Description

Adversaries may exploit software vulnerabilities that can cause an application or system to crash and deny availability to users.

Security Summary

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.
