CVSS: 8.1EPSS: 0%CPEs: 3EXPL: 2CVE-2021-21422 – XSS Vulnerability in mongo-express
https://notcve.org/view.php?id=CVE-2021-21422
mongo-express is a web-based MongoDB admin interface, written with Node.js and express. 1: As mentioned in this issue: https://github.com/mongo-express/mongo-express/issues/577, when the content of a cell grows larger than supported size, clicking on a row will show full document unescaped, however this needs admin interaction on cell. 2: Data cells identified as media will be rendered as media, without being sanitized. Example of different renders: image, audio, video, etc. As an example of type 1 attack, an unauthorized user who only can send a large amount of data in a field of a document may use a payload with embedded javascript. This could send an export of a collection to the attacker without even an admin knowing. Other types of attacks such as dropping a database\collection are possible. mongo-express es una interfaz de administración de MongoDB basada en la web, escrita con Node.js y express. 1: Como se menciona en este tema: https://github.com/mongo-express/mongo-express/issues/577, cuando el contenido de una celda crece más que el tamaño soportado, al hacer clic en una fila se mostrará el documento completo sin escapar, sin embargo esto necesita la interacción del administrador en la celda. 2: Las celdas de datos identificadas como medios de comunicación se renderizarán como medios de comunicación, sin ser saneados. • https://github.com/mongo-express/mongo-express/commit/f5e0d4931f856f032f22664b5e5901d5950cfd4b https://github.com/mongo-express/mongo-express/issues/577 https://github.com/mongo-express/mongo-express/security/advisories/GHSA-7p8h-86p5-wv3p • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
CVSS: 8.6EPSS: 5%CPEs: 1EXPL: 2CVE-2021-32820 – File disclosure in Express Handlebars
https://notcve.org/view.php?id=CVE-2021-32820
Express-handlebars is a Handlebars view engine for Express. Express-handlebars mixes pure template data with engine configuration options through the Express render API. More specifically, the layout parameter may trigger file disclosure vulnerabilities in downstream applications. This potential vulnerability is somewhat restricted in that only files with existing extentions (i.e. file.extension) can be included, files that lack an extension will have .handlebars appended to them. For complete details refer to the referenced GHSL-2021-018 report. • https://github.com/express-handlebars/express-handlebars/blob/78c47a235c4ad7bc2674bddd8ec2721567ed8c72/README.md#danger- https://github.com/express-handlebars/express-handlebars/commit/78c47a235c4ad7bc2674bddd8ec2721567ed8c72 https://github.com/express-handlebars/express-handlebars/pull/163 https://securitylab.github.com/advisories/GHSL-2021-018-express-handlebars https://www.npmjs.com/package/express-handlebars • CWE-94: Improper Control of Generation of Code ('Code Injection') CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
