Privilege escalation in Kushan2k student-management-system allows authenticated remote attackers to grant themselves administrator rights by manipulating the `isadmin` parameter in the Profile Update Endpoint. The `edit-admin` function in `controllers/AdminController.php` performs no server-side authorization check on this parameter, enabling any low-privileged account holder to self-elevate to admin. A publicly available exploit exists per VulDB and a GitHub issue disclosure; the vendor has not yet responded, and no patch has been released under the rolling-release model.
SQL injection in the `getStatus` function of `controllers/GradeController.php` within Kushan2k's student-management-system exposes the Certificate Verification Endpoint to database manipulation by low-privileged remote attackers via the `nic` parameter. A publicly available exploit (proof-of-concept via GitHub issue) lowers the practical bar for abuse despite the CVSS 4.0 base score of 2.1. No patch has been released, and the maintainer has not responded to responsible disclosure, leaving all deployments through commit f16a4ceaddd6729c4b306ed4641cda3176c1ef2a unprotected.
Unrestricted file upload in Kushan2k's student-management-system exposes the registration endpoint to unauthenticated remote attackers who can upload arbitrary files - including PHP webshells - by manipulating the `stimg` argument in `service/RegisterService.php`. The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N) confirms no authentication, no complexity, and no user interaction are required, making this trivially exploitable by any network-reachable attacker. Publicly available exploit code exists (E:P confirmed), and the vendor has not responded to responsible disclosure as of analysis time, leaving all installations unpatched.
