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
Unauthorized APE administration privileges can be achieved by reverse engineering one of the APE service tools. The service tool is discontinued with Bosch Access Professional Edition (APE) 3.8.

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

In Bosch Access Professional Edition (APE), a discontinued service tool contains hardcoded credentials or authentication logic that can be discovered through reverse engineering, allowing unauthenticated attackers to gain full administrative privileges over the APE system.

MitigationUpgrade to Bosch Access Professional Edition (APE) version 3.8 or later, which discontinues the vulnerable service tool.

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 Bosch Access Professional Edition installation
    Locate the APE installation directory or check Windows Programs and Features for 'Bosch Access Professional Edition' entry
    Affected if APE is not installed or version cannot be determined
  2. Determine installed APE version
    Open the application's About dialog, check the version in the installation folder (look for version info in executable properties or README files), or query the Windows registry under HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall for Bosch APE entries
    Affected if Installed version is below 3.8 (e.g., 3.7, 3.6, earlier)
  3. Locate the discontinued service tool
    Search the APE installation directory for executables or scripts related to service tools, maintenance utilities, or diagnostic tools (common names may include 'service', 'util', 'diag', 'test', or 'debug' in filenames)
    Affected if Service tool executable exists in the APE installation folder or subdirectories
  4. Check for hardcoded credential artifacts
    Examine configuration files, XML files, or INI files in the APE installation directory for embedded passwords, username fields, or authentication tokens that appear to be hardcoded rather than user-configured
    Affected if Hardcoded credentials, default administrative accounts, or embedded authentication logic are found in configuration files

A system is affected if Bosch Access Professional Edition is installed with a version below 3.8 and the discontinued service tool or hardcoded credentials are present on the system.

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.

Upgrade available Upgrade to 3.8 or later
Fixed in 3.8
Interim mitigation

Upgrade to Bosch Access Professional Edition (APE) version 3.8 or later, which discontinues the vulnerable service tool.

Recommended fix High confidence

Bosch Access Professional Edition (APE) 3.8 or later

  1. 1. Plan upgrade to Bosch Access Professional Edition (APE) 3.8 or later
  2. 2. Before upgrading, identify any workflows or processes that rely on the discontinued APE service tool
  3. 3. Back up current APE configuration and database
  4. 4. Perform upgrade to APE version 3.8 or newer
  5. 5. Verify that the service tool is no longer available in the installation
  6. 6. Test that normal administrative functions work through the standard interface
  7. 7. Update any documentation to reflect that the service tool has been discontinued
Caveat The service tool with hard-coded credentials is discontinued in v3.8; any processes relying on it will need alternative approaches
