In Apache Airflow versions prior to 2.4.2, there was an open redirect in the webserver's `/confirm` endpoint. This vulnerability allows attackers to redirect users to malicious sites, potentially leading to phishing attacks or the exposure of sensitive information. The severity of this vulnerability is classified as medium, with a CVSS score of 6.1. Organizations using affected versions are at risk, particularly if they expose the application to untrusted users.
Risk to organizations includes unauthorized redirection of users to harmful sites. Given the nature of this vulnerability, the urgency for defenders to address it is high. Organizations should prioritize patching immediately.
As of now, there is no known public exploit or proof of concept for this vulnerability, reducing immediate concerns about exploitation in the wild. However, this does not negate the importance of remediation.
Organizations should ensure they are running the latest version of Apache Airflow to mitigate this risk. Regular updates and security audits are essential to maintaining a secure environment.
Vulnerability Details
The Apache Airflow vulnerability CVE-2022-43985 is characterized by an open redirect in the webserver’s `/confirm` endpoint. This issue is classified under CWE-601, indicating a weakness related to URL redirection. The CVSS score of 6.1 signifies a medium level of risk, highlighting the importance of user interaction and a low complexity for exploitation.
The vulnerability affects all versions of Apache Airflow prior to 2.4.2, with the issue being published on November 2, 2022. Given the scope of the vulnerability, it can have a significant impact on confidentiality and integrity, albeit with no availability impact.
Technical Analysis
The root cause of this vulnerability lies in the improper handling of user input within the `/confirm` endpoint. Attackers may leverage this weakness by manipulating the redirect URL, leading users to unintended destinations. The attack vector is network-based, requiring user interaction to execute successfully.
Despite the low complexity of the attack, it requires no privileges to exploit, making it accessible to a wider range of attackers. The confidentiality and integrity impacts are classified as low, while availability is unaffected.
Risk & Impact Analysis
Real-world deployment of this vulnerability poses a risk of unauthorized access and manipulation of users’ navigation paths. Attackers can exploit this weakness to redirect users to phishing sites, potentially leading to credential theft or malware installation. Consequently, organizations using Apache Airflow should assess their exposure and implement necessary mitigations.
The urgency assessment based on the CVSS score indicates that organizations should address this issue in their priority patch cycle. Regular vulnerability assessments and monitoring for signs of exploitation are recommended to gauge the potential impact.
