# Introduction about SAP

SAP stands for Systems Applications and Products in Data Processing. SAP, by definition, is also the name of the ERP (Enterprise Resource Planning) software as well as the name of the company.
SAP system consists of a number of fully integrated modules, which covers virtually every aspect of business management.

Each SAP instance (or SID) is composed of three layers: database, application and presentation), each landscape usually consists of four instances: dev, test, QA and production.
Each of the layers can be exploited to some extent, but most effect can be gained by attacking the database.

Each SAP instance is divided into clients. Each one has a user SAP*, the application’s equivalent of “root”.
Upon initial creation, this user SAP* gets a default password: “060719992” (more default password below).
You’d be surprised if you knew how often these passwords aren’t changed in test or dev environments!

Try to get access to the shell of any server using username <SID>adm.
Bruteforcing can help, whoever there can be Account Lockout mechanism.

# Discovery

- Check the Application Scope or Program Brief for testing. Take note of the hostnames or system instances for connecting to SAP GUI.
- Use OSINT (open source intelligence), Shodan and Google Dorks to check for files, subdomains, and juicy information if the application is Internet-facing or public:

    inurl:50000/irj/portal
    inurl:IciEventService/IciEventConf
    inurl:/wsnavigator/jsps/test.jsp
    inurl:/irj/go/km/docs/
    https://www.shodan.io/search?query=sap+portal
    https://www.shodan.io/search?query=SAP+Netweaver
    https://www.shodan.io/search?query=SAP+J2EE+Engine

- Here is what http://SAP:50000/irj/portal looks like

- Use nmap to check for open ports and known services (sap routers, webdnypro, web services, web servers, etc.)

- Crawl the URLs if there is a web server running.

- Fuzz the directories (you can use Burp Intruder) if it has web servers on certain ports. Here are some good wordlists provided by the SecLists Project for finding default SAP ICM Paths and other interesting directories or files:

  https://github.com/danielmiessler/SecLists/blob/master/Discovery/Web-Content/URLs/urls_SAP.txt
  https://github.com/danielmiessler/SecLists/blob/master/Discovery/Web-Content/CMS/SAP.fuzz.txt
  https://github.com/danielmiessler/SecLists/blob/master/Discovery/Web-Content/sap.txt

- Use the SAP SERVICE DISCOVERY auxiliary Metasploit module for enumerating SAP instances/services/components:

    msf > use auxiliary/scanner/sap/sap_service_discovery
    msf auxiliary(sap_service_discovery) > show options
    Module options (auxiliary/scanner/sap/sap_service_discovery):
       Name         Current Setting  Required  Description
       ----         ---------------  --------  -----------
       CONCURRENCY  10               yes       The number of concurrent ports to check per host
       INSTANCES    00-01            yes       Instance numbers to scan (e.g. 00-05,00-99)
       RHOSTS                        yes       The target address range or CIDR identifier
       THREADS      1                yes       The number of concurrent threads
       TIMEOUT      1000             yes       The socket connect timeout in milliseconds
    msf auxiliary(sap_service_discovery) > set rhosts 192.168.96.101
    rhosts => 192.168.96.101
    msf auxiliary(sap_service_discovery) > run
    [*] 192.168.96.101:       - [SAP] Beginning service Discovery '192.168.96.101'

## Testing the Thick Client / SAP GUI

Here is the command to connect to SAP GUI
`sapgui <sap server hostname> <system number>`

- Check for default credentials (In Bugcrowd’s Vulnerability Rating Taxonomy, this is considered as P1 -> Server Security Misconfiguration | Using Default Credentials | Production Server):

- Run Wireshark then authenticate to the client (SAP GUI) using the credentials you got because some clients transmit credentials without SSL. There are two known plugins for Wireshark that can dissect the main headers used by the SAP DIAG protocol too: SecureAuth Labs SAP dissection plug-in and SAP DIAG plugin by Positive Research Center.
- Check for privilege escalations like using some SAP Transaction Codes (tcodes) for low-privilege users:
  - SU01 - To create and maintain the users
  - SU01D - To Display Users
  - SU10 - For mass maintenance
  - SU02 - For Manual creation of profiles
  - SM19 - Security audit - configuration
  - SE84 - Information System for SAP R/3 Authorizations
- Check if you can execute system commands / run scripts in the client.
- Check if you can do XSS on BAPI Explorer

