webchess v1.0 was discovered to contain a SQL injection vulnerability via the $playerID parameter at mainmenu.php. NOTE: this is disputed by a third party who indicates that the playerID is a session variable controlled by the server, and thus cannot be used for exploitation.
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.
