CVE-2025-42998Network attack vector

Unauthenticated restricted-page access via manipulated Host header

Published Jun 10, 2025 · Updated Jun 10, 2025

Security restriction bypass in SAP Business One Integration Framework allows remote attackers to access restricted pages. Its security checks trust a manipulated HTTP Host header, so a request that should receive 403 Forbidden is routed to protected content. No credentials or user interaction are required; the documented impact is limited to reading otherwise restricted application pages, with no integrity or availability effect.
