How to Fix CVE-2023-49796

To remediate this vulnerability, upgrade all affected Mindsdb dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

mindsdb fixed: 23.11.4.1 
pip install mindsdb>=23.11.4.1
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

pip show mindsdb

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2023-49796, inspect your installed packages using pip:

pip show mindsdb

Analyze the terminal output to locate any version of Mindsdb in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 23.11.4.1), your application is affected.

Note: The pip show mindsdb command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-20: Improper Input Validation, where the product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. In Mindsdb, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact The put method in `mindsdb/mindsdb/api/http/namespaces/file.py` does not validate the user-controlled `name` value, which is used in a temporary file name, which is afterwards opened for writing on lines 122-125, which leads to path injection. This issue may lead to arbitrary file write. This vulnerability allows for writing files anywhere on the server that the filesystem permissions that the running server has access to. ### Patches Use mindsdb staging branch or v23.11.4.1 ### References * GHSL-2023-184 * See [CodeQL path injection prevention guidelines](https://codeql.github.com/codeql-query-help/python/py-path-injection/) and [OWASP guidelines](https://owasp.org/www-community/attacks/Path_Traversal).
