Multiple SQL injection vulnerabilities in Gnew 2013.1 allow remote attackers to execute arbitrary SQL commands via the (1) news_id parameter to news/send.php, (2) thread_id parameter to posts/edit.php, or (3) user_email parameter to users/password.php or (4) users/register.php. NOTE: these issues were SPLIT from CVE-2013-5640 due to differences in researchers and disclosure dates.
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.
