Denial of Service (DoS) Affecting apache-airflow package, versions [,2.7.0)

apache-airflow is a platform to programmatically author, schedule, and monitor workflows.

Affected versions of this package are vulnerable to Denial of Service (DoS) that can be exploited by an authenticated user with Connection edit privileges. This vulnerability allows the user to access connection information and exploit the test connection feature by sending many requests, leading to a denial of service (DoS) condition on the server.

Note:

Malicious actors can leverage this vulnerability to establish harmful connections with the server.

Mitigation:

Administrators are encouraged to review and adjust user permissions to restrict access to sensitive functionalities, reducing the attack surface.

Denial of Service (DoS) describes a family of attacks, all aimed at making a system inaccessible to its intended and legitimate users.

Unlike other vulnerabilities, DoS attacks usually do not aim at breaching security. Rather, they are focused on making websites and services unavailable to genuine users resulting in downtime.

One popular Denial of Service vulnerability is DDoS (a Distributed Denial of Service), an attack that attempts to clog network pipes to the system by generating a large volume of traffic from many machines.

When it comes to open source libraries, DoS vulnerabilities allow attackers to trigger such a crash or crippling of the service by using a flaw either in the application code or from the use of open source libraries.

Two common types of DoS vulnerabilities:

• High CPU/Memory Consumption- An attacker sending crafted requests that could cause the system to take a disproportionate amount of time to process. For example, commons-fileupload:commons-fileupload.

• Crash - An attacker sending crafted requests that could cause the system to crash. For Example, npm ws package
