CVE-2017-7933
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 · uneditedIn ABB IP GATEWAY 3.39 and prior, some configuration files contain passwords stored in plain-text, which may allow an attacker to gain unauthorized access.
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 confidenceIn ABB IP GATEWAY 3.39 and prior, configuration files store passwords in plain-text without any encryption or hashing. An attacker who gains access to these configuration files (through file system compromise, backup exposure, or other means) can read the plaintext credentials and use them to authenticate to the system.

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 firmware versionAccess the device admin interface or check system information pages, or use command line tools like 'show version' or check /proc/version if SSH access is availableAffected if The firmware version is 3.39 or lower
-
Locate configuration filesSearch for configuration files in typical locations such as /config, /etc, /settings, or through the web interface configuration export featureAffected if Configuration files exist on the system
-
Inspect configuration files for password fieldsOpen or cat the configuration files and look for fields labeled 'password', 'passwd', or similarAffected if Password fields are present in the configuration files
-
Verify password storage formatExamine the value stored in password fields - check if it appears as plain readable text versus a hashed or encrypted string (e.g., look for $2a$, $argon2$, base64 encoding, or other non-plaintext formats)Affected if Password values appear as plain readable text with no hashing or encryption indicators
If the firmware version is 3.39 or lower AND configuration files contain passwords stored as plain readable text (not hashed or encrypted), the environment is affected by this CVE.
Generated from the published advisory. Verify against your own configuration.
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 dataUpgrade to a patched version if available, or implement proper password hashing (e.g., salted bcrypt/Argon2) for stored credentials in configuration files rather than plain-text storage, and change all exposed passwords immediately.
