PHPads 2.0 SQL Injection via click.php3 bannerID

PHPads 2.0 contains an SQL injection vulnerability that allows unauthenticated attackers to execute arbitrary SQL queries by injecting malicious code through the bannerID parameter in click.php3. Attackers can submit crafted bannerID values using SQL comment syntax and functions like extractvalue to extract sensitive database information such as the current database name.

PHPads 2.0 allows remote attackers to obtain sensitive information via a direct request to a .php file, which reveals the installation path in an error message, as demonstrated by ads.inc.php.
