Short explanation
In apache-airflow-providers-ssh before 7.0.1, SSHRemoteJobOperator quotes environment parameter values only once, allowing shell commands to be executed on the remote SSH host. S0, S1
Users who can trigger a DAG but cannot author DAGs can run arbitrary commands on the remote host as the SSH connection user. S0, S1
What should be done?
- Upgrade apache-airflow-providers-ssh to version 7.0.1 or later
- Follow vendor advisory guidance
Chain of evidence and sources
apache-airflow-providers-ssh 7.0.1 öncesi sürümlerde environment parametre değerleri eksik tırnaklama nedeniyle uzak sunucuda kabuk komutu olarak çalıştırılabilmektedir.
Etkilenen sürümler 4.3.0 ile 7.0.1 arasındadır ve kullanıcıların 7.0.1 veya sonraki sürüme yükseltmesi önerilmektedir.
Show the technical text from the sources
In apache-airflow-providers-ssh before 7.0.1, SSHRemoteJobOperator quoted the values of its templated `environment` parameter only once, although they are placed inside an already-quoted wrapper script, so shell syntax such as `$(...)` in a value was executed on the remote SSH host. In a Dag that passes trigger-time input such as `params` or `dag_run.conf` into `environment`, a user who can trigger that Dag but cannot author Dags could run arbitrary commands on the remote host as the SSH connection's user. Users are advised to upgrade apache-airflow-providers-ssh to 7.0.1 or later.
