Abstract:
=========
Vulnerability-Lab Team (Chokri B.A.) discovered Multiple Web Vulnerabilities on the resource management tool Achievo v1.4.3.


Report-Timeline:
================
2012-01-30:	Public or Non-Public Disclosure


Status:
========
Published


Exploitation-Technique:
=======================
Remote


Severity:
=========
Critical


Details:
========
1.1
A blind SQL vulnerability is detected in the resource management tool Achievo v1.4.3 Content Management System. 
The sql injection bug allows remote attackers to inject own sql commands on the affected (vulnerable) web application dbms.
The vulnerability is located in every module in the atkstackid (session) module with the bound vulnerable id parameter request.
Exploitation requires no user interaction or privileged application user account. Successful exploitation of the vulnerability 
results in web application and dbms compromise via sql injection attack. 

Vulnerable Module(s): (Example)
				[+] Download vcard
				[+] ... & all -id bound requests


Vulnerable Parameter(s):
				[+] tkstackid session - ID


1.2
Multiple persistent input validation web vulnerabilities are detected in the resource management tool Achievo v1.4.3.
The bug allows remote attacker to implement/ inject own malicious script code on the application side (persistent).

The first vulnerability is located in the user preferences module with the bound vulnerable search all parameter request.
The secound vulnerability is located in the projects module with the bound vulnerable fieldlabel parameter request

Successful exploitation of the vulnerability results in persistent session hijacking (user/mod/admin), persistent phishing, 
persistent redirects or malware loads and persistent web context manipulation. Exploitation requires low privileged 
application user account and low or medium required user interaction.

Vulnerable Module(s):
				[+] Users preferences
				[+] Projects


Vulnerable Parameter(s):
				[+] Search All
				[+] Name


Proof of Concept:
=================
1.1
The sql injection vulnerability can be exploited by remote attackers without user interaction and without privileged application user account. 
For demonstration or reproduce ...

1.2
The persistent web vulnerabilities can be exploited by remote attackers with low required user inter action. For demonstration or reproduce ...

Risk:
=====
1.1
The security risk of the persistant xss vulnerabilities are estimated as medium(+).

1.2
The security risk of the blind sql injection vulnerabilities are estimated as high(+).
