SQL Injection in sequelize
Affected versions of sequelize cast arrays to strings and fail to properly escape the resulting SQL statement, resulting in a SQL injection vulnerability.
Proof of Concept
In Postgres, SQLite, and Microsoft SQL Server there is an issue where arrays are treated as strings and improperly escaped.
Example Query:
database.query('SELECT * FROM TestTable WHERE Name IN (:names)', {
replacements: {
names: directCopyOfUserInput
}
});If the user inputs the value of :names as:
["test", "'); DELETE TestTable WHERE Id = 1 --')"]The resulting SQL statement will be:
SELECT Id FROM Table WHERE Name IN ('test', '\'); DELETE TestTable WHERE Id = 1 --')As the backslash has no special meaning in PostgreSQL, MSSQL, or SQLite, the statement will delete the record in TestTable with an Id of 1.
Recommendation
Update to version 3.20.0 or later.
