| Título | Code-projects Student File Management System v1.0 Stored XSS vulnerability |
|---|
| Descripción | A storage-type XSS vulnerability was found in the "update_user.php" file of the "Student File Management System" project. Root Cause Because update_user.php does not escape, clean or parameterize the POST request data submitted by the user, when the attacker submits a malicious Payload in the firstname, lastname field (for example,"<img src=x onerror=alert(1)>"), the code does not block it and permanently stores it in the "user" table of the database. When “user.php” reads the malicious firstname, lastname data in the database, and “echo $fetch['firstname']、echo $fetch['lastname']” to an HTML page as-is, the browser will <script>treat the HTML tag and execute its content. Immediate corrective actions are essential to safeguard system security and uphold data integrity. |
