What is CVE-2024-10553?

A vulnerability in the h2o-3 REST API allows unauthenticated remote attackers to execute arbitrary code by exploiting deserialization of untrusted data. This occurs specifically in the POST /99/ImportSQLTable and POST /3/SaveToHiveTable endpoints, where user-controlled JDBC URLs are improperly passed to DriverManager.getConnection. If a MySQL or PostgreSQL driver is present in the classpath, it can lead to serious security implications. This issue has been addressed in h2o-3 version 3.47.0, and users are advised to upgrade to mitigate potential threats.
