SQL injection vulnerability in the getCsvFile function in the Mage_Adminhtml_Block_Widget_Grid class in Magento Community Edition (CE) 1.9.1.0 and Enterprise Edition (EE) 1.14.1.0 allows remote administrators to execute arbitrary SQL commands via the popularity[field_expr] parameter when the popularity[from] or popularity[to] parameter is set.
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.
