Multiple SQL injection vulnerabilities in Sticky Notes before 0.2.27052012.5 allow remote attackers to execute arbitrary SQL commands via the (1) paste id in admin/modules/mod_pastes.php or (2) show.php, (3) user id to admin/modules/mod_users.php, (4) project to list.php, or (5) session id to show.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.
