An insecure direct object reference (IDOR) in the component /assets/stafffiles of OS4ED openSIS v7.0 to v9.1 allows unauthenticated attackers to access files uploaded by staff members.
OS4ED openSIS v7.0 to v9.1 was discovered to contain a SQL injection vulnerability via the table parameter at /attendance/AttendanceCodes.php. The remote, authenticated attacker requires the admin role to successfully exploit this vulnerability.
OpenSIS Community Edition through 7.6 is affected by incorrect access controls for the file ResetUserInfo.php that allow an unauthenticated attacker to change the password of arbitrary users.
