CVE-2023-46227Network attack vector

Unauthenticated JDBC security bypass via tab characters

Published Oct 19, 2023 · Updated Sep 12, 2024

Deserialization flaw in Apache InLong Manager 1.4.0 through 1.8.0 allows remote attackers to alter JDBC security settings. The MySQLSinkDTO.filterSensitive method decodes a supplied MySQL JDBC URL but removes only literal spaces, so tab characters preserve attacker-selected autoDeserialize and local-file parameters instead of replacing them with safe values. No privileges or user interaction are required; Apache has not specified a downstream effect beyond bypassing those connection safeguards.
