CVE-2023-2042Network attack vector

Authenticated unspecified impact via JDBC deserialization

Published Apr 14, 2023 · Updated Sep 16, 2024

Deserialization in DataGear 4.0 through 4.7.0 and 5.0 through 5.1.0 allows remote authenticated users to cause unspecified impact. The JDBC Server Handler processes attacker-controlled serialized data, but published material does not identify the parsing method or omitted validation. A valid low-privilege session is required, and no concrete read, write, execution, or service-interruption outcome is documented.
