CVE-2021-3141
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 Unisys Stealth (core) before 6.0.025.0, the Keycloak password is stored in a recoverable format that might be accessible by a local attacker, who could gain access to the Management Server and change the Stealth configuration.
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 Unisys Stealth (core) versions before 6.0.025.0, the Keycloak password is stored in a recoverable format rather than being properly hashed or encrypted. A local attacker with access to the system could recover this password and gain unauthorized access to the Management Server, allowing them to modify Stealth configuration settings.

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 Unisys Stealth versionUse the product's built-in version reporting mechanism or check the Stealth installation directory for version metadata filesAffected if The installed version is 6.0 or higher but lower than 6.0.025.0
-
Locate Keycloak configuration filesSearch for Keycloak-related configuration files in the Stealth installation directory, typically under the configuration or conf subdirectoryAffected if Configuration files containing Keycloak password entries exist and are readable by local users
-
Inspect password storage formatExamine the Keycloak password configuration value in the relevant config file. Determine if the password appears as plaintext, base64-encoded, reversibly encrypted, or in another recoverable format rather than being stored as a salted hashAffected if The password value is stored in a recoverable encoding (plaintext, base64, reversible encryption) instead of a one-way hash
-
Verify file system permissions on credential filesCheck file system permissions on the Keycloak configuration files and any associated credential stores. Use standard OS permission checking tools to verify who can read these filesAffected if Non-administrator local users have read access to files containing the Keycloak password
-
Confirm Management Server accessibilityVerify that the Management Server component is configured and accessible from the system being checkedAffected if The Management Server is reachable and the recoverable password could be used to authenticate to it
A system is affected if Unisys Stealth version 6.0 through 6.0.025.0 is installed and Keycloak credentials are stored in a recoverable (non-hashed) format accessible to local users.

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 data6.0.025.0
Upgrade Unisys Stealth to version 6.0.025.0 or later, which implements proper password storage. If immediate patching is not possible, restrict local access to systems storing these credentials and monitor for unauthorized access to the Management Server.
