SAP inasimama kwa Systems Applications and Products in Data Processing. SAP, kwa ufafanuzi, pia ni jina la programu ya ERP (Enterprise Resource Planning) pamoja na jina la kampuni. Mfumo wa SAP unajumuisha moduli kadhaa zilizounganishwa kabisa, ambazo hufunika karibu kila upande wa usimamizi wa biashara.
Kila kifaa cha SAP (au SID) kimeundwa na tabaka tatu: database, application na presentation), kila mandhari kawaida inajumuisha vifaa vinne: dev, test, QA na production. Kila moja ya tabaka hizo inaweza kutumiwa kwa kiwango fulani, lakini athari kubwa inaweza kupatikana kwa kuishambulia database.
Kila kifaa cha SAP kimegawanywa katika wateja. Kila mmoja ana mtumiaji SAP*, sawa na "root" wa programu. Baada ya uundaji wa awali, mtumiaji huyu SAP* anapata nenosiri la msingi: "060719992" (nenosiri zaidi la msingi hapa chini). Ungeshangaa kama ungejua mara ngapi hivi nenosiri hazibadilishwi katika mazingira ya majaribio au maendeleo!
Jaribu kupata ufikiaji wa kabati la seva yoyote ukitumia jina la mtumiaji <SID>adm. Kuvunja kwa nguvu kunaweza kusaidia, hata hivyo kuna uwezekano wa kuwepo kwa mfumo wa Kufunga Akaunti.
Angalia Upeo wa Maombi au Muhtasari wa Programu kwa ajili ya majaribio. Chukua maelezo ya majina ya mwenyeji au vifaa vya mfumo kwa ajili ya kuunganisha kwenye SAP GUI.
Tumia OSINT (intelejensia ya chanzo wazi), Shodan na Google Dorks kuchunguza faili, subdomains, na taarifa muhimu ikiwa programu inaonekana mtandaoni au ni ya umma:
Tumia nmap kuangalia mabano yaliyofunguliwa na huduma zinazojulikana (routa za sap, webdynpro, huduma za wavuti, seva za wavuti, nk.)
Tembelea URL ikiwa kuna seva ya wavuti inayotumika.
Fanya majaribio ya kufikia mabara (unaweza kutumia Burp Intruder) ikiwa ina seva za wavuti kwenye mabara fulani. Hapa kuna orodha nzuri za maneno zinazotolewa na Mradi wa SecLists kwa kutafuta Njia za ICM za SAP za chaguo-msingi na mabara au faili zingine za kuvutia:
Tumia moduli ya Metasploit ya SAP SERVICE DISCOVERY ya ziada kwa kuhesabu mifano/huduma/vipengele vya SAP:
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'

Chalula Wireshark kisha thibitisha kwa mteja (SAP GUI) kutumia sifa ulizopata kwa sababu baadhi ya wateja hutuma sifa bila SSL. Kuna programu-jalizi mbili maarufu za Wireshark ambazo zinaweza kuchambua vichwa vikuu vinavyotumiwa na itifaki ya SAP DIAG pia: Programu-jalizi ya uchambuzi wa SAP ya SecureAuth Labs na programu-jalizi ya SAP DIAG ya Positive Research Center.
Angalia kwa ajili ya kuongeza mamlaka kama kutumia baadhi ya Msimbo wa Shughuli za SAP (tcodes) kwa watumiaji wenye mamlaka ya chini:
SU01 - Kujenga na kudumisha watumiaji
SU01D - Kuonyesha Watumiaji
SU10 - Kwa matengenezo ya wingi
SU02 - Kwa uundaji wa mikono wa maelezo
SM19 - Ukaguzi wa usalama - usanidi
SE84 - Mfumo wa Taarifa kwa Ruhusa za SAP R/3
Angalia kama unaweza kutekeleza amri za mfumo / kukimbia hati kwenye mteja.
Angalia kama unaweza kufanya XSS kwenye BAPI Explorer
Jaribio la kiolesura cha wavuti
Tembelea URL (angalia hatua ya ugunduzi).
Fanya Fuzz kwenye URL kama ilivyokuwa kwenye hatua ya ugunduzi. Hapa ndio jinsi http://SAP:50000/index.html inavyoonekana:
Tafuta mapungufu ya kawaida ya wavuti (Rejea kwa OWASP Top 10) kwa sababu kuna mapungufu ya XSS, RCE, XXE, nk. katika baadhi ya maeneo.
Angalia mbinu ya Jason Haddix ya “The Bug Hunters Methodology” kwa ajili ya kufanya majaribio ya mapungufu ya wavuti.
Uthibitishaji wa Bypass kupitia kuhariri maneno? Labda :)
Fungua http://SAP:50000/webdynpro/resources/sap.com/XXX/JWFTestAddAssignees# kisha bonyeza kitufe cha "Chagua" na kisha kwenye dirisha lililofunguliwa bonyeza "Tafuta". Unapaswa kuweza kuona orodha ya watumiaji wa SAP (Rejea ya Udhaifu: ERPSCAN-16-010)
Je, sifa zinawasilishwa kupitia HTTP? Ikiwa ndivyo basi inachukuliwa kama P3 kulingana na Uainishaji wa Udhaifu wa Bugcrowd: Uthibitishaji Uliovunjika na Usimamizi wa Kikao | Kazi Dhaifu ya Kuingia Kupitia HTTP. Kiashiria: Angalia http://SAP:50000/startPage pia au malango ya kuingia :)
Jaribu /irj/go/km/navigation/ kwa orodha ya saraka inayowezekana au kwa kuzidi uthibitishaji
Angalia ikiendeshwa kwenye seva au teknolojia za zamani kama Windows 2000.
Panga mashambulizi / udukuzi uwezekanao, kuna moduli nyingi za Metasploit kwa ugunduzi wa SAP (moduli za ziada) na udhaifu:
