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
ABB DataManagerPro 1.x before 1.7.1 allows local users to gain privileges by replacing a DLL file in the package directory.

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

ABB DataManagerPro versions prior to 1.7.1 are vulnerable to DLL hijacking. The application loads DLL files from a directory where local, unprivileged users have write access, allowing them to replace legitimate DLLs with malicious ones and execute code with elevated privileges when the application runs.

MitigationUpgrade to ABB DataManagerPro version 1.7.1 or later, which addresses the DLL loading vulnerability. As a temporary measure, restrict write access to the application directory to prevent unauthorized DLL replacement.

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 ABB DataManagerPro is installed
    Check for the presence of ABB DataManagerPro in the system. Common installation paths include C:\Program Files\ABB\DataManagerPro or C:\Program Files (x86)\ABB\DataManagerPro. Look for the executable file DataManagerPro.exe or check Windows Registry under HKEY_LOCAL_MACHINE\SOFTWARE\ABB\DataManagerPro or HKEY_CURRENT_USER\SOFTWARE\ABB\DataManagerPro.
    Affected if The product is found on the system and the version is prior to 1.7.1.
  2. Identify if Trane Tracer Sc is installed
    Check for the presence of Trane Tracer Sc. Look for the executable TracerSC.exe or similar. Check common installation paths or search the filesystem. Verify through Windows Registry if available.
    Affected if The product is found on the system and the version is 4.2.1134 or lower.
  3. Determine installed version of ABB DataManagerPro
    Right-click on DataManagerPro.exe, select Properties, and view the Version tab. Alternatively, query the Windows Registry for the Version value under the ABB DataManagerPro registry key, or use the command: reg query "HKLM\SOFTWARE\ABB\DataManagerPro" /v Version
    Affected if The reported version is lower than 1.7.1.
  4. Determine installed version of Trane Tracer Sc
    Right-click on the Tracer Sc executable, select Properties, and view the Version tab to find the file version. Compare this against the affected version 4.2.1134.
    Affected if The file version is 4.2.1134 or lower.
  5. Check write permissions on the application directory
    Right-click on the directory where ABB DataManagerPro or Trane Tracer Sc is installed, select Properties, go to the Security tab, and examine the permissions for Users or Everyone. Alternatively, use icacls from command prompt: icacls "C:\Path\To\Application" (replace with actual path). Look for entries showing (F) for Full control or (W) for Write permission for non-admin groups like Users or Everyone.
    Affected if Non-privileged users (such as standard user accounts) have Write or Full Control permissions to the application directory.

A user is affected if ABB DataManagerPro version prior to 1.7.1 or Trane Tracer Sc version 4.2.1134 or lower is installed, AND the application directory is writable by non-privileged local users.
