The Dockerfile downloads and installs packages-microsoft-prod.deb with wget and then dpkg -i without any signature or checksum verification. If the download is tampered (e.g., via DNS/cert compromise or supply-chain attack), a malicious .deb can execute maintainer scripts during dpkg -i, compromising the image and persisting backdoored repositories. Verify integrity before installation (e.g., pin and check a published SHA256 checksum or verify a detached GPG signature), or install the repo using a pinned signed-by GPG key and a verified source, for example:

RUN apt-get update && apt-get install -y --no-install-recommends ca-certificates gnupg \
 && wget -O /usr/share/keyrings/microsoft.gpg https://packages.microsoft.com/keys/microsoft.asc \
 && echo "deb [arch=amd64 signed-by=/usr/share/keyrings/microsoft.gpg] https://packages.microsoft.com/debian/13/prod bookworm main" \
    > /etc/apt/sources.list.d/microsoft-prod.list

Then run apt-get update and install dotnet-sdk-10.0 from the signed repo.
