CVE-2021-21448

Local information disclosure via credential spoofing

Published Jan 12, 2021 · Updated Aug 3, 2024

Information disclosure in SAP GUI for Windows 7.60 allows local users to access restricted data by spoofing ABAP backend logon credentials. SAP has not disclosed the code locus or how client-memory handling accepts the spoofed credential state and exposes protected information. Exploitation requires access under the victim's operating-system account on the client PC and is not reachable over a network; the bounded impact is disclosure of otherwise restricted information.
