CVE-2026-5643 Details
Description
A vulnerability was identified in Cyber-III Student-Management-System up to 1a938fa61e9f735078e9b291d2e6215b4942af3f. This impacts an unknown function of the file /admin/Add%20notice/notice.php of the component Admin Add Endpoint. Such manipulation of the argument $_SERVER['PHP_SELF'] leads to cross site scripting. It is possible to launch the attack remotely. The exploit is publicly available and might be used. This product takes the approach of rolling releases to provide continious delivery. Therefore, version details for affected and updated releases are not available. The project was informed of the problem early through an issue report but has not responded yet.
A reflected cross-site scripting (XSS) vulnerability exists in Cyber-III Student-Management-System versions prior to 1a938fa61e9f735078e9b291d2e6215b4942af3f. The issue is located in the Admin Add Endpoint component, specifically within the file '/admin/Add notice/notice.php'. The vulnerability arises because the script uses the unsanitized '$_SERVER["PHP_SELF"]' variable as the form action, allowing attackers to inject arbitrary JavaScript through a crafted URL. This vulnerability can be exploited remotely, requires authentication, and involves user interaction.
To address this vulnerability, sanitize the '$_SERVER["PHP_SELF"]' variable before using it in the form action. This can be done by encoding the output with 'htmlspecialchars()' to prevent script injection. Alternatively, use a static URL value instead of a dynamic one.
