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 attacker could use URL decoding to retrieve system files, credentials, and bypass authentication resulting in privilege escalation.

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

Delta Electronics InfraSuite Device Master versions prior to 1.0.5 contain a path traversal vulnerability exploitable via URL encoding manipulation. Attackers can decode URL-encoded paths to access sensitive system files, retrieve stored credentials, bypass authentication mechanisms, and escalate privileges to administrative levels.

MitigationUpgrade to InfraSuite Device Master version 1.0.5 or later. Implement strict input validation on all URL parameters, disable directory listing, and restrict file system access permissions as additional hardening until the patch can be applied.

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 InfraSuite Device Master installation and version
    Locate the InfraSuite Device Master application on the system and determine its installed version number. This may be found in the application itself, in installed programs list, or in version information files within the application directory.
    Affected if The installed version is lower than 1.0.5 (for example, 1.0.4, 1.0.3, or earlier)
  2. Confirm web interface accessibility
    Verify that the InfraSuite Device Master web interface is accessible on the network. This vulnerability is exploitable through HTTP requests, so an exposed web service is required for the flaw to be triggered.
    Affected if The web interface is exposed and accepts HTTP requests from potential attackers
  3. Check for URL-encoded path traversal vulnerability
    Test whether the web application properly handles URL-encoded path sequences such as %2e%2e%2f (encoded ../). Submit a request with encoded path traversal sequences to see if the application returns files outside the intended directory.
    Affected if The application returns file contents or directory listings for paths outside the web root when using URL-encoded traversal sequences
  4. Look for unauthorized file access indicators
    Review web server access logs for requests containing encoded path sequences (%2e, %2f, %5c) or unusual path patterns. Check if sensitive files such as configuration files, credential stores, or system files have been accessed unexpectedly.
    Affected if Logs show successful requests with URL-encoded path traversal sequences or evidence of unauthorized file access

A user is affected if InfraSuite Device Master version is below 1.0.5 AND the web interface is accessible, allowing attackers to exploit URL-encoded path traversal to access sensitive files or bypass authentication.

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

Upgrade to InfraSuite Device Master version 1.0.5 or later. Implement strict input validation on all URL parameters, disable directory listing, and restrict file system access permissions as additional hardening until the patch can be applied.

Recommended fix High confidence

1.0.5

  1. 1. Identify all instances of Infrasuite Device Master currently deployed
  2. 2. Verify the current version of each instance (versions prior to 1.0.5 are vulnerable)
  3. 3. Obtain the patched version 1.0.5 from the vendor's official distribution channel
  4. 4. Follow vendor-provided upgrade documentation to apply version 1.0.5
  5. 5. After upgrade, verify the version has been correctly applied
  6. 6. Test that the path traversal vulnerability is no longer exploitable
