SQL injection vulnerability in the add_hit function in include/function.inc.php in Coppermine Photo Gallery (CPG) 1.4.8, when "Keep detailed hit statistics" is enabled, allows remote attackers to execute arbitrary SQL commands via the (1) referer and (2) user-agent HTTP headers.
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.
