Recommended response

  1. 1Check inventory. Check lockfiles and deployed manifests for Snowflake/net.snowflake:snowflake-jdbc, Snowflake/net.snowflake:snowflake-jdbc-fips, Snowflake/net.snowflake:snowflake-jdbc-thin.
  2. 2Review the reported fix. Update Snowflake/net.snowflake:snowflake-jdbc to 4.3.4; Snowflake/net.snowflake:snowflake-jdbc-fips to 4.3.4; Snowflake/net.snowflake:snowflake-jdbc-thin to 4.3.4; Snowflake/Snowflake JDBC Driver to 4.3.4; Snowflake/Snowflake JDBC Driver (FIPS) to 4.3.4; Snowflake/Snowflake JDBC Driver (Thin) to 4.3.4 if you use the affected versions. Test the change in a non-production environment first.

Sources and claim methodology

  • Source referencedocs.snowflake.com
Upstream source description

Improper input validation of the auto-configuration account identifier in Snowflake JDBC Driver versions 4.2.0 through 4.3.3 allowed a credential-bearing login request to be redirected to an attacker-selected HTTPS endpoint. An attacker able to control the account value could cause the driver to transmit a reusable login credential to a host of their choosing and replay it to obtain the privileges granted to that credential. Successful exploitation requires an application using jdbc:snowflake:auto with a connections.toml section that omits an explicit host and a lower-trust principal able to set the account value; ordinary JDBC URLs are unaffected. The fix is available in Snowflake JDBC Driver version 4.3.4, including the snowflake-jdbc-fips and snowflake-jdbc-thin. Users must manually upgrade.
