CVE-2020-7492
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 · uneditedA CWE-521: Weak Password Requirements vulnerability exists in the GP-Pro EX V1.00 to V4.09.100 which could cause the discovery of the password when the user is entering the password because it is not masqueraded.
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 · high confidenceIn GP-Pro EX versions 1.00 through 4.09.100, password input fields do not mask characters as users type, causing passwords to display in plaintext on screen. This allows observers to capture passwords via shoulder surfing, screen recording, or unintended screen visibility.

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 the installed GP-Pro EX firmware versionAccess the system information or about section within the GP-Pro EX software, or check the firmware version displayed on the HMI device or project settings. Common locations: Help > About, or system setup screens showing firmware revision.Affected if The firmware version is greater than or equal to 1.00 and less than or equal to 4.09.120 (or between 1.00 and 4.09.100 if the 4.09.120 value was not confirmed).
-
Locate password input fields in the applicationNavigate to any screen within GP-Pro EX that contains password-protected elements, such as system login screens, user account settings, or security configuration panels where passwords are entered or configured.Affected if Password input fields are present in the application.
-
Observe password masking behavior during inputClick into a password input field and type characters. Visually inspect whether the typed characters appear as plaintext (fully visible letters/numbers) or as masked characters (asterisks, dots, or circles).Affected if Characters typed into password fields appear as plaintext rather than being replaced by masking characters such as asterisks or dots.
A user is affected if their GP-Pro EX firmware version falls within 1.00 to 4.09.120 AND password input fields display unmasked plaintext characters when typing.

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 dataUntil a patched version is released, users should enter passwords only in private, physically secure locations and consider using virtual keyboards in isolated environments. The vendor should implement standard password masking (e.g., asterisks or dots) in input fields.
