Detailsinfo

A vulnerability classified as critical was found in OpenEMR up to 8.4.x. This vulnerability affects the function SLEOB::slInvoiceNumber of the file src/Billing/SLEOB.php of the component ERA File Handler. The manipulation of the argument CLP01 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 in SLEOB::slInvoiceNumber() in src/Billing/SLEOB.php, which concatenates the CLP01 claim identifier from uploaded X12 835 ERA files into a query without escaping or parameter binding. Authenticated users with billing permissions, or a malicious payer whose ERA file a clerk uploads, can execute arbitrary SQL to read any table, including users_secure password hashes, and modify data.
