CVE-2020-6771
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 · uneditedLoading a DLL through an Uncontrolled Search Path Element in Bosch IP Helper up to and including version 1.00.0008 potentially allows an attacker to execute arbitrary code on a victim's system. A prerequisite is that the victim is tricked into placing a malicious DLL in the same application directory as the portable IP Helper application.
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 confidenceBosch IP Helper up to version 1.00.0008 is vulnerable to DLL hijacking due to an uncontrolled search path element. The portable application loads DLLs without specifying absolute paths, causing Windows to search the application directory first. An attacker who tricks a user into placing a malicious DLL with a matching name in the application's directory can achieve arbitrary code execution when the application is launched.

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 checksWork through these to decide whether this CVE applies to you.
-
Locate Bosch IP Helper executableSearch for files named 'IPHelper.exe', 'BoschIPHelper.exe', or similar in the system using Windows Explorer search or command: dir /s /b C:\*.exe 2>nul | findstr /i "ip.*helper"Affected if The executable is found on the system
-
Verify installed versionRight-click the executable, select Properties, then view the Details tab for Product Version. Alternatively, use PowerShell: (Get-Item 'C:\path\to\executable').VersionInfo.ProductVersionAffected if Version is 1.00.0008 or lower
-
Determine if portable installationCheck if the application runs from a user-writable location (USB drive, shared network folder, or a folder in user's Documents/Desktop). Inspect the installation method: portable apps typically lack entries in Windows Add/Remove Programs and do not install to Program FilesAffected if Application runs from a directory where standard users can create or modify files (portable deployment scenario)
-
Inspect application directory for unexpected DLLsList all DLL files in the same folder as the executable: dir "C:\path\to\application\*.dll". Check for DLLs with names matching commonly hijacked libraries (e.g., version.dll, winhttp.dll, crypt32.dll) that are not part of the official installationAffected if Unexpected or suspicious DLL files are present in the application directory
User is affected if Bosch IP Helper version 1.00.0008 or earlier is installed as a portable application running from a directory where unprivileged users can place files, enabling DLL hijacking.

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.
From vendor dataReplace all DLL loading calls with secure alternatives that specify absolute paths or use SetDllDirectory to remove the current directory from the DLL search order. Implement DLL signature verification before loading and digitally sign all application DLLs to prevent tampering.
