bulletin contains information about 11 vulnerabilities.
1) Information disclosure (CVE-ID: CVE-2020-1739)
CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
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)
CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
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) Improper Neutralization of Argument Delimiters in a Command (CVE-ID: CVE-2020-1738)
CWE-ID: CWE-88 - Argument Injection or Modification
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:A/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a local user to compromise the target system.
The vulnerability exists when the module package or service is used and the parameter "use" is not specified. If a previous task is executed with a malicious user, the module sent can be selected by the attacker using the ansible facts file.
4) Path traversal (CVE-ID: CVE-2020-1735)
CWE-ID: CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:H/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
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.
5) Incorrect permission assignment for critical resource (CVE-ID: CVE-2020-1736)
CWE-ID: CWE-732 - Incorrect Permission Assignment for Critical Resource
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a local user to gain access to potentially sensitive information.
The vulnerability exists when a file is moved using "atomic_move" primitive as the file mode cannot be specified. A local user can gain unauthorized access to sensitive information on the system.
6) Code Injection (CVE-ID: CVE-2020-10684)
CWE-ID: CWE-94 - Improper Control of Generation of Code ('Code Injection')
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
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.
7) OS Command Injection (CVE-ID: CVE-2019-14904)
CWE-ID: CWE-78 - Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
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.
8) Path traversal (CVE-ID: CVE-2020-1737)
CWE-ID: CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
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.
9) Inclusion of Sensitive Information in Log Files (CVE-ID: CVE-2021-20191)
CWE-ID: CWE-532 - Information Exposure Through Log Files
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
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.
10) Use of insufficiently random values (CVE-ID: CVE-2020-10729)
CWE-ID: CWE-330 - Use of Insufficiently Random Values
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
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.
11) Inclusion of Sensitive Information in Log Files (CVE-ID: CVE-2020-1753)
CWE-ID: CWE-532 - Information Exposure Through Log Files
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
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.
