CVE-2022-38170— Overly permissive umask for daemons

Quick assessment

Affected
Apache Software Foundation Apache Airflow
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Apache Airflow是美国阿帕奇（Apache）基金会的一套用于创建、管理和监控工作流程的开源平台。该平台具有可扩展和动态监控等特点。 Apache Airflow 2.3.4之前的版本存在安全漏洞，该漏洞源于当运行时带有“--daemon”标志时，会为多个Airflow组件配置一个不安全的权限，这可能会导致在Airflow主目录下给具有全局可写权限的文件带来竞争条件，并允许本地用户通过web服务器公开任意文件内容。
