CVE-2024-45384Network attack vector

Session cookie manipulation via decryption error oracle

Published Sep 17, 2024 · Updated Mar 14, 2025

Padding oracle in Apache Druid 0.18.0 through 30.0.0 allows remote attackers to manipulate pac4j session cookies. CryptoService.decrypt passed Cipher.doFinal failures through RuntimeException, exposing distinguishable responses for modified ciphertext. Exposure requires the optional, disabled-by-default druid-pac4j authenticator on a Router; Apache reports no known meaningful exploitation.
