Detailsinfo

A vulnerability has been found in OpenEMR up to 8.4.9 and classified as critical. This vulnerability affects an unknown functionality of the component CCR revandapprove controller. The manipulation of the argument patient_data with an unknown input leads to a sql injection vulnerability. The CWE definition for the vulnerability is 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. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

OpenEMR before 8.5.0 contains an sql injection vulnerability that allows any authenticated core user to inject SQL by supplying crafted patient_data field names to the CCR revandapprove controller. Attackers can embed scalar subqueries in the UPDATE patient_data SET clause to read staff password hashes and portal reset values, alter arbitrary patient demographics, and take over patient-portal accounts.
