CVE-2020-16280
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 · uneditedMultiple Rangee GmbH RangeeOS 8.0.4 modules store credentials in plaintext including credentials of users for several external facing administrative services, domain joined users, and local administrators. To exploit the vulnerability a local attacker must have access to the underlying operating system.
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 confidenceRangeeOS 8.0.4 multiple modules store user credentials in plaintext rather than using secure hashing or encryption. Exposed credentials include those for external-facing administrative services, domain-joined user accounts, and local administrator accounts. A local attacker with OS access can read these plaintext credentials to escalate privileges or pivot to other systems.

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.
-
Confirm the RangeeOS versionCheck the installed Rangeeos version by reviewing system information, about pages, or running version commands specific to the Rangeeos appliance. Look for version 8.0.4 specifically.Affected if The installed version is exactly 8.0.4
-
Identify active modules or servicesEnumerate all modules, services, or components running on the Rangeeos system. Review the configuration or management interface to see which modules are enabled.Affected if Any module that handles user authentication or stores credentials is enabled on the system
-
Locate credential storage locationsSearch for configuration files, databases, or directories where user credentials are stored. Look in typical credential storage areas such as config directories, user databases, or service account storage.Affected if Credentials are found stored in configuration files, databases, or storage mechanisms used by the modules
-
Examine credential formatOpen the files or storage locations found in the previous step and inspect whether passwords appear as plaintext strings, hashed values, or encrypted content. Compare the format against expected salted hash or encrypted representations.Affected if Any credentials are readable as plaintext strings rather than being stored as salted hashes or encrypted values
A system is affected if it runs Rangeeos version 8.0.4 with any modules enabled that store user credentials, and those credentials are stored in plaintext rather than being hashed or encrypted.

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 dataImplement secure credential storage using salted hashing for passwords and encryption for service credentials. Immediately rotate all exposed credentials and audit all modules for plaintext credential storage.
