HackTheBox - Conversor
A Linux machine where an XSLT stylesheet processor accepts attacker-controlled input — and the ability to write arbitrary files, combined with a scheduled task and a vulnerable system utility, leads to root.
HackTheBox - Eighteen
A Windows domain controller where SQL Server impersonation exposes a cracked hash — and a recently disclosed Active Directory attack against delegated service accounts enables a complete domain takeover.
HackTheBox - Interpreter
A healthcare integration platform exposes an unpatched RCE, but cracking a non-standard password scheme is only the halfway point — getting to root means finding the flaw hidden inside a server that claims to be safe.
HackTheBox - GoodGames
A Linux machine where weak database security and an internal admin panel lead to a foothold, with a creative Docker escape to reach the host as root.
HackTheBox - Help
A Linux machine where a help desk application’s unauthenticated GraphQL endpoint exposes user credentials — and an authenticated SQL injection, combined with an older kernel vulnerability, escalates to root.
HackTheBox - Curling
A Linux machine running a Joomla site where a hint hidden in the page source leads to credentials — and a password buried under layers of nested compression unlocks a path to a higher-privilege user.
HackTheBox - Shocker
A Linux machine where directory enumeration uncovers a CGI script in an exposed cgi-bin directory — and a classic Bash vulnerability allows injecting commands through a crafted HTTP header.
HackTheBox - Valentine
A Linux machine named after its core vulnerability — a memory disclosure flaw in OpenSSL leaks just enough data to decrypt an encrypted RSA key found hiding in the web server’s directory listing.
HackTheBox - Access
A Windows machine where anonymous FTP access begins a credential chain — through a database file, an email archive, and a telnet session — ending with stored administrator credentials ready to leverage.
