Summary

Neo4j versions prior to 3.4.18, when the shell server is enabled, expose a Remote Method Invocation (RMI) service that is vulnerable to arbitrary deserialization of Java objects. This flaw allows attackers to exploit dependencies linked to insecure gadget chains, leading to potential remote code execution. Proper security measures and updates are essential to mitigate this risk.

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
