CVE-2022-23596
Use of Web Browser Cache Containing Sensitive Information vulnerability in junrar (Maven)
What is CVE-2022-23596 About?
This vulnerability, categorized as 'Use of Web Browser Cache Containing Sensitive Information', affects Apache Airflow when sensitive data might be stored in the local browser cache. It stems from the application not returning appropriate 'Cache-Control' headers for dynamic content. Successful exploitation could lead to unintended exposure of sensitive information to unauthorized individuals with access to the browser's cache, but requires local access to the compromised machine.
Affected Software
Technical Details
Apache Airflow versions prior to 2.9.2 are vulnerable because they fail to set proper 'Cache-Control' headers for dynamic content. Web browsers, by default, may cache resources to improve performance. Without explicit 'Cache-Control' headers (e.g., 'no-store', 'no-cache'), browsers might store dynamic content, which could include sensitive information or session data, locally on the user's machine. This means that if an attacker gains local access to a user's browser cache, they could retrieve sensitive data that was previously displayed by Airflow. The vulnerability is a client-side issue related to browser behavior and interaction with HTTP headers.
What is the Impact of CVE-2022-23596?
Successful exploitation may allow attackers to access sensitive information previously displayed in the application, leading to data exposure, privacy breaches, and potential unauthorized access if session tokens are cached.
What is the Exploitability of CVE-2022-23596?
Exploitation of this vulnerability primarily requires local access to a user's machine where sensitive information was cached by the web browser, or access to the physical device. It is a client-side vulnerability, meaning an attacker compromises the browser's cache rather than directly attacking the Airflow server through remote means. No specific authentication is required at the time of cache access, assuming the attacker has already gained control of the local machine. The complexity is low once local access is achieved. The likelihood of exploitation increases if users access Airflow from shared or publicly accessible computers, or if their devices are susceptible to malware that can exfiltrate browser cache data.
