SQL injection vulnerability in modules/banners/click.php in the banners module for bcoos 1.0.10 allows remote attackers to execute arbitrary SQL commands via the bid parameter. NOTE: it was later reported that 1.0.13 is also affected.
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.
