Detailsinfo

A vulnerability was found in OpenEMR up to 8.4.x and classified as critical. Affected by this issue is an unknown code block of the file edit_layout.php of the component History Layout. 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. CVE summarizes:

OpenEMR before 8.5.0 contains a stored SQL injection vulnerability in which History layout field identifiers saved through edit_layout.php, including HIS fields and LBF source-H fields, are placed unvalidated into an INSERT statement for patients without a history_data row. Users with admin/super and patients/med write access can trigger history_save.php or LBF saves to execute SQL functions like SLEEP, tying up database workers or accessing data beyond their privileges.
