Technical Details & Description:
================================
1.1
Multiple remote sql-injection web vulnerabilities has been discovered in
the official  Project Open v5.0.3 CMS web-application.
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 `order_by`,
`forum_order_by` and `audit_id` parameters of the
`./intranet-expenses/index`
and `./intranet-audit/view` modules. 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 order or id parameter to compromise the dbms. Multiple
unhandled
and broken sql queries are visible as default debug to output for
different roles 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):
[+] GET

Vulnerable Module(s):
[+] ./intranet-expenses/index
[+] ./intranet-audit/view

Vulnerable Parameter(s):
[+] forum_order_by
[+] order_by
[+] audit_id



1.2
Multiple non-persistent cross site scripting vulnerabilities has been
discovered in the official  Project Open v5.0.3 CMS web-application.
The vulnerability allows remote attackers to inject own malicious script
codes with non-persistent attack vector to compromise browser
to web-application requests from the client-side.

The cross site scripting web security vulnerabilities are located in the
`bread_crum_path` and `re_path` parameters of the
`./intranet/projects/view` and `./intranet-filestorage` modules. The
request method to inject the malicious script code is
GET and the attack vector of the vulnerability is non-persistent on
client-side.

Remote attackers are able to inject own script codes to the client-side
requested vulnerable web-application parameters. The attack vector of
the vulnerability is non-persistent and the request method to
inject/execute is GET. The vulnerabilities are classic client-side cross
site
scripting vulnerabilities. Successful exploitation of the vulnerability
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):
[+] GET

Vulnerable Module(s):
[+] ./intranet/projects/view
[+] ./intranet-filestorage

Vulnerable Parameter(s):
[+] bread_crum_path
[+] rel_path


Proof of Concept (PoC):
=======================
