CVE-2023-38013Network attack vector

Unauthenticated private IP disclosure via HTTP responses

Published Jan 25, 2025 · Updated Jan 27, 2025

Information disclosure in IBM Cloud Pak System allows remote attackers to read a private IP address in HTTP responses. The response-generation logic inserts an internal private IP address into content returned to unauthenticated HTTP requests. Affected versions are 2.3.3.0, 2.3.3.3, 2.3.3.3 iFix1, 2.3.3.4, 2.3.3.5, 2.3.3.6, 2.3.3.6 iFix1, 2.3.3.6 iFix2, 2.3.3.7, and 2.3.3.7 iFix1; network access is sufficient, and the disclosure supports follow-on reconnaissance without reported direct modification or service interruption.
