| Title | SourceCodester E-Learning System 0cfc03f Unrestricted Upload of File with Dangerous Type |
|---|
| Description | SourceCodester E-Learning System (php-elearning-system, commit 0cfc03f) allows unauthenticated remote code execution. The action dispatcher at the bottom of classes/Users.php (f=save, fsave, ssave, delete) performs no authentication or authorization check. save_users() interpolates raw POSTintoINSERTINTOusers(anycreatedrowlogsinasadminsincetheuserstablehasnorolecolumn)andmoveuploadedfile()stores_FILES['img'] under uploads/ with no extension or content validation. An unauthenticated attacker creates an admin account, uploads a PHP web shell, and executes OS commands; live reproduction returned uid=0(root). CVSS 3.1 score 9.8 Critical, vector CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H. Discovered by Santhosh Kumar, TraceX Labs.
