Technical Details & Description:
==============================
1.1
A sql injection web vulnerability has been discovered in the official E-Journal (ID) content management system.
The vulnerability allows remote attackers to execute own sql commands by usage of a vulnerable serivce value.
The vulnerability is located in the id value of the jurnal.php file. Remote attackers are able to execute own
sql commands by usage of a GET method request with manipulated id value. Remote attackers are able to read
database information by execution of own sql commands. The vulnerability is located in the client-side and the
request method to execute sql commands is GET.
The security risk of the sql vulnerability is estimated as high with a cvss (common vulnerability scoring system) count of 7.0.
Exploitation of the sql injection web vulnerability does not require a privileged application user account or user interaction.
Successful exploitation of the remote vulnerability results in database management system and web-application compromise.
Request Method(s):
[+] GET
Vulnerable Module(s):
[+] jurnal
Vulnerable File(s):
[+] jurnal.php
Vulnerable Parameter(s):
[+] id
1.2
A privilege escalation vulnerability has been discovered in the official E-Journal (ID) content management system.
The vulnerability allows an attacker to escalate of the restricted privileges, to gain for example higher access controls.
The privilege escalation vulnerability is located in tambah value of the URL input in the data.php file. Remote attackers can switch
the menu to escalte with privileges by adding a new administrator account. The vulnerability is located on the application-side and
the request method to inject is POST.
The security risk of the privilege escalation vulnerability is estimated as high with a cvss (common vulnerability scoring system) count of 6.9.
Exploitation of the privilege escalation web vulnerability requires a low privileged application user account and no user interaction.
Successful exploitation of the remote vulnerability results in information leaking, database management system- and web-application -compromise.
Request Method(s):
[+] POST
Vulnerable Module(s):
[+] URL
Vulnerable File(s):
[+] data.php
Vulnerable Parameter(s):
[+] tambah
Proof of Concept (PoC):
=======================
The vulnerabilities can be exploited by remote attackers without privileged application user account and user interaction.
For security demonstration or to reproduce the security vulnerability follow the provided information and steps below to continue.

Note: This E-Journal CMS has 2 versions, The Old Version doesn't have informasi.php (Informasi Menu).
1.1
POC#1: SQL Injection
http://[Site]/[Path]/jurnal.
Reference Url(s):
http://e-journal.xxx.ac.id/
http://www.ejournal-xxx.com/
http://e-journal.xxx.ac.id/
http://ejurnal.xxx.ac.id/
http://ejournal.xxx.ac.id/
1.2
PoC#2: Privilege Escalation
You can create a new administrator account by usage of the following trick.
For Example my Target url is : http://www.ejournal-xxx.com/
Step1: Add data.php?tambah=dosen in the URL. So in this case the URL washttp://www.ejournal-xxx.com/
Step2: Then you can see this notice : "ANDA TIDAK BERHAK MENGAKSES HALAMAN INI. SILAHKAN ANDA LOGIN SEBAGAI ADMINISTRATOR".
Ignore that Notice and click Admin Menu. Screenshot #1 : http://i59.tinypic.com/54he2b.
Step3: Successful exploited! Now you can add an Administrator Account. Screenshot #2 :http://i59.tinypic.com/
Solution - Fix & Patch:
=======================
1.1
The vulnerability can be patched by usage of a prepared statement. Encode and parse the vulnerable id value in the jurnal.php file to prevent sql injection attacks.
1.2
Restrict the URL parameter input to prevent unauthorized account adds. Parse the URL value and encode the input restrict the url to a local source.
Security Risk:
==============
1.1
The security risk of the remote sql injection web vulnerability in the e-journal application is estimated as high. (CVSS 7.0)
1.2
The security risk of the privilege escalation web vulnerability in the URL parameter is estimated as high. (CVSS 6.9)
