CVE-2021-20331
4.2 · MEDIUMOverview
CVE-2021-20331 is a medium-severity vulnerability affecting mongodb c\#_driver. It was published on May 13, 2021 and has a CVSS 3.1 base score of 4.2 (MEDIUM).
This vulnerability has a CVSS 3.1 base score of 4.2, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.
Technical Description
Specific versions of the MongoDB C# Driver may erroneously publish events containing authentication-related data to a command listener configured by an application. The published events may contain security-sensitive data when commands such as "saslStart", "saslContinue", "isMaster", "createUser", and "updateUser" are executed. Without due care, an application may inadvertently expose this authenticated-related information, e.g., by writing it to a log file. This issue only arises if an application enables the command listener feature (this is not enabled by default). This issue affects the MongoDB C# Driver v2.12 versions prior to and including 2.12.1.
Remediation
Check the references section for vendor advisories and patches from mongodb. Update c\#_driver to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.

| Vendor | Product | Versions | Status |
