| عنوان | SourceCodester Contact Tracing System 1/11 Unrestricted Upload of File with Dangerous Type |
|---|
| الوصف | SourceCodester Contact Tracing System (commit be41d42) allows unauthenticated remote code execution. classes/Users.php exposes the f=save and f=delete actions with no authentication or authorization check. The save handler builds INSERT INTO users from raw POST keys (any row is an admin since the users table has no role column) and calls move_uploaded_file() on $_FILES['img'] into uploads/ with no extension, MIME, 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). The same endpoint also has a pre-auth SQL injection in the id parameter of the delete action. 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.
