Vulnerability Disclosure Timeline: ================================== 2012-05-10: Public or Non-Public Disclosure Discovery Status: ================= Published Exploitation Technique: ======================= Remote Severity Level: =============== High Technical Details & Description: ================================ 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 (PoC): ======================= 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 ... >“ >" ... 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 Reference(s): http://travelon.xxx.com/upload/holiday/hi9223test.php Security 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(-).
