CVE-2023-47160Network attack vector

Information disclosure and memory exhaustion via external entities

Published Feb 19, 2025 · Updated Aug 17, 2025

XXE in IBM Controller 11.0.0 through 11.0.1 FP3 and 11.1.0 allows remote attackers to disclose data or exhaust memory. IBM identifies XML processing as the locus but has not disclosed the parser, endpoint, or exact operation that permits external entity resolution. No authentication or user interaction is required, and exploitation can read resources available to the server process or degrade service by consuming memory.
