MEDIUM

Why flagged The package downloads a prebuilt binary from an official but non-whitelisted vendor host, which is a supply-chain risk if the source were swapped; it also installs a setuid binary (AvConnect), which is a potential privilege escalation vector if compromised.

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, …).

PKGBUILD:14 "https://software.sonicwall.com/CT-NX-VPNClients/CT-$(sed 's/[0-9]$/.&/' <<<"${pkgver%.*}")/ConnectTunnel_Linux64-${pkgver}.tar"
PKGBUILD:15 "https://www.sonicwall.com/legal/general-product-agreement"

MEDIUM Privileged / out-of-pacman install (sudoers, setuid, or self-update) privileged_install

The package grants elevated privileges or installs an update path outside pacman: a /etc/sudoers.d rule (often passwordless), a setuid/setgid binary, or a self-update script/service that can fetch and run future code with no checksum verification. The initial install may be verified, but the ongoing privilege + update surface is a real supply-chain / privilege-escalation risk.
