Details:
========
Multiple persistent input validation vulnerabilities are detected in the Kayako Fusion v4.51.1891 Web Application.
The vulnerability typus allows an attacker to inject own malicious script code in the vulnerable module on application 
side (persistent).

The first vulnerability is located in the Tickets section when processing to request via the the `Escalation` module 
the bound 
vulnerable add_tags & remove_tags application parameters. The persistent injected script code will be executed directly 
out of 
the `add` section when processing to edit  the earlier inserted dbms context.

The secound vulnerability is located in the Base section when processing to request via the `Manage` module the bound 
vulnerable 
`CustomFieldGroup > eMail` application listing. The persistent injected script code will be executed directly out of 
the `usergroup` 
listing when processing to manage the earlier inserted dbms context.

The third vulnerability is located in the Live-Chat section when processing to request via the `Manage` module the 
bound vulnerable 
`Visitor Group Title` application listing. The persistent injected script code will be executed directly out of the 
`Visitor Group` 
listing when processing to manage the earlier inserted dbms context.

The 4th vulnerability is located in the LanguagePhrase section when processing to request via the `Manage` module the 
bound vulnerable 
`search query` (string) application listing. The persistent injected script code will be executed directly out of the 
`Search Query` 
listing when processing to manage the earlier inserted dbms context.

The 5th vulnerability is located in the Staff section when processing to request via the `Manage or Insert` module the 
bound vulnerable 
`staff name or staff group` application parameters. The persistent injected script code will be executed directly out 
of the `Staff`- or 
`Staff Edit` listing  when processing to manage the earlier inserted dbms context.

The vulnerabilities can be exploited with a privileged application user account and low or medium required user 
interaction. 
Successful exploitation of the vulnerability result in persistent session hijacking, persistent phishing, external 
redirect, external malware 
loads and persistent vulnerable module context manipulation.

Proof of Concept:
=================
The persistent inut validation vulnerabilities can be exploited by restricted low or medium privileged application user 
account with low 
required user interaction. For demonstration or reproduce ...
