Inleiding oor SAP

SAP staan vir Systems Applications and Products in Data Processing. SAP, per definisie, is ook die naam van die ERP (Enterprise Resource Planning) sagteware sowel as die naam van die maatskappy. Die SAP-stelsel bestaan uit 'n aantal volledig geïntegreerde modules, wat feitlik elke aspek van besigheidsbestuur dek.

Elke SAP-instantie (of SID) bestaan uit drie lae: databasis, toepassing en aanbieding), elke landskap bestaan gewoonlik uit vier instanties: dev, toets, QA en produksie. Elke van die lae kan tot 'n sekere mate uitgebuit word, maar die meeste effek kan verkry word deur die databasis aan te val.

Elke SAP-instantie is verdeel in kliënte. Elke een het 'n gebruiker SAP*, die toepassing se ekwivalent van “root”. By die aanvanklike skepping, ontvang hierdie gebruiker SAP* 'n standaard wagwoord: “060719992” (meer standaard wagwoorde hieronder). Jy sal verbaas wees as jy weet hoe dikwels hierdie wagwoorde nie in toets- of dev-omgewings verander word nie!

Probeer om toegang te verkry tot die skulp van enige bediener met gebruikersnaam <SID>adm. Bruteforcing kan help, maar daar kan 'n rekening sluiting meganisme wees.

Ontdekking

Volgende afdeling is meestal van https://github.com/shipcod3/mySapAdventures van gebruiker shipcod3!

Kyk na die Toepassing Omvang of Program Oorsig vir toetsing. Neem kennis van die hostnames of stelselinstanties vir verbinding met SAP GUI.
Gebruik OSINT (open source intelligence), Shodan en Google Dorks om te kyk vir lêers, subdomeine, en sappige inligting as die toepassing internet-gestig of publiek is:

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

Hier is hoe http://SAP:50000/irj/portal lyk

Gebruik nmap om oop poorte en bekende dienste (sap routers, webdnypro, webdienste, webbedieners, ens.) te kontroleer.
Krap die URL's as daar 'n webbediener aan die gang is.
Fuzz die gidse (jy kan Burp Intruder gebruik) as dit webbedieners op sekere poorte het. Hier is 'n paar goeie woordlyste wat deur die SecLists Project verskaf word om standaard SAP ICM Paaie en ander interessante gidse of lêers te vind:

Gebruik die SAP SERVICE DISCOVERY bykomende Metasploit module om SAP instansies/dienste/komponente te noem:

msf > use auxiliary/scanner/sap/sap_service_discovery
msf auxiliary(sap_service_discovery) > show options
Module options (auxiliary/scanner/sap/sap_service_discovery):

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

Voer Wireshark uit en autentiseer by die kliënt (SAP GUI) met die akrediteer wat jy gekry het omdat sommige kliënte akrediteer sonder SSL oordra. Daar is twee bekende plugins vir Wireshark wat die hoofkoppe wat deur die SAP DIAG protokol gebruik word, kan ontleed: SecureAuth Labs SAP ontledingsplugin en SAP DIAG plugin deur Positive Research Center.
Kyk vir privilige eskalasies soos om sommige SAP Transaksie Kodes (tcodes) vir lae-privilege gebruikers te gebruik:
SU01 - Om die gebruikers te skep en te onderhou
SU01D - Om Gebruikers te Vertoon
SU10 - Vir massa onderhoud
SU02 - Vir Handmatige skepping van profiele
SM19 - Sekuriteitsoudit - konfigurasie
SE84 - Inligtingstelsel vir SAP R/3 Magtigings
Kyk of jy stelselskommando's kan uitvoer / skripte in die kliënt kan loop.
Kyk of jy XSS op BAPI Explorer kan doen

Toetsing van die webkoppelvlak

Kruid die URL's (sien ontdekking fase).
Fuzz die URL's soos in die ontdekking fase. Hier is hoe http://SAP:50000/index.html lyk:

Soek vir algemene web kwesbaarhede (Verwys na OWASP Top 10) omdat daar XSS, RCE, XXE, ens. kwesbaarhede in sommige plekke is.
Kyk na Jason Haddix se “The Bug Hunters Methodology” vir die toetsing van web kwesbaarhede.
Auth Bypass via werkwoord Manipulasie? Miskien :)
Maak http://SAP:50000/webdynpro/resources/sap.com/XXX/JWFTestAddAssignees# oop en druk dan die “Kies” knoppie en druk dan in die geopende venster “Soek”. Jy behoort 'n lys van SAP gebruikers te kan sien (Kwesbaarheid Verwysing: ERPSCAN-16-010)
Word die akrediteer oor HTTP ingedien? As dit is, word dit as P3 beskou gebaseer op Bugcrowd se Kwesbaarheid Gradering Taksonomie: Gebroke Autentisering en Sessie Bestuur | Swak Inlog Funksie Oor HTTP. Wenke: Kyk ook na http://SAP:50000/startPage of die aanmeldportale :)

Konfigurasieparameters

As jy korrekte aanmeldbesonderhede tydens die pentest het of jy daarin geslaag het om in te log op SAP GUI met basiese akreditasies, kan jy die parameterwaardes nagaan. Baie basiese en pasgemaakte konfigurasieparameterwaardes word as kwesbaarhede beskou.

Jy kan parameterwaardes beide handmatig en outomaties nagaan, met behulp van skripte (bv. SAP Parameter Validator).

Handmatige Parameter Nagaan

Deur na Transaksiekode RSPFPAR te navigeer, kan jy verskillende parameters opsoek en hul waardes nagaan.

Die tabel hieronder bevat die gedefinieerde parameters en die voorwaardes waarvoor hulle onderskei word.

Byvoorbeeld, as gw/reg_no_conn_info op minder as 255 (<255) gestel is, moet dit as 'n bedreiging beskou word. Net so, as icm/security_log gelyk is aan twee (2), sal dit ook 'n moontlike bedreiging wees.

Probeer om 'n paar bekende exploits te gebruik (kyk na Exploit-DB) of aanvalle soos die ou maar goeie “SAP ConfigServlet Remote Code Execution” in die SAP Portal:

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

Voordat jy die start opdrag op die bizploit skrip in die Ontdekking fase uitvoer, kan jy ook die volgende byvoeg om kwesbaarheidsevaluering uit te voer:

bizploit> plugins
bizploit/plugins> vulnassess all
bizploit/plugins> vulnassess config bruteLogin
bizploit/plugins/vulnassess/config:bruteLogin> set type defaultUsers
