CVE-2023-50731

Summary

CVE-2023-50731 is a critical vulnerability that affects MindsDB, a SQL Server for artificial intelligence. Specifically, versions prior to 23.11.4.1 are vulnerable. The vulnerability lies in the "put" method in "mindsdb/mindsdb/api/http/namespaces/file.py", which fails to validate the user-controlled name value used in a temporary file name. This allows for path injection, enabling an attacker to write arbitrary file contents outside of the intended directory. The temporary directory is deleted later in the method, but since the potentially dangerous files are written outside of it, they are not removed. The affected products include various versions of MindsDB (qsvSqS, qsvSo3, qsvSoz, etc.). The potential danger this vulnerability poses to an organization is significant as it allows for unauthorized access and manipulation of files on the server hosting MindsDB. To remediate this vulnerability, organizations should update their MindsDB installation to version 23.11.4.1 or higher where the issue has been addressed.
