facileManager is a modular suite of web apps built with the sysadmin in mind. In versions 4.5.0 and earlier, the $_REQUEST global array was unsafely called inside an extract() function in admin-logs.php. The PHP file fm-init.php prevents arbitrary manipulation of $_SESSION via the GET/POST parameters. However, it does not prevent manipulation of any other sensitive variables such as $search_sql. Knowing this, an authenticated user with privileges to view site logs can manipulate the search_sql variable by appending a GET parameter search_sql in the URL. The information above means that the checks and SQL injection prevention attempts were rendered unusable.
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.
