BIT-airflow-2023-22888
Service Disruption vulnerability in apache-airflow (PyPI)
What is BIT-airflow-2023-22888 About?
This vulnerability in Apache Airflow, affecting versions prior to 2.6.3, allows an authenticated attacker to cause a service disruption. By manipulating the 'run_id' parameter, an attacker can interfere with the normal operation of the service, leading to denial of service. Exploitation requires prior authentication, making its exploitability moderately complex.
Affected Software
Technical Details
Apache Airflow versions before 2.6.3 contain a flaw where the 'run_id' parameter, likely used to identify and manage workflow runs, is not adequately sanitized or validated. An authenticated attacker can submit a specially crafted 'run_id' value, possibly one that is excessively long, contains malicious characters, or triggers an unexpected state in the Airflow scheduler or worker. This manipulation can lead to resource exhaustion, errors, or crashes within the Airflow environment, effectively disrupting the service. The vulnerability relies on the attacker having legitimate access to the Airflow application.
What is the Impact of BIT-airflow-2023-22888?
Successful exploitation may allow attackers to cause a denial of service, rendering the affected service unavailable to legitimate users. This can lead to operational outages, data processing delays, and an overall degradation of system reliability, potentially affecting dependent applications and business operations.
What is the Exploitability of BIT-airflow-2023-22888?
Exploitation necessitates an authenticated user, elevating the complexity slightly as an attacker must first gain access to valid credentials. The attack is remote and specifically targets the 'run_id' parameter. There are no special conditions beyond authentication, but the attacker needs to understand how this parameter is processed to craft an effective payload. The risk factors for exploitation include weak authentication mechanisms or compromised user accounts that provide the necessary access.
