Description

Currently, when the input yml technique contains a escaped non-printable character like \b, it gets rendered into the output files, and in particular the generated metdata.xml is invalid (non-printable characters are forbidden in XML 1.0 and must be escaped in XML 1.1).

id: "test" 
name: "Test" 
version: "0.1" 
items:
  - method: command_execution
    params:
      command: "my command \b is here"

The \b is interpreted as backspace char in output files.

We need to:

  • Check the behavior in 7.3
  • Prevent our XML output from including forbidden chars. Check with upstream quick_xml lib which should not accept it.
  • Implement a simple fix for RC 2

In 7.3:

It is escaped a second time in the JSON:

        {
          "name":"command",
          "value":"toto\\btiti" 
        }

      <REPORTKEYS>
        <VALUE id="4f3a093c-3be0-4aef-9ff3-09ffcca58e72">toto\btiti</VALUE>
      </REPORTKEYS>

 iytfr_gm_0("Command execution", "toto\\btiti", "4f3a093c-3be0-4aef-9ff3-09ffcca58e72", "toto\\btiti")

The \b is kept in output files (and escaped once more in the .cf file).
