A vulnerability was found in SourceCodester Simple Student Attendance System 1.0 and classified as critical. Affected by this issue is the function delete_class/delete_student of the file /ajax-api.php of the component List of Classes Page. The manipulation of the argument id with the input 1337'+or+1=1;--+ leads to sql injection. The attack may be launched remotely. The exploit has been disclosed to the public and may be used. VDB-254858 is the identifier assigned to this vulnerability.
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.
