Multiple SQL injection vulnerabilities in register.php in Geodesic Solutions GeoCore MAX 7.3.3 (formerly GeoClassifieds and GeoAuctions) allow remote attackers to execute arbitrary SQL commands via the (1) c[password] or (2) c[username] parameter. NOTE: the b parameter to index.php vector is already covered by CVE-2006-3823.
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.
