Description

The Filebird Plugin 4.7.3 introduced a SQL injection vulnerability as it is making SQL queries without escaping user input data from a HTTP post request. This is a major vulnerability as the user input is not escaped and passed directly to the get_col function and it allows SQL injection. The Rest API endpoint which invokes this function also does not have any required permissions/authentication and can be accessed by an anonymous user.

• CWE-89Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')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.
