CVE-2023-28509
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 · uneditedRocket Software UniData versions prior to 8.2.4 build 3003 and UniVerse versions prior to 11.3.5 build 1001 or 12.2.1 build 2002 use weak encryption for packet-level security and passwords transferred on the wire.
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 confidenceRocket Software UniData and UniVerse databases use weak encryption for packet-level security, allowing sensitive data including passwords transmitted over the network to be intercepted or compromised. The vulnerability affects versions prior to the specified builds, enabling man-in-the-middle attacks against the unencrypted or weakly encrypted communications.

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 product and versionLocate the UniData or UniVerse installation directory and check version information in the binaries, release notes, or use product-specific commands such as 'uv -version' for UniVerse or check the 'ud version' output for UniDataAffected if The installed version is UniData <= 8.2.4 or UniVerse <= 11.3.5 or UniVerse >= 12.0.0 through 12.2.1
-
Confirm network services are enabledCheck if the database network listener or RPC services are running and configured to accept remote connections. Examine process lists and network configuration for udatasrv (UniData) or uv (UniVerse) listener processesAffected if Network services are enabled and accepting connections from remote clients or other systems
-
Verify network encryption configurationExamine the database network configuration files and runtime settings for encryption parameters. Look for settings related to packet-level security, SSL/TLS configuration, or encryption flags in the network configurationAffected if Encryption is disabled, set to weak encryption, or using default legacy encryption settings for network communications
A user is affected if they are running an affected version of UniData or UniVerse with network services enabled and weak or no encryption configured for network communications.

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.
dbcve · scopedUpgrade UniData to version 8.2.4 build 3003 or later, and UniVerse to version 11.3.5 build 1001 or 12.2.1 build 2002 or later to obtain the patched encryption mechanisms.
UniData 8.2.4 build 3003 | UniVerse 11.3.5 build 1001 or 12.2.1 build 2002
- Identify the current UniData or UniVerse version and build number running in the environment
- For UniData: Plan upgrade to version 8.2.4 build 3003 or later
- For UniVerse 11.x: Plan upgrade to version 11.3.5 build 1001 or later
- For UniVerse 12.x: Plan upgrade to version 12.2.1 build 2002 or later
- Review Rocket Software's upgrade documentation and release notes for the target version
- Perform the upgrade following vendor-provided procedures
- After upgrade, verify the version and build number reflect the fixed release
- Test that application functionality remains operational post-upgrade
