CVE-2020-1963Network attack vector

Server file read and write via H2 rights

Published Jun 3, 2020 · Updated Aug 4, 2024

Incorrect authorization in Apache Ignite 2.8.0 and earlier allows remote attackers to read or write server files through SQL queries. User SQL connections receive H2 administrator rights, exposing privileged H2 file functions instead of restricting them. An attacker must reach an Ignite SQL endpoint; successful queries affect files accessible to the Ignite process without interrupting the service.
