Detailsinfo

A vulnerability has been found in OpenEMR up to 8.4.x and classified as critical. Affected by this vulnerability is an unknown function of the file library/ajax/addlistitem.php. The manipulation of the argument option_id 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. The summary by CVE is:
