Multiple SQL injection vulnerabilities in the InterJoomla ArtForms (com_artforms) component 2.1b7.2 RC2 for Joomla! allow remote attackers to execute arbitrary SQL commands via the viewform parameter in a (1) ferforms or (2) tferforms action to index.php, and the (3) id parameter in a vferforms action to index.php.
Improper Neutralization of Special Elements used in an SQL Command 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.
