Multiple SQL injection vulnerabilities in stats/index.php in chCounter 3.1.3 allow remote attackers to execute arbitrary SQL commands via (1) the login_name parameter (aka the username field) or (2) the login_pw parameter (aka the password field).
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.
