Technical Details & Description:
================================
A remote sql-injection web vulnerability has been discovered in the
official iJoomla com_adagency 6.0.9 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 and web-server system.

The sql injection vulnerability is located in the `status_select`
parameter of the `option=com_adagency` module. The request method to
inject or execute commands is GET and the attack vector is located on
the client-side. Attackers with low privileged accounts are able
to inject own sql queries via insecure transmitted `status_select`
parameter to compromise the dbms.

Exploitation of the remote sql injection vulnerability requires no user
interaction and only a low 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):
[+] option=com_adagency

Vulnerable Parameter(s):
[+] status_select


Proof of Concept (PoC):
=======================
The remote sql injection web vulnerability can be exploited by remote
attackers without user interaction.
