CVE-2021-21448
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedSAP GUI for Windows, version - 7.60, allows an attacker to spoof logon credentials for Application Server ABAP backend systems in the client PCs memory. Under certain conditions the attacker can access information which would otherwise be restricted. The exploit can only be executed locally on the client PC and not via Network and the attacker needs at least user authorization of the Operating System user of the victim.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceSAP GUI for Windows 7.60 contains a vulnerability allowing local attackers to spoof ABAP backend system credentials stored in client PC memory. With local access and OS user-level permissions, an attacker can manipulate credential data to access restricted information.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify installed SAP GUI versionOpen Windows Control Panel, navigate to Programs and Features, or use 'sapgui.exe -version' from the SAP GUI installation directory to confirm the exact version numberAffected if Version displayed is 7.60 specifically (not higher or lower)
-
Verify ABAP backend connections existOpen SAP Logon (SAP GUI), check the list of saved connections in the SAP Logon Pad. Look for configured SAP System entries with stored credentialsAffected if User has configured and saved ABAP system connections with remembered passwords in SAP GUI 7.60
-
Confirm local access exposure riskReview system access controls: check if multi-user login is enabled, verify who has physical access to the workstation, and identify local user accounts with permissions to access the machineAffected if Multiple users have local access or the workstation can be accessed by unauthorized personnel
-
Assess local privilege levelCheck if standard users (non-administrators) can access the system and examine running processes for SAP GUI components using Task Manager or system diagnostic toolsAffected if Users with basic OS-level permissions can log into the local machine where SAP GUI 7.60 is running with saved credentials
User is affected if SAP GUI version 7.60 is installed with configured ABAP connections and the workstation is accessible to users with local OS-level permissions (beyond the legitimate owner).

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataRestrict physical and local console access to client workstations; ensure users lack local administrative privileges; apply SAP security patches when available; consider memory protection tools for credential storage.
