Burp plugin not working on Python >= 3.12 due to import from deprecated distutils

[msecrfe]

The Burp plugin cannot be used because it attempts to import distutils.util, but distutils is deprecated since Python 3.12:

$ faraday-cli tool report report.xml -w CENSORED --create-workspace --plugin-id burp
Cant load plugin module: burp [No module named 'distutils']
Invalid Plugin: burp

The code block in question in plugin.py only attempts to parse a bool from str in decode_binary_node:

def decode_binary_node(self, node):
        """
        Finds a subnode matching `path` and returns its inner text if
        it has no base64 attribute or its base64 decoded inner text if
        it has it.
        """
        if node is not None:
            encoded = distutils.util.strtobool(node.get('base64', 'false'))
            if encoded:
                res = base64.b64decode(node.text).decode('utf-8', errors="backslashreplace")
            else:
                res = node.text
            return "".join([ch for ch in res if ord(ch) <= 128])
        return ""

Instead of using distutils.util.strtobool, I suggest a "stupid" bool parser that would not have any dependencies:

    def strtobool(self, some_str: str) -> bool:
        if some_str.lower() in ["true", "yes", "wahr", "1"]:
            return True
        elif some_str.lower() in ["false", "no", "falsch", "0"]:
            return False
        else:
            raise ValueError(f"Cannot parse str to bool: {some_str}")

This can then be called by decode_binary_node:

    def decode_binary_node(self, node):
        """
        Finds a subnode matching `path` and returns its inner text if
        it has no base64 attribute or its base64 decoded inner text if
        it has it.
        """
        if node is not None:
            encoded = self.strtobool(node.get('base64', 'false'))
            if encoded:
                res = base64.b64decode(node.text).decode('utf-8', errors="backslashreplace")
            else:
                res = node.text
            return "".join([ch for ch in res if ord(ch) <= 128])
        return ""
