CyberRota Analysis

AI-Generated

Budibase versions prior to 3.40.1 are vulnerable due to improper handling of user-supplied file paths in the MongoDB integration, allowing builders to exploit the system by submitting absolute paths. This could lead to information disclosure, as attackers can determine the existence and readability of files on the shared server. Organizations using Budibase, particularly those integrating with MongoDB or Oracle, should prioritize upgrading to version 3.40.1 to mitigate this risk.

Original NVD Description

Budibase is an open-source low-code platform. Prior to 3.40.1, packages/server/src/integrations/mongodb.ts passed builder-controlled tlsCertificateKeyFile and tlsCAFile values directly to MongoClient on Budibase Cloud. A builder could submit absolute server paths through /api/datasources/verify and distinguish readable existing files from missing files by comparing the driver error, exposing a filesystem existence and readability oracle on the shared server. This issue is fixed in version 3.40.1.
