GitHub Vulnerability Alerts

GHSA-wfp9-vr4j-f49j

Versions of sequelize prior to 4.12.0 are vulnerable to NoSQL Injection. Query operators such as $gt are not properly sanitized and may allow an attacker to alter data queries, leading to NoSQL Injection.

Recommendation

Upgrade to version 4.12.0 or later

CVE-2019-10752

Affected versions of sequelize are vulnerable to SQL Injection. The function sequelize.json() incorrectly formatted sub paths for JSON queries, which allows attackers to inject SQL statements and execute arbitrary SQL queries if user input is passed to the query. Exploitation example:

return User.findAll({
  where: this.sequelize.json("data.id')) AS DECIMAL) = 1 DELETE YOLO INJECTIONS; -- ", 1)
});

Recommendation

If you are using sequelize 5.x, upgrade to version 5.15.1 or later.
If you are using sequelize 4.x, upgrade to version 4.44.3 or later.

GHSA-fw4p-36j9-rrj3

Versions of sequelize prior to 4.44.4 are vulnerable to Denial of Service (DoS). The SQLite dialect fails to catch a TypeError exception for the results variable. The results value may be undefined and trigger the error on a .map call. This may allow attackers to submit malicious input that forces the exception and crashes the Node process.

The following proof-of-concept crashes the Node process:

const Sequelize = require('sequelize');

const sequelize = new Sequelize({
	dialect: 'sqlite',
	storage: 'database.sqlite'
});

const TypeError = sequelize.define('TypeError', {
	name: Sequelize.STRING,
});

TypeError.sync({force: true}).then(() => {
	return TypeError.create({name: "SELECT tbl_name FROM sqlite_master"});
});

Recommendation

Upgrade to version 4.44.4 or later.

CVE-2023-25813

Impact

The SQL injection exploit is related to replacements. Here is such an example:

In the following query, some parameters are passed through replacements, and some are passed directly through the where option.

User.findAll({
  where: or(
    literal('soundex("firstName") = soundex(:firstName)'),
    { lastName: lastName },
  ),
  replacements: { firstName },
})

This is a very legitimate use case, but this query was vulnerable to SQL injection due to how Sequelize processed the query: Sequelize built a first query using the where option, then passed it over to sequelize.query which parsed the resulting SQL to inject all :replacements.

If the user passed values such as

{
  "firstName": "OR true; DROP TABLE users;",
  "lastName": ":firstName"
}

Sequelize would first generate this query:

SELECT * FROM users WHERE soundex("firstName") = soundex(:firstName) OR "lastName" = ':firstName'

Then would inject replacements in it, which resulted in this:

SELECT * FROM users WHERE soundex("firstName") = soundex('OR true; DROP TABLE users;') OR "lastName" = ''OR true; DROP TABLE users;''

As you can see this resulted in arbitrary user-provided SQL being executed.

Patches

The issue was fixed in Sequelize 6.19.1

Workarounds

Do not use the replacements and the where option in the same query if you are not using Sequelize >= 6.19.1

CVE-2023-22580

Due to improper input filtering in the sequelize js library, can malicious queries lead to sensitive information disclosure.

CVE-2023-22579

Impact

Providing an invalid value to the where option of a query caused Sequelize to ignore that option instead of throwing an error.

A finder call like the following did not throw an error:

User.findAll({
  where: new Date(),
});

As this option is typically used with plain javascript objects, be aware that this only happens at the top level of this option.

Patches

This issue has been patched in sequelize@6.28.1 & @sequelize/core@7.0.0.alpha-20

Snyk: https://security.snyk.io/vuln/SNYK-JS-SEQUELIZE-3324090

CVE-2023-22578

Impact

Sequelize 6.28.2 and prior has a dangerous feature where using parentheses in the attribute option would make Sequelize use the string as-is in the SQL

User.findAll({
  attributes: [
    ['count(id)', 'count']
  ]
});

Produced

SELECT count(id) AS "count" FROM "users"

Patches

This feature was deprecated in Sequelize 5, and using it prints a deprecation warning.

This issue has been patched in @sequelize/core@7.0.0.alpha-20 and sequelize@6.29.0.

In Sequelize 7, it now produces the following:

SELECT "count(id)" AS "count" FROM "users"

In Sequelize 6, it throws an error explaining that we had to introduce a breaking change, and requires the user to explicitly opt-in to either the Sequelize 7 behavior (always escape) or the Sequelize 5 behavior (inline attributes that include () without escaping). See https://github.com/sequelize/sequelize/pull/15710 for more information.

Mitigations

Do not use user-provided content to build your list or attributes. If you do, make sure that attribute in question actually exists on your model by checking that it exists in the rawAttributes property of your model first.

Micro-Learning Topic: NoSQL injection (Detected by phrase)

What is this? (2min video)

NoSQL is a variation of data-management technologies, grouped arbitrarily under this name, that really means “non-relational database systems”. This includes graph databases (Cassandra), document databases (MongoDB), key-value stores (Amazon DynamoDB) amongst others.

NoSQL injection happens when an application uses input to build a query or statement without proper filtering or encoding. This may allow an attacker to modify the instruction that is sent to the non-relational database system by supplying specially constructed values, resulting in unauthorised retrieval or modification of data records.

Micro-Learning Topic: SQL injection (Detected by phrase)

What is this? (2min video)

This is probably one of the two most exploited vulnerabilities in web applications and has led to a number of high profile company breaches. It occurs when an application fails to sanitize or validate input before using it to dynamically construct a statement. An attacker that exploits this vulnerability will be able to gain access to the underlying database and view or modify data without permission.

Micro-Learning Topic: Denial of service (Detected by phrase)

The Denial of Service (DoS) attack is focused on making a resource (site, application, server) unavailable for the purpose it was designed. There are many ways to make a service unavailable for legitimate users by manipulating network packets, programming, logical, or resources handling vulnerabilities, among others.

What is this? (2min video)

This is probably one of the two most exploited vulnerabilities in web applications and has led to a number of high profile company breaches. It occurs when an application fails to sanitize or validate input before using it to dynamically construct a statement. An attacker that exploits this vulnerability will be able to gain access to the underlying database and view or modify data without permission.

Micro-Learning Topic: Denial of service (Detected by phrase)

Matched on "Denial of Service"

The Denial of Service (DoS) attack is focused on making a resource (site, application, server) unavailable for the purpose it was designed. There are many ways to make a service unavailable for legitimate users by manipulating network packets, programming, logical, or resources handling vulnerabilities, among others.

What is this? (2min video)

NoSQL is a variation of data-management technologies, grouped arbitrarily under this name, that really means “non-relational database systems”. This includes graph databases (Cassandra), document databases (MongoDB), key-value stores (Amazon DynamoDB) amongst others.

Micro-Learning Topic: Information disclosure (Detected by phrase)

Matched on "information disclosure"

Many web applications and APIs do not properly protect sensitive data, such as financial, healthcare, and PII. Attackers may steal or modify such weakly protected data to conduct credit card fraud, identity theft, or other crimes. Sensitive data may be compromised without extra protection, such as encryption at rest or in transit, and requires special precautions when exchanged with the browser.
