Description

OpenEMR is a free and open source electronic health records and medical practice management application. Prior to version 8.0.0.3, the PostCalendar module contains a blind SQL injection vulnerability in the `categoriesUpdate` administrative function. The `dels` POST parameter is read via `pnVarCleanFromInput()`, which only strips HTML tags and performs no SQL escaping. The value is then interpolated directly into a raw SQL `DELETE` statement that is executed unsanitized via Doctrine DBAL's `executeStatement()`. Version 8.0.0.3 patches the issue.
