PoC exploit for CVE-2021-38699. The target product/service is Java, and the vulnerability class/vector is XXE (XML External Entity) injection. The probable entry point is the `XXEinjector.rb` script, which is a Ruby script that automates the exploitation of XXE vulnerabilities using direct and out of band methods. The execution context is a Ruby script that can be run from the command line, and the typical invocation is by specifying the required parameters, such as the host, file, and path to enumerate. The expected impact is remote code execution, and observable network artifacts include the use of out of band protocols such as FTP, HTTP, and Gopher.
