Enterprise Business Application Security Development Issues

Objective

This document will describe different areas of program vulnerabilities that can be found in the source code of Enterprise Business applications and ERP systems.

Purpose

The purpose of this document is to increase awareness of the developers of Enterprise Business software. Here, we will collect top software vulnerabilities in server side and frontend side that can exist in Business Applications.

Intro

There are many different languages and technologies that can be used to develop business applications and write custom code such as ABAP for SAP, PeopleCode for PeopleSoft, X++ for Microsoft Dynamics, PL/SQL for Oracle EBS, LotusScript for Lotus and much, much more. Here, we will try to categorize them into 9 main areas filtered by criticality.

Main

Crosslinks to CWE, SANS, OWASP and risks with descriptions will be added soon.

9 most critical types of issues in source code (EASAD-9-2013)

1 Injections (code, SQL, OS)
2 Critical calls (to DB, to OS)
3 Missing or bad access control checks (missing auth checks)
4 Directory / path traversal (write, read, SMBRelay)
5 Modification of displayed content (XSS stored, XSS linked, JS/HTML injections)
6 Backdoors (hardcoded credentials)
7 Covert channels (sockets, HTTP calls, SSRFs)
8 Information disclosure (hardcoded users, passwords, debug information)
9 Obsolete statements (READ TABLE, kernel methods)