# Testing the web interface

- Crawl the URLs (see discovery phase).
- Fuzz the URLs like in the discovery phase. Here is what http://SAP:50000/index.html looks like:

- Look for common web vulnerabilities (Refer to OWASP Top 10) because there are XSS, RCE, XXE, etc. vulnerabilities in some places.
- Check out Jason Haddix’s “The Bug Hunters Methodology” for testing web vulnerabilities.
- Auth Bypass via verb Tampering? Maybe :)
- Open `http://SAP:50000/webdynpro/resources/sap.com/XXX/JWFTestAddAssignees#` then hit the “Choose” Button and then in the opened window press “Search”. You should be able to see a list of SAP users (Vulnerability Reference: ERPSCAN-16-010 )
- Are the credentials submitted over HTTP? If it is then it is considered as P3 based on Bugcrowd’s Vulnerability Rating Taxonomy: Broken Authentication and Session Management | Weak Login Function Over HTTP. Hint: Check out http://SAP:50000/startPage too or the logon portals :)

- Try `/irj/go/km/navigation/` for possible directory listing or authentication bypass
- http://SAP/sap/public/info contains some juicy information:

# Configuration Parameters

If you have correct login details during the pentest or you have managed to login to SAP GUI using basic credentials, you are able to check the parameter values. Many basic and custom configuration parameter values ​​are considered vulnerabilities.

You can check parameter values ​​both manually and automatically, using scripts (e.g. SAP Parameter Validator).

## Manual Parameter Checking

By navigating to Transaction Code `RSPFPAR`, you can query different parameters and look up their values.

The table below contains the defined parameters and the conditions for which they are distinguished.

For example, if gw/reg_no_conn_info is set to less than 255 (`<255`), then it should be considered as threat. Similarly, if icm/security_log is equal to two (`2`), it will also be a possible threat.

Parameter | Constraint | Description

`snc/enable` | `0` | Enables or disables Secure Network Communication (SNC).
`ucon/rfc/active` | `0` | Activates or deactivates UCON (Unified Connectivity) RFCs.

## Script for Parameter Checking

Due to the number of parameters, it is also possible to export all of them to an .XML file and use the script SAPPV (SAP Parameter Validator), which will check all the above-mentioned parameters and print them values ​​with appropriate distinction.

    ./SAPPV.sh EXPORT.XML

- Try to use some known exploits (check out Exploit-DB) or attacks like the old but goodie “SAP ConfigServlet Remote Code Execution” in the SAP Portal:

    http://example.com:50000/ctc/servlet/com.sap.ctc.util.ConfigServlet?param=com.sap.ctc.util.FileSystemConfig;EXECUTE_CMD;CMDLINE=uname -a

- Before running the `start` command on the bizploit script at the Discovery phase, you can also add the following for performing vulnerability assessment:

    bizploit> plugins
    bizploit/plugins> vulnassess all
    bizploit/plugins> vulnassess config bruteLogin
    bizploit/plugins/vulnassess/config:bruteLogin> set type defaultUsers
    bizploit/plugins/vulnassess/config:bruteLogin> set tryHardcodedSAPStar True
    bizploit/plugins/vulnassess/config:bruteLogin> set tryUserAsPwd True
    bizploit/plugins/vulnassess/config:bruteLogin> back
    bizploit/plugins> vulnassess config registerExtServer
    bizploit/plugins/vulnassess/config:registerExtServer> set tpname evilgw
    bizploit/plugins/vulnassess/config:registerExtServer> back
    bizploit/plugins> vulnassess config checkRFCPrivs
    bizploit/plugins/vulnassess/config:checkRFCPrivs> set checkExtOSCommands True
    bizploit/plugins/vulnassess/config:checkRFCPrivs> back
    bizploit/plugins> vulnassess config icmAdmin
    bizploit/plugins/vulnassess/config:icmAdmin> set adminURL /sap/admin

    bizploit/plugins> start
    bizploit/plugins> back
