Utangulizi kuhusu SAP

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 zinashughulikia karibu kila upande wa usimamizi wa biashara.

Kila kifaa cha SAP au SID kimeundwa na safu tatu: database, application na presentation), kila mandhari kawaida ina vipande vinne: dev, test, QA na production. Kila safu inaweza kutumiwa kwa kiwango fulani, lakini athari kubwa inaweza kupatikana kwa kushambulia database.

Kila kifaa cha SAP kimegawanywa katika wateja. Kila mmoja ana mtumiaji SAP*, sawa na "root" wa programu. Baada ya kuundwa kwa mara ya kwanza, mtumiaji huyu SAP* anapata nenosiri la msingi: "060719992" nenosiri zaidi la msingi hapa chini. Ungeshangaa kama ungejua mara ngapi hizi 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 Programu au Maelezo ya Programu kwa ajili ya majaribio. Chukua maelezo ya majina ya mwenyeji au vipande vya mfumo kwa ajili ya kuunganisha kwenye SAP GUI.

Chukua Wireshark kisha thibitisha kwa mteja SAP GUI ukitumia 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.
