Description

CVE-2024-41937 affects Apache Airflow versions prior to 2.10.0, introducing a Cross-Site Scripting (XSS) vulnerability. This flaw permits malicious providers to execute JavaScript code within a user's browser when they click on a provider documentation link. The attack vector requires the malicious provider to be installed on the web server and the user to interact with the provider link.

The SVRS score of 61 indicates a moderate vulnerability, necessitating prompt attention and mitigation.

Key Insights

• Cross-Site Scripting (XSS) Vulnerability: The CVE allows malicious actors to inject malicious scripts into the web application, potentially leading to account takeover, data theft, or other harmful actions.
• Impact on Airflow Users: Users interacting with affected Apache Airflow installations are susceptible to this attack.
• Requirement for Provider Installation: The vulnerability necessitates the malicious provider to be installed on the target web server, making it less likely to be exploited in a widespread manner.
• Limited Exploitation Potential: While the vulnerability is real, its exploitable window is narrower due to the specific installation requirement, making it potentially less impactful than other more widespread CVEs.

Mitigation Strategies

1. Upgrade Apache Airflow: Immediately upgrade to Apache Airflow version 2.10.0 or later to patch the vulnerability. This is the most effective way to eliminate the risk.
2. Input Validation: Implement robust input validation and sanitization mechanisms to prevent malicious scripts from entering the application.
3. Content Security Policy (CSP): Employ CSP to restrict the resources allowed to be loaded within the web application, preventing unauthorized script execution.
4. Web Application Firewall (WAF): Utilize a WAF to filter and block malicious traffic, including XSS attacks, at the network level.

Additional Information

While the SVRS score indicates a moderate vulnerability, the requirement for malicious provider installation limits the attack vector. However, prompt mitigation is still recommended.
