## What is CVE-2017-16690?

CVE-2017-16690 is a high-severity vulnerability in SAP Plant Connectivity, published on 12 Dec 2017. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.

### Official description

A malicious DLL preload attack possible on NwSapSetup and Installation self-extracting program for SAP Plant Connectivity 2.3 and 15.0. It is possible that SAPSetup / NwSapSetup.exe loads system DLLs like DWMAPI.dll (located in your Syswow64 / System32 folder) from the folder the executable is in and not from the system location. The desired behavior is that system dlls are only loaded from the system folders. If a dll with the same name as the system dll is located in the same folder as the executable, this dll is loaded and code is executed.

Weakness: CWE-426 (Untrusted Search Path)

Affected product: SAP Plant Connectivity. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
