Current stable version of Event Calendar PHP is 1.2 ( Copy of the Vendor Homepage: http://www.eventcalendarphp.com ) Abstract: ========= The Vulnerability Laboratory Research Team discovered multiple web vulnerabilites in Event Calendar PHP 1.2 CMS. Report-Timeline: ================ 2012-06-17: Public Disclosure Status: ======== Published Exploitation-Technique: ======================= Remote Severity: ========= High Details: ======== 1.1 Multiple SQL Injection vulnerabilities are detected in the Funeral Script PHP 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. The vulnerabilities are located in the funeral_script.php & admin.php files and the bound vulnerable parameters orderBy, orderType & hide_cat. Successful exploitation of the vulnerability results in dbms & application compromise. Vulnerable File(s): [+] admin.php [+] preview.php Vulnerable Parameter(s): [+] orderBy [+] orderType 1.2 Multiple persistent input validation vulnerabilities are detected in the Funeral Script PHP Content Management System. The bugs allow remote attackers to implement/inject malicious script code on the application side (persistent). The vulnerabilities are located in the Successful exploitation of the vulnerability can lead to session hijacking (manager/admin) or stable (persistent) context manipulation. Exploitation requires low user inter action & privileged application user account. Vulnerable Section(s): [+] Event - Input & Listing [+] Calender - Input & Listing Vulnerable Module(s): [+] [Calender - Name|Title > Listing] [+] [Event - Name|Title > Listing] Vulnerable Parameter(s): [+] newCal - name [+] newEvent - title 1.3 Multiple non persistent cross site scripting vulnerabilities are detected on the ME Firewall Analyzer v7.2 Application. The vulnerability allows remote attackers to hijack website customer, moderator or admin sessions with medium or high required user inter action or local low privileged user account. Exploitation requires low user inter action or low privileged application user account. The bugs are located in the admin.php & funeral_script.php files with the bound vulnreable parameters orderBy, search, orderType, p, hide_cat & obit_id. Successful exploitation can result in account steal, phishing & client-side content request manipulation. Vulnerable File(s): [+] admin.php [+] preview.php Vulnerable Parameter(s): [+] cal_id, cal_month & cal_year [+] act [+] search Proof of Concept: ================= 1.1 The sql injection vulnerabilities can be exploited by remote attackers with privileged user accounts & without required user inter action. For demonstration or reproduce ... http://127.0.0.1:80/eventcalendar/admin.php?act=calendars&orderType=DESC&search=&orderBy=-1%27[SQL-INJECTION]cal_name&cal_id=2 http://127.0.0.1:80/eventcalendar/admin.php?act=calendars&orderType=-1%27[SQL-INJECTION]&search=&orderBy=cal_name&cal_id=2 http://127.0.0.1:80/eventcalendar/admin.php?act=events&orderType=ASC-1%27[SQL-INJECTION]&orderBy=event_title&cal_id=2 http://127.0.0.1:80/eventcalendar/admin.php?act=events&orderType=ASC&orderBy=-1%27[SQL-INJECTION]event_title&cal_id=2 http://127.0.0.1:80/preview.php?act=calendars&orderType=DESC&search=&orderBy=-1%27[SQL-INJECTION]cal_name&cal_id=2 1.2 The persistent script code inject vulnerability can be exploited by remote attackers with privileged user acctount & low required user inter action. For demonstration or reproduce ... PoC: http://127.0.0.1:80/eventcalendar/admin.php?act=newCal&cal_id=2 http://127.0.0.1:80/eventcalendar/admin.php?act=newEvent&cal_id=2 Note: Inject your persistent script code to the title input fields and watch the vulnerable output listing. 1.3 The client side cross site scripting vulnerabilities can be exploited by remote attackers with medium or high required user inter action. For demonstration or reproduce ...
