Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
IBM InfoSphere Information Server versions 11.7.0.0 through 11.7.1.6 are vulnerable to CVE-2025-12531, an XML external entity (XXE) injection flaw (CWE-611) that occurs when processing XML data. Published on 2025-11-03, this vulnerability carries a CVSS v3.1 base score of 7.1 (AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:H), indicating network accessibility with low attack complexity.
A remote attacker with low privileges (PR:L) can exploit this vulnerability without user interaction, achieving low-impact confidentiality loss by exposing sensitive information or high-impact availability disruption through memory resource exhaustion.

Mitigating Controls (NIST 800-53 r5) AI
Secure configuration settings can disable external entity processing in XML parsers.
Developer testing can discover XXE flaws through targeted XML parsing tests.
Input validation can reject or sanitize XML containing external entity references.
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.
Hardened XML parser configurations directly disable external entity resolution.
Secure SDLC practices include input validation and safe XML parser configuration that prevent XXE.
Vulnerability scanning can discover XXE flaws but does not prevent their introduction in code.
Patching eliminates XXE-vulnerable parser versions but is only one aspect of software maintenance.

Security testing in development catches XXE via static analysis and dynamic XML fuzzing.
Vulnerability management identifies and patches XML libraries with unsafe default entity settings.
Secure development life cycle mandates input validation and entity handling that directly prevents XXE.
Application security requirements explicitly call for disabling external entity processing in XML parsers.
Secure architecture principles include safe parser configuration that mitigates external entity risks.
Secure coding standards require disabling DTDs and external entities in XML processing.
