Current stable version of GuestBook Script PHP is 1.5 ( Copy of the Vendor Homepage: http://www.guestbookscripts.com ) Abstract: ========= The Vulnerability Laboratory Research Team discovered multiple different web vulnerabilites in GuestBook Scripts PHP 1.5 CMS. Report-Timeline: ================ 2012-06-11: Public or Non-Public Disclosure Status: ======== Published Exploitation-Technique: ======================= Remote Severity: ========= High Details: ======== 1.1 Multiple SQL Injection vulnerabilities are detected in the GuestBook Scripts PHP 1.5 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 vulnerabilities are located in the guestbook.php or admin.php files and the bound parameters p, orderType & orderBy. The sql injection vulnerabilities can be exploited by remote attackers without user inter action & without privileged user account. Vulnerable File(s): [+] guestbook.php [+] admin.php Vulnerable Parameter(s): [+] orderType [+] p [+] orderBy 1.2 Multiple non persistent cross site scripting vulnerabilities are detected in the GuestBook Scripts PHP 1.5 Content Management System. The vulnerability allows remote attackers to hijack website customer, moderator or admin sessions with high required user inter action or local low privileged user account. The vulnerabilities are located in the admin.php file with the bound vulnerable search, p & ordertype parameters. Successful exploitation can result in account steal, phishing & client-side content request manipulation. Vulnerable File(s): [+] admin.php Vulnerable Parameter(s): [+] search [+] p [+] orderType Proof of Concept: ================= 1.1 The SQL Injection vulnerabilities can be exploited by remote attackers with and without privileged user account. User inter action is not required for exploitation.
