Utangulizi kuhusu SAP

SAP inasimama kwa Mifumo ya Maombi na Bidhaa katika Usindikaji wa Takwimu. SAP, kwa ufafanuzi, pia ni jina la programu ya ERP (Usimamizi wa Rasilimali za Kijamii) pamoja na jina la kampuni. Mfumo wa SAP unajumuisha moduli kadhaa zilizounganishwa kikamilifu, ambazo zinashughulikia karibu kila kipengele cha usimamizi wa biashara.

Kila mfano wa SAP (au SID) unajumuisha tabaka tatu: hifadhidata, programu na uwasilishaji), kila mandhari kwa kawaida ina mifano minne: dev, test, QA na production. Kila moja ya tabaka inaweza kutumika kwa kiwango fulani, lakini athari kubwa zaidi inaweza kupatikana kwa kushambulia hifadhidata.

Kila mfano wa SAP umegawanywa katika wateja. Kila mmoja ana mtumiaji SAP*, sawa na “root” wa programu. Wakati wa kuundwa kwa awali, mtumiaji huyu SAP* anapata nenosiri la default: “060719992” (nenosiri zaidi la default hapa chini). Utashangazwa ukijua ni mara ngapi nenosiri haya hayabadilishwi katika mazingira ya test au dev!

Jaribu kupata ufikiaji wa shell ya seva yoyote kwa kutumia jina la mtumiaji <SID>adm. Bruteforcing inaweza kusaidia, hata hivyo kunaweza kuwa na utaratibu wa Kufunga Akaunti.

Ugunduzi

Angalia Mipango ya Programu au Muhtasari wa Programu kwa ajili ya majaribio. Kumbuka majina ya mwenyeji au mifano ya mfumo kwa kuungana na SAP GUI.
Tumia OSINT (intelligence ya chanzo wazi), Shodan na Google Dorks kuangalia faili, subdomains, na taarifa za kuvutia ikiwa programu ina uso wa Mtandao au ni ya umma:

SAP Logon screen

Tumia nmap kuangalia bandari zilizo wazi na huduma zinazojulikana (sap routers, webdnypro, web services, web servers, nk.)
Tembelea URLs ikiwa kuna seva ya wavuti inayofanya kazi.
Fuzz directories (unaweza kutumia Burp Intruder) ikiwa ina seva za wavuti kwenye bandari fulani. Hapa kuna orodha nzuri za maneno zilizotolewa na Mradi wa SecLists kwa ajili ya kutafuta Njia za ICM za SAP za default na directories au faili nyingine za kuvutia:

Kimbia Wireshark kisha uthibitishe kwa mteja (SAP GUI) ukitumia akidi ulizopata kwa sababu baadhi ya wateja hupeleka akidi bila SSL. Kuna plugins mbili zinazojulikana za Wireshark ambazo zinaweza kuchambua vichwa vikuu vinavyotumika na protokali ya SAP DIAG pia: SecureAuth Labs SAP dissection plug-in na SAP DIAG plugin by Positive Research Center.
Angalia kwa kupandisha mamlaka kama kutumia baadhi ya SAP Transaction Codes (tcodes) kwa watumiaji wenye mamlaka ya chini:
SU01 - Kuunda na kudumisha watumiaji
SU01D - Kuonyesha Watumiaji
SU10 - Kwa matengenezo ya wingi
SU02 - Kwa uundaji wa mikakati kwa mkono
SM19 - Ukaguzi wa usalama - usanidi
SE84 - Mfumo wa Taarifa kwa SAP R/3 Mamlaka
Angalia kama unaweza kutekeleza amri za mfumo / kukimbia scripts katika mteja.
Angalia kama unaweza kufanya XSS kwenye BAPI Explorer

Kujaribu kiolesura cha wavuti

Tembea URLs (ona awamu ya kugundua).
Fuzz URLs kama katika awamu ya kugundua. Hapa kuna jinsi http://SAP:50000/index.html inavyoonekana:

SAP Index Page

Tafuta udhaifu wa kawaida wa wavuti (Rejelea OWASP Top 10) kwa sababu kuna XSS, RCE, XXE, nk. udhaifu katika baadhi ya maeneo.
Angalia Jason Haddix’s “The Bug Hunters Methodology” kwa ajili ya kujaribu udhaifu wa wavuti.
Auth Bypass kupitia verb Tampering? Labda :)
Fungua http://SAP:50000/webdynpro/resources/sap.com/XXX/JWFTestAddAssignees# kisha bonyeza kitufe cha “Chagua” na kisha katika dirisha lililofunguka bonyeza “Tafuta”. Unapaswa kuwa na uwezo wa kuona orodha ya watumiaji wa SAP (Rejeleo la Udhaifu: ERPSCAN-16-010 )
Je, akidi zimewasilishwa kupitia HTTP? Ikiwa ndivyo, basi inachukuliwa kama P3 kulingana na Bugcrowd’s Vulnerability Rating Taxonomy: Uthibitishaji Uliovunjika na Usimamizi wa Kikao | Kazi ya Kuingia Dhaifu Juu ya HTTP. Kidokezo: Angalia pia http://SAP:50000/startPage au milango ya kuingia :)

SAP Start Page

Jaribu /irj/go/km/navigation/ kwa orodha ya saraka inayowezekana au kupita uthibitisho

Configuration Parameters

Ikiwa una maelezo sahihi ya kuingia wakati wa pentest au umeweza kuingia kwenye SAP GUI kwa kutumia akidi za msingi, unaweza kuangalia thamani za vigezo. Thamani nyingi za vigezo vya msingi na vya kawaida zinachukuliwa kama udhaifu.

Unaweza kuangalia thamani za vigezo kwa njia ya mikono na kiotomatiki, kwa kutumia scripts (e.g. SAP Parameter Validator).

Manual Parameter Checking

Kwa kuhamasisha kwenye Msimbo wa Muamala RSPFPAR, unaweza kuuliza vigezo tofauti na kutafuta thamani zao.

Jedwali hapa chini lina vigezo vilivyofafanuliwa na masharti ambayo yanatofautishwa.

Kwa mfano, ikiwa gw/reg_no_conn_info imewekwa chini ya 255 (<255), basi inapaswa kuzingatiwa kama tishio. Vivyo hivyo, ikiwa icm/security_log ni sawa na mbili (2), pia itakuwa tishio linalowezekana.
