DescriptionCVE.org

A vulnerability was detected in imvks786 student_management_system up to 9599b560ad3c3b83e75d328b76bedcd489ef1f46. Affected by this issue is some unknown functionality of the file /add.php. The manipulation of the argument name/address/fname results in cross site scripting. It is possible to launch the attack remotely. The exploit is now public and may 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.

AnalysisAI

Cross-site scripting in imvks786/student_management_system allows a low-privileged remote attacker to inject malicious scripts via the name, address, or fname parameters in /add.php. The payload executes in a victim's browser when the affected page is viewed, enabling session hijacking, credential theft, or UI redress attacks against other users of the application. A public exploit is available via a GitHub issue report; the vendor has not responded to the coordinated disclosure.

Technical ContextAI

The affected application is a PHP-based student management system hosted on GitHub by imvks786, identified by CPE cpe:2.3:a:imvks786:student_management_system:*:*:*:*:*:*:*:*. The vulnerability is classified as CWE-79 (Improper Neutralization of Input During Web Page Generation), meaning user-supplied data in the name, address, and fname form fields of /add.php is rendered back into the HTML DOM without adequate output encoding or sanitization. This is a fundamental PHP output handling deficiency - the application likely echoes raw POST or GET parameters directly into HTML, allowing script injection. The project uses a rolling release model with no versioned tags, making patch tracking via CPE version fields impractical.

RemediationAI

No vendor-released patch has been identified at time of analysis - the maintainer has not responded to the disclosure. The primary fix requires implementing output encoding on all user-supplied values echoed into HTML in /add.php, using PHP's htmlspecialchars() or htmlentities() with ENT_QUOTES and the correct charset before rendering name, address, and fname fields. As a compensating control, deploying a web application firewall (WAF) rule to detect and block common XSS payloads (e.g., script tags, javascript: URI schemes) in those specific parameters can reduce exploitation risk with minimal side effects. Additionally, restricting access to /add.php to only necessary authenticated roles reduces the attacker pool, given that PR:L requires a valid account. If the application is internet-facing and not actively maintained, consider taking it offline or placing it behind VPN/IP allowlisting.
