Detailsinfo

A vulnerability was found in OpenEMR up to 8.4.x. It has been classified as critical. Affected is the function fetchFormValues of the component Savedata Action. The manipulation 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. 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. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

OpenEMR before 8.5.0 contains a second-order sql injection vulnerability that allows authenticated Carecoordination users to store malicious C-CDA field identifiers through the savedata action. Attackers can inject SQL into the IN clause built by fetchFormValues() during C-CDA generation to extract password hashes, portal reset values, and patient records.
