CVE-2022-40604
information extraction vulnerability in apache-airflow (PyPI)
What is CVE-2022-40604 About?
This vulnerability in Apache Airflow versions 2.3.0 through 2.3.4 involves unnecessary URL formatting that can be abused for information extraction. An attacker can craft a URL to reveal sensitive system details, making it moderately easy to exploit. The impact is the leakage of potentially useful information for further attacks.
Affected Software
- apache-airflow
- >=2.3.0, <2.4.0rc1
- >=2.3.0, <2.4.0b1
Technical Details
The vulnerability in Apache Airflow results from an oversight in how parts of a URL were processed and formatted. Specifically, certain components of incoming URLs were unnecessarily reformatted or processed in a way that could lead to the unintended disclosure of information. An attacker could craft a specially malformed or otherwise unusual URL that, when handled by the vulnerable Airflow instance, would cause internal system details or other sensitive information related to the application's environment or configuration to be exposed in error messages, logs, or responses. This information, while not directly providing full system access, could be crucial for an attacker to understand the system's architecture, installed versions (e.g., Python, Airflow), or node names, facilitating more targeted attacks later.
What is the Impact of CVE-2022-40604?
Successful exploitation may allow attackers to gain insights into the system's configuration and environment, aiding in the reconnaissance phase for more sophisticated attacks, and compromising data confidentiality.
What is the Exploitability of CVE-2022-40604?
Exploitation involves crafting specific URLs and sending them to the Apache Airflow instance. No authentication is explicitly mentioned as required, suggesting it could be an unauthenticated remote attack. The complexity is low to moderate, assuming knowledge of how Airflow processes URLs. The prerequisites include access to send web requests to the Airflow instance. The primary risk factor is the potential exposure of data that could significantly assist an attacker in probing for other vulnerabilities or understanding the system's defenses.
