1.1
Multiple Input Validation vulnerabilities are detected on hte volksbank portal
& banking website.
Remote attackers can include malicious persistent script-codes on application
side of the vulnerable affected modules.
The vulnerability allows an attacker also to hijack not expired customers
sessions.

1.2
Multiple Input Validation vulnerabilites are detected on client-side of the
volksbank portal & banking website.
Remote attackers can hijack customer sessions/cookies via cross site scripting
with high required user inter action.
Vulnerable Module(s):
[+] Search
Picture(s):
../volksbank.com3.png
../volksbank.com4.png
../volksbank.com5.png
1.3
A redirection vulnerability allows an attacker to redirect the website or
implement phishing routines via ?url request on client-side.
Vulnerable Module(s):
[+] Kurse & Banking
[+] IPO News Index

../volksbank.com7.png
Proof of Concept:
=================
The vulnerabilites can be exploited by remote attackers or local privileged
user accounts. For demonstration or reproduce ...

Risk:
=====
1.1
The security risk of the persistent vulnerabilities are estimated as high(-)
because of low required user inter action.
1.2
The security risk of the non-persistent vulnerabilities are estimated as
medium(-) because of high required user inter action.
1.3
The security risk of the redirect vulnerability is estimated as low.
