Ansible detector scanner playbook to verify target Linux hosts using the official Red Hat Log4j detector script RHSB-2021-009 Remote Code Execution - log4j (CVE-2021-44228)
介绍
# Log4j-CVE-2021-44228 detector scanner playbook
[](https://github.com/lucab85/log4j-cve-2021-44228/actions/workflows/ci.yml)
Ansible playbook to verify target Linux hosts using the official Red Hat Log4j detector script for Log4Shell (CVE-2021-44228).
[Red Hat version 1.3 detector 2022-01-10](https://access.redhat.com/security/vulnerabilities/RHSB-2021-009).
The result is saved in a txt file under `detector_dir` (default: `/opt/cve-2021-44228/`).
## Ansible Galaxy role
Code also available as Ansible Galaxy role [lucab85.ansible_role_log4shell](https://galaxy.ansible.com/lucab85/ansible_role_log4shell)
```bash
ansible-galaxy install lucab85.ansible_role_log4shell
```
## How to run the Ansible Playbook
Default variables scan all the `/var/` path for affected files.
You could customize the `vars.yml` file for more options.
```bash
ansible-playbook log4j-cve-2021-44228.yml
```
## Dependencies
None.
## Requirements
ansible 2.9+
## Variables vars.yml
default values:
```yaml
rh_bullettin: >-
https://access.redhat.com/security/vulnerabilities/RHSB-2021-009
intro: |
Ansible Playbook tested with detector version 1.3 released 2022-01-10.
If a 404 error occur please adjust the URL with the latest version available
for detector URL.
Please refer to the Red Hat Security Bullettin for up-to-date information and
adjust the playbook variables accordingly.

- `rh_bullettin`: link of the RHSB (default: [https://access.redhat.com/security/vulnerabilities/RHSB-2021-009](https://access.redhat.com/security/vulnerabilities/RHSB-2021-009))
- `intro`: introduction text
- `vulnerable`: vulnerable text (visible only on debug level 2 execution `-vv`)
- `not_vulnerable`: NOT vulnerable text (visible only on debug level 2 execution `-vv`)
- `report_txt`: report path to print (default: `/report/vuln_log4j2_path_*.txt`)
- `sh_detector`: the filename of the detector bash script file
- `sh_signature`: the filename of the detector GPG signature file
- `detector_baseurl`: the base URL to download the previous files
- `force_download`: force to download every run the code (default: `false`)
- `detector_path`: the path to inspect (default `/var/`)
- `detector_dir`: the download path of the detector (default `/opt/cve-2021-44228/`)
- `detector_run_dir`: the subdirectory to create before the run (default `tmp`)
- `detector_options`: the command lines options for detector script (default `-n -d --no-progress --scan {{ detector_path }}`)
- `gpg_keyid`: the GPG public key to download for the verification (default Red Hat Product Security `7514F77D8366B0D9`)
- `gpg_server`: the GPG key server (default: `pgp.mit.edu`)
- `gpg_public_key`: command for gpg verification (default: `gpg --keyserver {{ gpg_server }} --recv {{ gpg_keyid }}`)
- `clean_run_before`: remove the run directory and recreate before the execution - detector requires an empty directory (default `true`)
- `delete_after`: remove the _detector_dir_ after the execution (default `false`)
- `verify_gpg`: perform the GPG signature download and verification (default: `true`)
