RosarioSIS before 12.9 contains a sql injection vulnerability that allows authenticated non-student users, including parents, to inject SQL via the unquoted period id parameter in StudentSummary.php. Attackers can supply payloads without single quotes into IN() clauses to extract administrator password hashes and student records through time-based queries or modify data via stacked statements.

RosarioSIS before 12.9 contains an improper authorization vulnerability that allows school-scoped administrators to assign fees and payments to students of other schools via MassAssignFees.php and MassAssignPayments.php. Attackers can substitute foreign student IDs in the student[] POST array of a modfunc=save request to alter other schools' student billing balances, breaking school isolation.

Authenticated teachers can write records for students outside their assigned course period by providing arbitrary student IDs. This is possible by modifying the `st arr`, `values`, or `attendance` POST arrays within the following endpoints: 'MakeReferral.php', 'EnterEligibility.php', 'InputFinalGrades.php', and 'TakeAttendance.php'. This allows the creation of referrals, eligibility codes, attendance records, and final grades for any student in the school.
