A vulnerability has been found in SourceCodester Clinics Patient Management System 2.0 and classified as critical. Affected by this vulnerability is an unknown functionality of the file /pms/index.php of the component Login Page. The manipulation of the argument user_name with the input admin' or '1'='1 leads to sql injection. The attack can be launched remotely. The exploit has been disclosed to the public and may be used.
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.
