CVE-2022-3697
Information Disclosure vulnerability in ansible (PyPI)
What is CVE-2022-3697 About?
This vulnerability is an Information Disclosure flaw in Ansible's `amazon.aws` collection when using the `tower_callback` parameter with the `amazon.aws.ec2_instance` module. An attacker can leverage this insecure handling to leak sensitive information, specifically passwords, into logs. Exploitation is simple if the vulnerable configuration is in use.
Affected Software
Technical Details
The vulnerability resides in the amazon.aws collection within Ansible, specifically when the tower_callback parameter is used with the amazon.aws.ec2_instance module. The module insecurely handles this parameter, leading to sensitive information, such as passwords, being inadvertently written into logs. This occurs because the data passed to or processed via the tower_callback mechanism is not properly sanitized or redacted before being recorded, exposing credentials in plaintext within system logs. The attack vector is the review of these logs by an unauthorized individual.
What is the Impact of CVE-2022-3697?
Successful exploitation may allow attackers to gain unauthorized access to sensitive information, specifically passwords, leading to further system compromise or unauthorized access to AWS resources.
What is the Exploitability of CVE-2022-3697?
Exploitation complexity is low once the vulnerable configuration is identified. An attacker primarily needs access to the logs generated by an Ansible system configured with the amazon.aws.ec2_instance module using tower_callback. Authentication to the Ansible system or the log server is typically required, making it a local or authenticated remote exploitation scenario. Privilege requirements would involve having read access to the relevant log files. The primary risk factor is the collection of logs in an accessible location for unauthorized users, coupled with the use of the vulnerable parameter.
