MEDIUM

Why flagged The PKGBUILD downloads prebuilt binary .deb packages from dl.hostbuf.com (the vendor's own distribution host for FinalShell, a proprietary Chinese SSH/server management tool) and installs them directly without building from source. The sha256sums are pinned, which mitigates tampering at rest, but the binaries are closed-source executables from a single vendor-controlled CDN with no independent verification. FinalShell is a proprietary application with a history of controversy around its network behavior (phone-home, telemetry). The risk is a real supply-chain concern: if dl.hostbuf.com is compromised or the vendor pushes malicious updates, users receive arbitrary code execution as the installed binary runs with user privileges. This is a textbook medium: not clearly malicious, but executed closed-source binaries from a non-auditable unofficial/vendor host with no source build path.

Triggered rules

MEDIUM source=() URL on a non-standard host source_untrusted_domain

One or more source=() URLs point to a host outside the trusted allowlist (github.com, gitlab.com, codeberg.org, pypi.org, …).
