Medium


Details:
========
1.1
Multiple persistent input validation vulnerabilities are detected in the car portal v3.0 web application.
The bugs allow remote attackers to implement/inject malicious script code on the application side (persistent).
Successful exploitation of the vulnerability can lead to session hijacking (manager/admin) or stable (persistent) 
context manipulation. Exploitation requires low user inter action.

Vulnerable Module(s):
    [+] Post a new vehicle  - PWRS & Description field

file will save on the sever as file.php.
Successful exploitation can result in malware or malicious web shell upload which results in a system comrpomise at the end.


Risk:
=====
1.1
