Summary

Elastic Cloud Enterprise includes a default setting that enables the 'anonymous' user for all deployed clusters. While this user is designed with no permissions, it poses a risk as an attacker can exploit this configuration to gather sensitive information regarding the architecture and details of the cluster. This vulnerability could potentially lead to more severe security issues if left unaddressed, allowing unauthorized insights into the system's structure.

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.
