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.
Vulnerable Section(s):
[+] Tickets
[+] Base
[+] Live-Chat
[+] LanguagePhrase
[+] Staff
Vulnerable Module(s):
[+] Escalation/Insert - (Tickets)
[+] CustomFieldGroup/Manage - (Base)
[+] Staff/Insert & /Staff/Edit/1 - (Base)
[+] StaffGroup/Insert - (Base)
[+] LiveChat/Group/Manage - (Live-Chat)
[+] Manage/0 - Search - (LanguagePhrase)
Vulnerable Parameter(s):
[+] Add tags & remove tags
[+] eMail User - Listing (Profile All Sections)
[+] Visitor Group Title & Group Color
[+] Search Query
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 ...
