## What is afrog afrog is a high-performance vulnerability scanner that is fast and stable. It supports user-defined PoC and comes with several built-in types, such as CVE, CNVD, default passwords, information disclosure, fingerprint identification, unauthorized access, arbitrary file reading, and command execution. With afrog, network security professionals can quickly validate and remediate vulnerabilities, which helps to enhance their security defense capabilities. ## Features - [x] Open source - [x] Fast, stable, with low false positives - [x] Detailed HTML vulnerability reports - [x] Customizable and stably updatable PoCs - [x] Port pre-scan (PortScan) for open port discovery - [x] Active community exchange group ## Installation ### Prerequisites - [Go](https://go.dev/) version 1.24 or higher. you can install it with: **Binary** ```sh $ https://github.com/zan8in/afrog/releases/latest ``` **Github** ```sh $ git clone https://github.com/zan8in/afrog.git $ cd afrog $ go build cmd/afrog/main.go $ ./afrog -h ``` **Go** ```sh $ go install -v github.com/zan8in/afrog/v3/cmd/afrog@latest # Confirm Go’s bin path is in your environment $ ls ~/go/bin/afrog # Make it runnable from anywhere (add ~/go/bin to PATH) # Permanently (Bash — add to ~/.bashrc): $ echo 'export PATH=$PATH:~/go/bin' >> ~/.bashrc $ source ~/.bashrc # If you use Zsh: $ echo 'export PATH=$PATH:~/go/bin' >> ~/.zshrc $ source ~/.zshrc ``` ## Running afrog By default, afrog scans all built-in PoCs, and if it finds any vulnerabilities, it automatically creates an HTML report with the date of the scan as the filename. ```sh afrog -t https://example.com ``` **Warning occurs when running afrog** If you see an error message saying: ``` [ERR] ceye reverse service not set: /home/afrog/.config/afrog/afrog-config.yaml ``` it means you need to modify the [configuration file](#configuration-file). To execute a custom PoC directory, you can use the following command: ```sh afrog -t https://example.com -P mypocs/ ``` Use the command `-s keyword` to perform a fuzzy search on all PoCs and scan the search results. Multiple keywords can be used, separated by commas. For example: `-s weblogic,jboss`. ```sh afrog -t https://example.com -s weblogic,jboss ``` Use the command `-S keyword` to scan vulnerabilities based on their severity level. Severity levels include: `info`, `low`, `medium`, `high`, and `critical`. For example, to only scan high and critical vulnerabilities, use the command `-S high,critical`. ```sh afrog -t https://example.com -S high,critical ``` You can scan multiple URLs at the same time as well. ```sh afrog -T urls.txt ``` ### Port Pre-scan (PortScan) PortScan runs before PoC scanning to discover open ports. Discovered ports will be appended to the scan target set (as `host:port`), and subsequent PoCs will run against the updated targets. ```sh # Single-target full port scan afrog -t 1.2.3.4 -ps -p all # Network segment scan (host discovery + common port scan) afrog -t 1.2.3.4/24 -ps # Skip host discovery (assume target is reachable) afrog -T targets.txt -ps -Pn # Scan only specified ports afrog -t example.com -ps -p 80,443,8080 ``` Common flags: - `-ps` / `--portscan`: enable port pre-scan - `-p` / `--ports`: ports definition (e.g. `top`, `full`, `all`, `80,443`, `1-1024`) - `-Pn` / `--ps-skip-discovery`: skip host discovery - `-prate` / `--ps-rate`: portscan rate limit - `-ptimeout` / `--ps-timeout-ms`: portscan timeout (ms) - `-ptries` / `--ps-retries`: portscan retries - `--ps-s4-chunk`: chunk size when ports=`full` ## -web Command The `-web` command allows for persistently storing vulnerabilities scanned by afrog into an SQLite3 database. Accessing http://x.x.x.x:16868 via a browser provides access to the vulnerability report webpage, where users can conduct simple keyword searches and filter results by vulnerability severity. ```shell afrog -web ```

## Configuration file The first time you start afrog, it will automatically create a configuration file called `afrog-config.yaml`, which will be saved in the current user directory under `$HOME/.config/afrog/afrog-config.yaml`. Here is an example config file: ```yaml curated: enabled: "auto" # auto|on|off endpoint: "" # curated service