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
In Delta Electronics InfraSuite Device Master versions prior to 1.0.5, an unauthenticated attacker could generate a valid token, which would lead to authentication bypass.

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

Delta Electronics InfraSuite Device Master versions prior to 1.0.5 contain an authentication bypass vulnerability where an unauthenticated attacker can generate a valid authentication token, allowing full access to the application without proper credentials. This is a critical flaw in the token generation mechanism that completely subverts the authentication layer.

MitigationUpgrade to Delta Electronics InfraSuite Device Master version 1.0.5 or later to obtain the vendor patch. If immediate patching is not possible, network segmentation and restricting access to the management interface should be implemented as compensating controls.

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 if Delta InfraSuite Device Master is installed
    Locate the InfraSuite Device Master installation on the system. Check for the application in standard installation directories or review installed software listings.
    Affected if Delta Electronics InfraSuite Device Master software is present on the system
  2. Determine the installed version
    Access the application or its configuration files to retrieve the current version number. This is typically available in the application UI under About/Help, or in version metadata files within the installation directory.
    Affected if The version cannot be determined or is not visible
  3. Compare version to affected range
    Review the identified version against the affected range: versions prior to 1.0.5 are vulnerable.
    Affected if The installed version is 1.0.4 or lower, or any version number less than 1.0.5
  4. Verify network accessibility of management interface
    Determine if the Device Master web management interface is exposed to the network. Check firewall rules, NAT configurations, or access control lists that govern access to the application ports.
    Affected if The management interface is externally accessible or accessible from untrusted networks

A system is affected if Delta Electronics InfraSuite Device Master is installed with any version prior to 1.0.5 and the management interface is network-accessible.

Upgrade available Upgrade to 1.0.5 or later
Fixed in 1.0.5
Interim mitigation

Upgrade to Delta Electronics InfraSuite Device Master version 1.0.5 or later to obtain the vendor patch. If immediate patching is not possible, network segmentation and restricting access to the management interface should be implemented as compensating controls.

Recommended fix High confidence

1.0.5

  1. 1. Identify all deployed instances of Delta Electronics InfraSuite Device Master
  2. 2. Verify current version of each instance is below 1.0.5
  3. 3. Schedule a maintenance window for the upgrade process
  4. 4. Obtain the Infrasuite Device Master version 1.0.5 from official Delta Electronics distribution channels
  5. 5. Follow Delta Electronics official upgrade procedure to update from current version to 1.0.5
  6. 6. After upgrade, verify the version has been successfully updated to 1.0.5
  7. 7. Test that the authentication mechanism now properly validates tokens and prevents unauthorized access
  8. 8. Monitor for any unexpected behavior following the upgrade
