CyberRota Analysis

AI-Generated

MongoDB Schema Manager and the MongoDB Atlas SQL ODBC Driver are vulnerable due to inadequate validation of the authorization and token endpoints from an OIDC issuer's discovery document. This flaw could allow an attacker to exploit a user's connection to an uncontrolled MongoDB deployment, potentially leading to credential exposure or remote code execution in the user's context. Organizations using these MongoDB products, especially those implementing MONGODB-OIDC authentication, should prioritize remediation to mitigate these risks.

Original NVD Description

MongoDB Schema Manager and MongoDB Atlas SQL ODBC Driver do not validate the scheme of the authorization and token endpoints returned by an OIDC issuer's discovery document. A user induced to connect to an uncontrolled MongoDB deployment using MONGODB-OIDC authentication may have an uncontrolled URI dispatched to their operating system's default protocol handler, potentially exposing credentials or, under certain conditions, resulting in code execution in the user's context.
