You can download the package to create the reverse shell here. Please, note that before using it you should **decompress it, change the `setup.py`, and put your IP for the reverse shell**:

{% file src="../../../.gitbook/assets/reverse.tar.gz" %}

This package is called `Reverse`. However, it was specially crafted so that when you exit the reverse shell the rest of the installation will fail, so you **won't leave any extra python package installed on the server** when you leave.

## Bypassing protections through encodings (UTF-7)
|
||||
|
||||
In [**this writeup**](https://blog.arkark.dev/2022/11/18/seccon-en/#misc-latexipy) UFT-7 is used to load and execute arbitrary python code inside an apparent sandbox:
|
||||
|
||||
```python
|
||||
assert b"+AAo-".decode("utf_7") == "\n"
|
||||
|
||||
payload = """
|
||||
# -*- coding: utf_7 -*-
|
||||
def f(x):
|
||||
return x
|
||||
#+AAo-print(open("/flag.txt").read())
|
||||
""".lstrip()
|
||||
```
|
||||
|
||||
It is also possible to bypass it using other encodings, e.g. `raw_unicode_escape` and `unicode_escape`.
|
||||
|
||||
## Python execution without calls
|
||||
|
||||
If you are inside a python jail that **doesn't allow you to make calls**, there are still some ways to **execute arbitrary functions, code** and **commands**.

Technique taken [**from this writeup**](https://blog.arkark.dev/2022/11/18/seccon-en/#web-spanote)**.**
|
||||
|
||||
There are two important types of cache:
|
||||
|
||||
* **back/forward cache (bfcache)**
|
||||
* ref. [https://web.dev/i18n/en/bfcache/](https://web.dev/i18n/en/bfcache/)
|
||||
* It stores a complete snapshot of a page **including the JavaScript heap**.
|
||||
* The cache is used for back/forward navigations.
|
||||
* it has preference over disk cache
|
||||
* **disk cache**
|
||||
* ref. [https://www.chromium.org/developers/design-documents/network-stack/disk-cache/](https://www.chromium.org/developers/design-documents/network-stack/disk-cache/)
|
||||
* It stores a resource fetched from the web. The cache **doesn't include the JavaScript heap**.
|
||||
* The cache is also used for back/forward navigations to skip communication costs.
|
||||
|
||||
As a interesting point of disk cache, the **cache includes** not only the HTTP response rendered to a web page, but also **those fetched with `fetch`**. In other words, if you a**ccess the URL for a fetched** resource, the **browser will render the resource** on the page.
|
||||
|
||||
There is another important point. If both disk cache and bfcache are valid for an accessed page at back/forward navigations, the **bfcache has priority over the disk cache**. So, if you need to access a page stored in both caches but you want to use the one from the disk, you need to somehow **disable bfcache.**
|
||||
|
||||
### Disable bfcache
|
||||
|
||||
|
||||
|
||||
bfcache is disabled by [default options](https://github.com/puppeteer/puppeteer/blob/v19.2.0/packages/puppeteer-core/src/node/ChromeLauncher.ts#L175) of puppeteer.
