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
Authentication Bypass Using an Alternate Path or Channel vulnerability in Universal Software Inc. FlexCity/Kiosk allows Privilege Escalation. This issue affects FlexCity/Kiosk: from 1.0 before 1.0.36.

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 · moderate confidence

The FlexCity/Kiosk application from Universal Software Inc. contains an authentication bypass vulnerability (CWE-287) that allows attackers to bypass normal authentication mechanisms through an alternate path or channel, enabling privilege escalation from lower-privileged to higher-privileged accounts.

MitigationUpdate FlexCity/Kiosk to version 1.0.36 or later to remediate this vulnerability. If immediate patching is not possible, implement additional access controls and monitor for unauthorized access attempts.

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 FlexCity/Kiosk installation and version
    Locate the FlexCity/Kiosk application on the system and retrieve its version number. This is typically found in the application properties, an about dialog, or a version file within the installation directory.
    Affected if The installed version is Uni Yaz Flexcity and is less than 1.0.36 (versions 1.0.x through 1.0.35 are affected).
  2. Verify the application is running with authentication enabled
    Check the application configuration or runtime status to confirm that authentication mechanisms are currently active or configured for use.
    Affected if Authentication is enabled but can be bypassed through the alternate path or channel vulnerability.
  3. Confirm network accessibility of the authentication interface
    Determine if the FlexCity/Kiosk authentication interface is exposed over the network or accessible remotely rather than only locally.
    Affected if The authentication interface is accessible remotely, allowing external attackers to exploit the bypass.
  4. Check for presence of lower-privileged user accounts
    Review the user accounts configured in FlexCity/Kiosk to confirm the existence of lower-privileged accounts that could be escalated to higher-privileged access.
    Affected if Lower-privileged accounts exist that could be elevated through the authentication bypass.

The environment is affected if Uni Yaz Flexcity version is 1.0.x where x is less than 36, authentication is enabled, and the application is accessible for remote exploitation.

Upgrade available Upgrade to 1.0.36 or later
Fixed in 1.0.36
Interim mitigation

Update FlexCity/Kiosk to version 1.0.36 or later to remediate this vulnerability. If immediate patching is not possible, implement additional access controls and monitor for unauthorized access attempts.

Recommended fix Moderate confidence

FlexCity/Kiosk version 1.0.36

  1. 1. Identify all deployed instances of FlexCity/Kiosk in your environment
  2. 2. Determine the current installed version of each FlexCity/Kiosk instance
  3. 3. For instances running version >= 1.0 and < 1.0.36, plan the upgrade to version 1.0.36
  4. 4. Before upgrading, perform a complete backup of the current system configuration and data
  5. 5. Review the release notes for version 1.0.36 to understand any specific upgrade requirements
  6. 6. Execute the upgrade to version 1.0.36 following the vendor's documented upgrade procedure
  7. 7. After upgrade, verify that the authentication mechanism is functioning correctly
  8. 8. Test that privilege escalation is no longer possible through alternate paths or channels
