Detailsinfo

A vulnerability was found in OpenEMR up to 8.4.x and classified as critical. This issue affects some unknown functionality of the component Report/Portal/Transaction/Immunization. The manipulation with an unknown input leads to a sql injection vulnerability. Using CWE to declare the problem leads to 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. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

OpenEMR before 8.5.0 contains multiple missing authorization and SQL injection defects across report, portal, transaction, and immunization components.
