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 · unedited
A weak encryption algorithm is used for passwords in SCO TermVision, allowing them to be easily decrypted by a local user.

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 · low confidence

SCO TermVision uses a weak encryption algorithm to protect stored passwords, enabling a local user to easily decrypt them and potentially gain elevated access.

MitigationIf SCO TermVision is still in use, evaluate migrating to a supported terminal emulation solution with modern password storage mechanisms; otherwise, restrict local access to trusted personnel only.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Verify SCO TermVision installation
    Check if SCO TermVision software package is installed on the system using package management commands or inventory listings
    Affected if SCO TermVision is present on the system
  2. Locate TermVision password storage files
    Search for configuration or password files associated with TermVision, typically found in application data directories or user home directories
    Affected if Password files created by TermVision exist on the system
  3. Inspect password encryption method
    Examine the stored password files to identify the encryption algorithm used; weak or reversible encryption indicates vulnerability
    Affected if Stored passwords use weak or reversible encryption rather than cryptographic hashing
  4. Check TermVision service status
    Determine if TermVision daemon or service is actively running on the system
    Affected if TermVision service is enabled and running

A system is affected if SCO TermVision is installed and stores user credentials using weak encryption that can be easily decrypted by a local user.
