Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2023-38013 affects IBM Cloud Pak System versions 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. The vulnerability involves the disclosure of sensitive information in HTTP responses, classified under CWE-201 (Exposure of Sensitive Information to an Unauthorized Actor), with additional NVD-CWE-noinfo notation. It carries a CVSS v3.1 base score of 5.3 (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N), indicating medium severity primarily due to confidentiality impact.
Attackers with network access can exploit this vulnerability without authentication, privileges, or user interaction, requiring only low attack complexity. Exploitation discloses sensitive information in HTTP responses, enabling low-impact confidentiality breaches that could facilitate further attacks against the system.
IBM's security advisory at https://www.ibm.com/support/pages/node/7159533 details the issue and provides guidance on mitigations or patches for the affected versions.

Mitigating Controls (NIST 800-53 r5) AI
Directly enforces policy-based information flow rules that block transmission of sensitive data to unauthorized actors.
Enforces authorizations on logical access so that sensitive data is not released to unauthorized recipients.
Requires validation of outbound information to ensure sensitive content is not disclosed in responses or messages.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Monitoring runtime data flows and outputs can detect sensitive data being transmitted.
Protecting data-in-transit can include filtering or encrypting to avoid exposing sensitive content.
Protecting data-in-use includes removing confidential values before they are processed or sent.
Secure SDLC practices directly prevent insertion of sensitive data into application outputs and messages.
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Classification identifies sensitive data so it is not inadvertently transmitted.
Labelling makes sensitive data visible to developers and prevents accidental inclusion in outbound messages.
