## What is CVE-2019-17201?

CVE-2019-17201 is a critical missing authorization vulnerability in n/a, published on 23 Jan 2020. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

FastTrack Admin By Request 6.1.0.0 supports group policies that are supposed to allow only a select range of users to elevate to Administrator privilege at will. When a user requests elevation using the AdminByRequest.exe interface, the interface communicates with the underlying service (Audckq32.exe) using a .NET named pipe. If the underlying service responds that a user is permitted access to the elevation feature, the client then reinitiates communication with the underlying service and requests elevation. This elevation request has no local checks in the service, and depends on client-side validation in the AdminByRequest.exe interface, i.e., it is a vulnerable exposed functionality in the service. By communicating directly with the underlying service, any user can request elevation and obtain Administrator privilege regardless of group policies or permissions.

Check this codebase for CVE-2019-17201 and fix it if it is affected.

What it is: CVE-2019-17201 is a critical missing authorization vulnerability in n/a, published on 23 Jan 2020. It can only be exploited from the same machine or local network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2019-17201 in the wild and no public exploit code.

Affected product: n/a. 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.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
