# Elastic Cloud Enterprise: leftover certificate rotation data exposes platform credentials and keys

After the Elastic Cloud Enterprise certificate rotation procedure runs, retained files contain platform credentials and certificate authority private keys that lower-privileged components can read. An attacker who controls any host in the installation can use those secrets to take over the ECE control plane and the deployments it manages.

_Summary, check and fix written by a model from the sources; labelled as such._

## From the sources

Insertion of Sensitive Information into Externally-Accessible File or Directory (CWE-538) in Elastic Cloud Enterprise (ECE) can lead to privilege escalation via Retrieve Embedded Sensitive Data (CAPEC-37). After the ECE certificate rotation procedure runs, data that it retains contains platform credentials and certificate authority private keys, and lower-privileged platform components can read this data. An attacker who controls any host in the installation can use this data to get full control of the ECE control plane and of the deployments that it manages.
