Breaking change. Tool name, binary name, function/type names,
constant names, env vars, header guards, file paths, and GitHub
repo URL all rebrand IAMROOT → SKELETONKEY.
Changes:
- All "IAMROOT" → "SKELETONKEY" (constants, env vars, enum
values, docs, comments)
- All "iamroot" → "skeletonkey" (functions, types, paths, CLI)
- iamroot.c → skeletonkey.c
- modules/*/iamroot_modules.{c,h} → modules/*/skeletonkey_modules.{c,h}
- tools/iamroot-fleet-scan.sh → tools/skeletonkey-fleet-scan.sh
- Binary "iamroot" → "skeletonkey"
- GitHub URL KaraZajac/IAMROOT → KaraZajac/SKELETONKEY
- .gitignore now expects build output named "skeletonkey"
- /tmp/iamroot-* tmpfiles → /tmp/skeletonkey-*
- Env vars IAMROOT_MODPROBE_PATH etc. → SKELETONKEY_*
New ASCII skeleton-key banner (horizontal key icon + ANSI Shadow
SKELETONKEY block letters) replaces the IAMROOT banner in
skeletonkey.c and README.md.
VERSION: 0.3.1 → 0.4.0 (breaking).
Build clean on Debian 6.12.86. `skeletonkey --version` → 0.4.0.
All 24 modules still register; no functional code changes — pure
rename + banner refresh.

# NOTICE — pwnkit
|
|
|
|
## Vulnerability
|
|
|
|
**CVE-2021-4034** — pkexec argv[0]=NULL → environment-variable
|
|
injection → arbitrary code execution as root.
|
|
|
|
## Research credit
|
|
|
|
Discovered and disclosed by the **Qualys Research Team**, January 2022.
|
|
|
|
Original advisory:
|
|
<https://www.qualys.com/2022/01/25/cve-2021-4034/pwnkit.txt>
|
|
|
|
Upstream fix: polkit 0.121 (Jan 2022).
|
|
|
|
## SKELETONKEY role
|
|
|
|
The exploit module follows the canonical Qualys-style chain: writes
|
|
payload.c + gconv-modules cache, compiles via the target's gcc,
|
|
execve's pkexec with NULL argv and crafted envp. Handles both the
|
|
legacy ("0.105") and modern ("126") polkit version string formats.
|
|
Falls back gracefully on hosts without a compiler.
|
|
|
|
This is SKELETONKEY's first **userspace** LPE — not a kernel bug.
