Description
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.
