CVE-2023-34231Network attack vector

Remote code execution via unvalidated SSO URL

Published Jun 8, 2023 · Updated Jan 6, 2025

Command injection in Snowflake Go Snowflake Driver before 1.6.19 allows remote attackers to execute commands via SSO browser URL authentication. The SSO browser authentication path accepted a connection URL without validating its scheme or encoding command-sensitive characters; the fix adds URL validation and query escaping. Exploitation requires a malicious public server and a user tricked into opening the crafted connection URL, after which commands execute on the user's local machine.
