CVE-2021-40503
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 · uneditedAn information disclosure vulnerability exists in SAP GUI for Windows - versions < 7.60 PL13, 7.70 PL4, which allows an attacker with sufficient privileges on the local client-side PC to obtain an equivalent of the user’s password. With this highly sensitive data leaked, the attacker would be able to logon to the backend system the SAP GUI for Windows was connected to and launch further attacks depending on the authorizations of the user.

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 SAP Logon, click 'About SAP Logon' or check Help > About. Alternatively, locate sapgui.exe in the SAP GUI installation directory (commonly C:\Program Files\SAP\SAPGUI) and view file properties to see the version. You can also check the Windows Registry under HKLM\SOFTWARE\SAP\SAPGUI\CurrentVersion for the Version value.Affected if The version displayed is any release prior to 7.60, or is exactly 7.60 or 7.70 (without the respective PL13 or PL4 patch level).
-
Confirm patch level for version 7.60If the version shows 7.60, verify the Patch Level (PL) by viewing the same version information source used in the previous step. The full version string typically appears as something like '7.60 PL13' or '7.60.0.13'.Affected if The patch level is below PL13 (for example, PL0 through PL12) or the patch level information is missing entirely.
-
Confirm patch level for version 7.70If the version shows 7.70, verify the Patch Level (PL) by viewing the version information. Check if it shows '7.70 PL4' or higher.Affected if The patch level is below PL4 (for example, PL0 through PL3) or the patch level information is missing entirely.
-
Check for stored SAP credentialsReview whether the system has saved user credentials for SAP connections. In SAP Logon, go to Options > Security Settings > Secure Storage or check if 'Save password' has been enabled for any SAP system entries in the connection list.Affected if Saved credentials exist in SAP Logon's secure storage and the installed SAP GUI version falls within the affected version range.
Your environment is affected if the installed SAP GUI for Windows version is any release prior to 7.60, or is exactly 7.60 with patch level below PL13, or is exactly 7.70 with patch level below PL4, and you have stored credentials in the application.
