SQL injection vulnerability in the acctexp (com_acctexp) component 0.12.x and earlier for Joomla! allows remote attackers to execute arbitrary SQL commands via the usage parameter in a subscribe action to index.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.
