Product: WebTitan Appliance Application v3.50.x
Exploitation-Technique:
=======================
Remote
Severity:
=========
High
Details:
========
Multiple persistent input validation vulnerabilities are detected on the
Webtitans Application 3.50x.
The vulnerability allows privileged user accounts to inject malicious
persistent script code to manipulate application requests.
Successful exploitation can result in session hijacking, account steal,
persistent exploitation & persistent context manipulation.
Vulnerable Module(s):
[+] NTP Server (Display)
[+] Extensions / Execute Files
[+] Setup Time
[+] Categories Add/Edit
[+] Add URL
