Detailsinfo A vulnerability was found in OpenEMR. It has been classified as critical. Affected is the function pnVarCleanFromInput of the component PostCalendar Module. The manipulation of the argument dels with an unknown input leads to a sql injection vulnerability. CWE is classifying the issue as CWE-89. The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes: 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.
