IwebNegar is prone to an SQL-injection vulnerability because the application fails to properly sanitize user-supplied input before using it in an SQL query. 

A successful exploit could allow an attacker to compromise the application, access or modify data, or exploit vulnerabilities in the underlying database implementation.

IwebNegar 1.1 is reportedly affected by this issue; other versions may be affected as well.
