CVE-2023-40694

Sensitive-data disclosure via locally readable ETCD logs

Published May 7, 2024 · Updated Aug 2, 2024

Sensitive-data exposure in IBM Watson CP4D Data Stores 4.0.0 through 4.8.4 allows local users to read information from ETCD logs. The ETCD logging path writes potentially sensitive information into locally readable log files; IBM has not identified the specific fields or code path. Local access to the OpenShift-hosted deployment is required, and the documented impact is limited to confidentiality.
