HTB DevArea Complete Writeup - CVE-2022-46364 Apache CXF LFI & HoverFly RCE

DevArea is a Medium-difficulty HackTheBox machine from Season 10 featuring an internal developer platform exposed across multiple services. The exploitation chain begins with anonymous FTP access to a leaked JAR file, which reveals an Apache CXF SOAP service vulnerable to a critical XOP/MTOM Local File Inclusion (CVE-2022-46364 / CVE-2022-46363). Reading the HoverFly systemd service file leaks admin credentials, which are used to authenticate against the HoverFly Admin API and obtain a JWT token. From there, a malicious middleware payload injected via the /api/v2/hoverfly/middleware endpoint delivers a reverse shell as dev_ryan. Privilege escalation to root exploits a world-writable /bin/bash binary combined with a sudo-permitted script to plant a root-owned SUID shell. This writeup provides a complete step-by-step walkthrough with detailed technical analysis of each exploitation stage.

HTB Kobold Complete Writeup — CVE-2026-23744 MCP Inspector RCE & Docker Escape

Kobold is an Easy-difficulty HackTheBox machine from Season 10 built around modern AI tooling infrastructure. The attack chain begins with subdomain enumeration uncovering an MCPJam Inspector instance vulnerable to CVE-2026-23744 — a critical unauthenticated RCE in the /api/mcp/connect endpoint that allows arbitrary command execution via a crafted serverConfig payload. This delivers a reverse shell as the user ben. Privilege escalation exploits an implicit Docker group membership accessible via newgrp docker, which is leveraged to mount the host filesystem inside a root-running MySQL container and read the root flag directly — a textbook Docker socket escape. This writeup provides a complete step-by-step walkthrough with beginner-friendly explanations of each technique.

Facts Hack The Box Writeup-Sudo Privilege Escalation via Facter (Linux)

In this walkthrough of the Facts machine from Hack The Box, we exploit a misconfigured sudo rule allowing the execution of Facter as root. By abusing Facter's --custom-dir option, we load a malicious Ruby fact file that executes with UID 0. Instead of spawning an unstable shell, we apply the SetUID bit to /bin/bash, gaining a persistent root shell via bash -p. This writeup covers enumeration, attack reasoning, exploitation mechanics, and a clean privilege escalation path to root.
