Multiple SQL injection vulnerabilities in yBlog 0.2.2.2 allow remote attackers to execute arbitrary SQL commands via (1) the q parameter to search.php, or the n parameter to (2) user.php or (3) uss.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.
