AI Insight
LLM-synthesized narrative grounded in this CVE's description and references.
IBM Cloud Private 3.1.1 exposes unencrypted intra-service communications, allowing a local admin to intercept sensitive data.
Vulnerability
IBM Cloud Private 3.1.1 uses unencrypted HTTP for intra-service communications to the Identity and Access Management (IAM) Policy Decision Point (PDP) service. This exposes highly sensitive data transmitted between components within the cluster [1].
Exploitation
An attacker with local administrator privileges on the cluster can intercept network traffic between services. No additional network position or user interaction is required; the attacker can monitor the unencrypted HTTP channels to capture data as it flows between nodes and services [1].
Impact
Successful exploitation results in the disclosure of highly sensitive data. The confidentiality impact is high, while integrity and availability are not affected [1].
Mitigation
IBM recommends encrypting cluster data network traffic with IPsec as described in the IBM Cloud Private Knowledge Center. This creates encrypted channels between all nodes and services [1]. No CVE assigned to this vulnerability appears in the known exploited vulnerabilities (KEV) catalog.
