Cells Blog CMS v1.1 multiple defects

Title: Cells Blog CMS v1.1-Multiple Web Vulnerabilites
Program Overview:
==================
Cells-blog is a free but powerful mini-blog system. It can run on any web server that can excute PHP script codes.
It comes alone with the SQLite data base so you can copy and play without any installation. Any question please first
Check to the FAQ in the Cells official web site. If you still have question, you can contact with system manager or
Leave a message in our official webite www.cells.tw

Abstract:
Cells Blog v1.1 Content Management System multiple vulnerabilities discovered
 
Technical logs:
==========
1.1
Multiple SQL Injection vulnerabilities are detected in the Cells Blog v1.1 Content Management System.
The vulnerability allows an attacker (remote) or local low privileged user account to inject/execute own SQL commands
On the affected application dbms without user inter action. Successful exploitation of the vulnerability results in dbms
& Application compromise. The SQL injection vulnerabilities are located in multiple files in the main menu and the bound
Parameters bgid, ptid, fmid & id...

Vulnerable Parameter (s ):
[+] Bgid
[+] Ptid
[+] Fmid
[+] Id
 
 
1.2
Multiple persistent input validation vulnerabilities are detected in the Cells Blog v1.1 Content Management System.
The bugs allow remote attackers to implement/inject malicious script code on the application side (persistent ).
Successful exploitation of the vulnerability can lead to session hijacking (manager/admin) or stable (persistent)
Context manipulation. Exploitation requires low user inter action or low privileged application user account.
The bugs are located in the add, save & update input fields. The code is getting executed on the specific listing
Page of after adding via module. If the attacker for example include persistent script code in the album name
Context will be executed out of the album listing page.

Proof of Concept:
========================
1.1
Multiple SQL Injection vulnerabilities are detected in the Cells Blog v1.1 Content Management System.
The vulnerability allows an attacker (remote) or local low privileged user account to inject/execute own SQL commands
On the affected application dbms without user inter action. Successful exploitation of the vulnerability results in dbms
& Application compromise. The SQL injection vulnerabilities are located in multiple files in the main menu and the bound
Parameters bgid, ptid, fmid & id...
 
 
1.1
The SQL injection vulnerability can be exploited by remote attackers without user inter action. For demonstration or reproduce...
 
PoC:
Http: // 127.0.0.1: 1338/cells/fourm. php? Bgid =-1 union select [SQL-INJECTION] --
Http: // 127.0.0.1: 1338/cells/fourm. php? Bgid = 1 & fmid =-1 union select [SQL-INJECTION] --
Http://www.bkjia.com/cells/pub_readpost.php? Bgid = 1 & ptid =-1 union select [SQL-INJECTION] --
Http: // 127.0.0.1: 1338/cells/pub_readpost.php? Bgid =-1 union select [SQL-INJECTION] --
Http: // 127.0.0.1: 1338/cells/pub_nmsg.php? Report = pst & bgid = 1 & fmid = 8 & ptid =-1 union select [SQL-INJECTION] --
Http: // 127.0.0.1: 1338/cells/pub_openpic.php? Fnid = 10 & bgid = 1 & fmid =-1 union select [SQL-INJECTION] --
Http: // 127.0.0.1: 1338/cells/my_newpost.php? Fmid =-1 union select [SQL-INJECTION] --
 
 
 
1.2
The persistent input validation vulnerabilities can be exploited by local low privileged user account with low required
User inter action. For demonstration or reproduce...
 
The vulnerability can be reproduce by injecting your own persistent script code in the update link field, add name field
Or url save input field. The persistent code will be executed (persistent) out of the listing context of the vulnerable module.
 
 
Risk:
=====
1.1
The security risk of the SQL injection vulnerabilities are estimated as critical.
 
1.2
The security risk of the persistent input validation vulnerabilities are estiamted as medium (+)