endpoint, leave empty to disable online update auto_update: true # automatically check for curated updates timeout_sec: 10 # mount/update timeout in seconds channel: "stable" # curated channel, e.g. stable/beta license_key: "" # your curated license key (if you have one) reverse: ceye: api-key: "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" domain: "xxxxxx.cey2e.io" dnslogcn: domain: dnslog.cn alphalog: domain: dnslogxx.sh api_url: "http://dnslogxx.sh/" xray: x_token: "xraytest" domain: dnslogxx.sh api_url: "http://x.x.0.x:8777" revsuit: token: "xx" dns_domain: "log.xx.com" http_url: "http://x.x.x.x/log/" api_url: "http://x.x.x.x/helplog" ``` ### Curated PoCs Curated PoCs are an additional encrypted PoC set that can be mounted and updated automatically before scanning. - When `curated.enabled` is `auto` or `on`, afrog tries to mount curated PoCs on startup. - If a valid `endpoint` and `license_key` are configured, afrog will: - Log in to the curated service - Periodically check and download the latest curated PoCs - Decrypt and store them under `~/.config/afrog/pocs-curated` - PoC loading priority is: - curated > my > append > local > builtin so curated PoCs override other sources with the same PoC id. If `curated.enabled` is `off`, or `endpoint` is empty, afrog will not connect to any curated service and will only use local/builtin PoCs. For advanced users, you can override the curated PoC directory with the environment variable `AFROG_POCS_CURATED_DIR`. `reverse` is a reverse connection platform used to verify command execution vulnerabilities that cannot be echoed back. Currently, only ceye can be used for verification. ### Ceye Configuration - Go to the [ceye.io](http://ceye.io/) website and register an account. - Log in and go to the personal settings page. - Copy the `domain` and `api-key` and correctly configure them in the `afrog-config.yaml` file. ### Dnslogcn No configuration required, but unstable [dnslog.cn](http://dnslog.cn/) ### Alphalog Need to build services [alphalog](https://github.com/AlphabugX/Alphalog) ### Xray Need to build services [xray](https://docs.xray.cool/tools/xray/advanced/reverse) ### Revsuit Need to build services [Revsuit](https://github.com/Li4n0/revsuit)、 [Tutorial](https://mp.weixin.qq.com/s/hGwcMz8sh7BImBjI3wHqnQ) ## Json Output (For developers) ### Json Optional command: `-json` `-j`, Save the scan results to a JSON file. The JSON file includes the following contents by default: `target`, `fulltarget`, `id`, and `info`. The info field includes the following sub-fields: `name`, `author`, `severity`, `description`, and `reference`. If you want to save both `request` and `response` contents, please use the [-json-all](#jsonall) command parameter. ```sh afrog -t https://example.com -json result.json afrog -t https://example.com -j result.json ``` ### Warning The content of the JSON file is updated in real time. However, there is an important note to keep in mind: before the scan is completed, if developers want to parse the file content, they need to add a '`]`' symbol to the end of the file by themselves, otherwise it will cause parsing errors. Of course, if you wait for the scan to complete before parsing the file, this issue will not occur. ### JsonAll Optional command: `-json-all` `-ja`, The only difference between the `-json-all` and `-json` commands is that `-json-all` writes all vulnerability results, including `request` and `response`, to a JSON file. ```sh afrog -t https://example.com -json-all result.json afrog -t https://example.com -ja result.json ``` ## Screenshot ![](https://github.com/zan8in/afrog/blob/main/images/1.png) ## As Library ### Simple Example For comprehensive SDK documentation: - [SDK Usage Guide (English)](docs/SDK_Usage_Guide_English.md) - [SDK使用指南 (中文)](docs/SDK使用指南_中文.md) ### More Examples & Documentation - [Basic scanner](examples/basic_scan/main.go) - [Async scanner](examples/async_scan/main.go) - [OOB scanner](examples/oob_scan/main.go) - [Progress scanner](examples/progress_scan/main.go) - [SDK PortScan (sync/async)](examples/sdk_portscan/main.go) ## Discussion group To join the afrog communication group on WeChat, please first add the afrog personal account and mark it as **afrog**.
