The busid parameter received via HTTP POST is concatenated directly into a MySQL query (select * from bus_info where id=$busid) without sanitization, escaping, or parameterization, and in a numeric (unquoted) context. A remote, unauthenticated attacker can inject arbitrary SQL — for example a UNION-based payload such as busid=-1 UNION SELECT 1,2,3,4,5,6 — to read arbitrary data from the bus_service database.
