Summary

MongoDB Database Tools from version 3.1.4 before 100.20.1 are affected. The mongofiles get_id command uses a filename stored in the database as its output destination when --local is not specified, which is an external control of file name or path (CWE-73). A user who can modify GridFS file metadata can set the stored filename to '-', so a later retrieval by a higher-privileged operator writes the file contents to standard output. If that output is captured in a location the attacker can access, GridFS content the attacker cannot read directly may be disclosed, and exploitation requires that operator to retrieve the file without an explicit local destination.

Description from the CNA

MongoDB Database Tools mongofiles uses a database-stored GridFS filename as the output destination for get_id when --local is not specified. A user who can modify the file metadata can set the stored filename to '-', causing a later authorized retrieval to write the file contents to standard output instead of a local file. If standard output is captured in a location accessible to that user, this may disclose GridFS content the user cannot read directly. Exploitation requires a higher-privileged operator to retrieve the affected file without an explicit local destination and attacker access to the captured output. This issue affects MongoDB Database Tools from version 3.1.4 through versions before 100.20.1.
