SQL injection vulnerability in linking.page.php in Automated Link Exchange Portal allows remote attackers to execute arbitrary SQL commands via the cat_id parameter. NOTE: linking.page.php is commonly renamed to link.php, links.php, etc.
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.
