CVE-2025-42979

RFC password disclosure via reversible registry obfuscation

Published Jul 8, 2025 · Updated Jul 8, 2025

Insecure credential storage in GuiXT for SAP GUI for Windows 8.00 allows local users to recover an RFC user's password. GuiXT obfuscates RFC credentials stored in the user's Windows registry hive instead of protecting them with a secure symmetric cipher. Read access to that user's registry hive is required, and recovery exposes the original RFC password without affecting application integrity or availability.
