Multiple SQL injection vulnerabilities in recover.php in Pligg CMS 2.0.1 and earlier allow remote attackers to execute arbitrary SQL commands via the (1) id or (2) n parameter.
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.
