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
The loginDefaultEncrypt algorithm in loginLib in Wind River VxWorks before 6.9 does not properly support a large set of distinct possible passwords, which makes it easier for remote attackers to obtain access via a (1) telnet, (2) rlogin, or (3) FTP session.

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 confidence

The loginDefaultEncrypt algorithm in VxWorks loginLib prior to version 6.9 has insufficient password space, meaning it cannot properly encrypt/distinguish a large number of unique passwords. This weakness allows remote attackers to more easily brute-force or guess credentials when accessing via telnet, rlogin, or FTP services.

MitigationUpgrade to VxWorks 6.9 or later which implements a properly designed password encryption algorithm with sufficient entropy. If upgrade is not possible, disable vulnerable remote services (telnet/rlogin/FTP) and use SSH or VPN tunnels for remote access.

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. Identify VxWorks version
    Query the system for its VxWorks version using 'vrelease' or check system documentation/banner. Compare the version number against the affected ranges: 5.5, 6, 6.4, or any version <= 6.8
    Affected if The installed version is 5.5, 6, 6.4, or any version numbered 6.8 or lower
  2. Verify loginLib is in use
    Check if the system uses loginLib for authentication by examining login configuration files or the running system configuration. Look for references to 'loginDefaultEncrypt' or 'loginLib' in system files
    Affected if loginLib with the default loginDefaultEncrypt algorithm is the active authentication mechanism
  3. Check if telnet service is enabled
    Inspect running services or network configuration to determine if the telnet daemon is active. This can be done by checking service configuration files or querying the service status
    Affected if Telnet service is enabled and accessible on the network
  4. Check if rlogin service is enabled
    Inspect running services or network configuration to determine if the rlogin daemon is active. Check service configuration or query the service status
    Affected if Rlogin service is enabled and accessible on the network
  5. Check if FTP service is enabled
    Inspect running services or network configuration to determine if the FTP daemon is active. Check service configuration or query the service status
    Affected if FTP service is enabled and accessible on the network

The environment is affected if VxWorks version is 5.5, 6, 6.4, or <= 6.8 AND any of the vulnerable remote services (telnet, rlogin, or FTP) are enabled and using loginLib authentication.

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 data
Upgrade available Upgrade to a release after 6.8
Interim mitigation

Upgrade to VxWorks 6.9 or later which implements a properly designed password encryption algorithm with sufficient entropy. If upgrade is not possible, disable vulnerable remote services (telnet/rlogin/FTP) and use SSH or VPN tunnels for remote access.
