SQL injection vulnerability in sub_votepic.php in the Datsogallery (com_datsogallery) module 1.6 for Joomla! allows remote attackers to execute arbitrary SQL commands via the User-Agent HTTP header.
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.
