CVE-2020-7924

Medium
6.5/10

Summary

Usage of specific command line parameter in MongoDB Tools which was originally intended to just skip hostname checks, may result in MongoDB skipping all certificate validation. This may result in accepting invalid certificates. This issue affects github.com/mongodb/mongo-tools versions 4.1.11 through 4.2.10, 4.3.0 through 4.3.2 and 99.0.0 through 100.1.1 and github.com/mongodb/mongo-tools-common versions prior to 2.1.0 and 3.0.x prior to 4.0.4.

CWE-295 - Improper Certificate Validation

The authenticity component of a web system stems from the ability to validate “Digital certificates”, which (i) establish trust between two or more entities sharing data over a network; (ii) ensure data at rest and transit is secure from unauthorized access; and (iii) check the identity of the actors that interact with the system. An application with absent or ineffective certificate validation mechanisms allows malicious users, impersonating trusted hosts, to manipulate the communication path between the client and the host, resulting in unauthorized access to data and to the application’s internal environment, and potentially enabling man-in-the-middle attacks.
