CVE-2023-50731: MindsDB has arbitrary file write in file.py

CriticalCVSS 9.1 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 36/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.98% (FIRST EPSS); higher than 62.7% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: mindsdb (PyPI) 23.11.4.1.

Low priority for now. Upgrade to mindsdb (PyPI) 23.11.4.1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

MindsDB is a SQL Server for artificial intelligence. Prior to version 23.11.4.1, 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. Later in the method, the temporary directory is deleted on line 151, but since we can write outside of the directory using the path injection vulnerability, the potentially dangerous file is not deleted. Arbitrary file contents can be written due to `f.write(chunk)` on line 125. Mindsdb does check later on line 149 in the `save_file` method in `file-controller.py` which calls the `_handle_source` method in `file_handler.py` if a file is of one of the types `csv`, `json`, `parquet`, `xls`, or `xlsx`. However, since the check happens after the file has already been written, the files will still exist (and will not be removed due to the path injection described earlier), just the `_handle_source` method will return an error. The same user-controlled source source is used also in another path injection sink on line 138. This leads to another path injection, which allows an attacker to delete any `zip` or `tar.gz` files on the server.
