Hunt4Spring - A "Spring4Shell" vulnerability scanner.

项目说明

Hunt4Spring

Hunt4Spring helps with identifying as well as exploiting URLs which are potentially to C aka Spring4Shell.

Video Demo:

Usage

To use the tool, you can grab any one of the binaries from the releases section or build the source code yourself. The code is in Go, hence a simple go build will do the job, provided you have a working Go setup.

Flags

In order to run Hunt4Spring, users have two options a. Either they can provide a single URL using the -url flag or provide with bulk URLs through a file by using the -file flag.

You can specify the name of the file to store the output in JSON format by using the -outfile flag. [By default the output gets stored in a file called hunt4spring.json]

Usage Modes

#### Default Mode
In the default mode, user doesn't has to specify any additional flags and this mode would be used by the tool by default. The tool will look for all URL/URLs which are potentially to this .

We do not have to provide any additional flags in this case.

#### Exploit Mode
In the exploit mode, the tool would not just scan the URL/URLs but would even try to exploit them by placing a webshell in the target's root directory. The name of the webshell would be shell.jsp having the password hunt4spring.

In order to enable exploit mode, we have to provide an addtional flag (-exploit) along with the normal input flags:

Output

The output file saves the data in JSON format like below:

Setting up a Test En

If you'd like to test out Spring4Hunt or the Spring4Shell in general, then you can refer to this docker image: /spring-core-rce-2022-03-29.

The installation process is quite simple in this case as well, you just have to run the below command:

The app should now be a at .
