CVE-2023-25754
Privilege Context Switching Error vulnerability in apache-airflow (PyPI)
What is CVE-2023-25754 About?
This vulnerability is a Privilege Context Switching Error in Apache Airflow. It affects versions prior to 2.6.0. The impact is a potential bypass of security controls related to privilege separation. Exploitation difficulty is likely moderate, depending on the specific context switching mechanism and how it can be abused.
Affected Software
- apache-airflow
- <2.6.0b1
- <2.6.0
Technical Details
The vulnerability stems from an improper handling of privilege context switching within Apache Airflow. This means that when a process or a thread attempts to transition from one privilege level to another, or from one user context to another, the mechanism responsible for this transition fails to properly isolate or switch the context. This could result in operations being executed with unintended or elevated privileges, or in the context of a different user than intended, leading to unauthorized actions or access.
What is the Impact of CVE-2023-25754?
Successful exploitation may allow attackers to perform actions with elevated privileges, bypass access controls, or operate under an unauthorized user context, leading to unauthorized data access, modification, or system compromise.
What is the Exploitability of CVE-2023-25754?
Exploitation typically requires an attacker to interact with the Airflow system, either through an authenticated session or by leveraging another vulnerability that grants initial access. The complexity could be moderate to high, as it depends on understanding the specific internal mechanisms of privilege context switching in Airflow. Authentication might be required to initiate the flawed context switch, or the vulnerability could be triggered post-authentication. This could be a local or remote attack depending on how the context switch can be initiated. Specific configurations or custom DAGs might increase the attack surface.
