CyberRota Analysis

AI-Generated

The MongoDB Rust Driver is vulnerable due to its failure to properly neutralize special characters in user-supplied target identifiers, potentially allowing an attacker to manipulate these identifiers. This could lead to unauthorized write operations on unintended data within the same deployment, compromising data integrity and confidentiality. Organizations using the MongoDB Rust Driver should prioritize this vulnerability to prevent potential data breaches and ensure proper access controls are maintained.

Original NVD Description

The MongoDB Rust Driver does not neutralize special characters in a caller-supplied target identifier before embedding it in the request it sends to the server. An actor able to influence that identifier in an application using the driver may cause write operations to be applied to an unintended target within the same deployment using the application's own credentials. This may result in unauthorized modification of data belonging to another logical boundary enforced by the application.
