Affected: openemr

OpenEMR before 8.3.0 contains an SQL injection vulnerability in the Fee Sheet drug-inventory lookup (DrugSalesService::sellDrug) that interpolates the prod[N][warehouse] POST field into an ORDER BY clause. Low-privileged authenticated users can submit Fee Sheet product lines with constant subqueries to run a time-based blind oracle, extracting patient data and users_secure bcrypt hashes.
