CVE-2023-31847Public exploitNetwork attack vector

Authenticated file disclosure via malicious MySQL server

Published May 17, 2023 · Updated Jan 22, 2025

Arbitrary file read in Davinci 0.3.0-rc allows remote authenticated users to read server-side files through a crafted MySQL data source. The MySQL JDBC connection leaves local-file and URL loading permitted, allowing an attacker-controlled server to request a local path from the Davinci host. A valid login and access to configure and test a MySQL data source are required; exposure is limited to files readable by the Davinci process.
