Spring Cloud Function versions prior to 3.1.7 and 3.2.3 are vulnerable to remote code execution due to using an unsafe evaluation context with user-provided queries. By crafting a request to the application and setting the spring.cloud.function.routing-expression header, an unauthenticated attacker can gain remote code execution. Both patched and unpatched servers will respond with a 500 server error and a JSON encoded message.

To display the available options, load the module within the Metasploit console and run the commands 'show options' or 'show advanced':
msf > use exploit/multi/http/spring_cloud_function_spel_injection
msf exploit(spring_cloud_function_spel_injection) > show targets
...targets...
msf exploit(spring_cloud_function_spel_injection) > set TARGET < target-id >
msf exploit(spring_cloud_function_spel_injection) > show options
...show and set options...
msf exploit(spring_cloud_function_spel_injection) > exploit
Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
