CVE-2025-0159Network attack vector

Unauthenticated RPCAdapter access via crafted HTTP request

Published Feb 28, 2025 · Updated Feb 26, 2026

Authentication bypass in IBM Storage Virtualize 8.5, 8.6, and 8.7 allows remote attackers to access RPCAdapter endpoints via crafted HTTP requests. The GUI RPCAdapter accepts a specially crafted HTTP request without enforcing endpoint authentication; IBM has not disclosed the route or parsing condition. No credentials or user interaction are required, and the documented impact is unauthorized disclosure and modification without service interruption.
