Multiple SQL injection vulnerabilities in NetArt Media Blog System 1.5 allow remote attackers to execute arbitrary SQL commands via the (1) cat parameter to index.php and the (2) note parameter to blog.php.
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.
