The vulnerability was found Moodle which exists due to insufficient sanitization of user-supplied data in external Wiki method for listing pages. A remote attacker can send a specially crafted request to the affected application and execute limited SQL commands within the application database.
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.
