AI-Generated

MongoDB is vulnerable to a flaw that allows authenticated users with readWrite privileges to crash the mongod server by using an incompatible WiredTiger storage configuration during collection creation. This type confusion in the storage engine can lead to corrupted memory interpretation when accessing the affected collection, resulting in a server crash that persists across restarts and necessitates manual remediation. Organizations using MongoDB, particularly those with user access management in place, should prioritize addressing this vulnerability to prevent potential service disruptions.

Original NVD Description

A security issue was discovered in MongoDB where an authenticated user with readWrite privileges could crash the mongod server process. By specifying a custom WiredTiger storage configuration option with an incompatible value during collection creation, a user could cause a type confusion in the storage engine layer. When documents were subsequently read from the misconfigured collection, the resulting mismatch in expected data format led to corrupted memory interpretation and a server crash. The crafted collection configuration persists across restarts, requiring manual operator intervention to remediate.
