SQL injection vulnerability in profile.php in FluxBB before 1.4.13 and 1.5.x before 1.5.7 allows remote attackers to execute arbitrary SQL commands via the req_new_email parameter.
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.
