CVE-2023-33857Network attack vector

Unauthenticated system information disclosure via crafted query

Published Jul 16, 2023 · Updated Oct 31, 2024

Information disclosure in IBM InfoSphere Information Server 11.7 allows remote attackers to obtain system information via a crafted query. IBM has not disclosed the affected query handler or the operation that returns the system details, so the code-level mechanism is not public. No authentication or user interaction is required, and the disclosed impact is limited to reading system information that can guide further attacks.
