Deserialization of Untrusted Data in Neo4j

Quick fix

GHSA-pc4w-8v5j-29w9 — org.neo4j:neo4j: upgrade to the fixed version with the command below.

# pom.xml: bump <version>3.5.0</version> for org.neo4j:neo4j

Details

Neo4j through 3.4.18 (with the shell server enabled) exposes an RMI service that arbitrarily deserializes Java objects, e.g., through setSessionVariable. An attacker can abuse this for remote code execution because there are dependencies with exploitable gadget chains.
