Intermediate Windows box where a guessable password-reset reminder on a Rails quiz app leads to a SQL injection file write RCE, and insecure folder permissions in BarracudaDrive 6.5 escalate to SYSTEM.
Intermediate Linux box running SeaCMS behind a randomized admin slug, where FTP logs leak both the slug and an LFI or SQLi path to the same SSH credential, then a cron job that blindly swaps binaries in /bin combined with a sudo NOPASSWD rule plants a SUID shell as root.
Easy Windows box where an X-Forwarded-For header bypasses an IP allowlist to reach a UNION-based SQL injection, leaking a user's password, then a Windows Sticky Notes database exposes the Administrator's password in plain text.
Intermediate Linux box running rConfig 3.9.4, chaining an unauthenticated SQL injection with a cracked admin hash and an authenticated RCE for a shell, then escalated to root through a SUID find binary.
Intermediate Linux box where a SQL injection bypasses a Prison Management System login for an upload-filter bypass RCE, then a reused database password and a tunneled Jenkins CVE chain for root.
Intermediate Linux box running WordPress with the vulnerable wp-advanced-search plugin, exploited via CVE-2024-9796 unauthenticated SQLi to crack a password hash, then a reused database password for SSH, and a SUID binary's shared library dlopen hijack via a world-writable home directory for root.
Easy Linux box with a book store web app vulnerable to SQL injection and default admin credentials, used to upload a PHP reverse shell for a www-data shell. A password file gives SSH access as tony, whose sudo rights include GTFOBins-exploitable binaries like pkexec for root.
Easy Linux box with an injectable GraphQL searchTerm over SQLite, used to dump and crack user hashes for SSH access as jane. A sudo-runnable pass-gen binary writes to /etc/shadow without stripping newlines, so a newline injection adds an account that reaches the shadow group and cracks the root hash.
Easy Linux box where default Nextcloud credentials expose the Issue Tracker source, revealing a SQL injection. A phpinfo page shows the server runs as root from /srv/http, so an INTO OUTFILE webshell gives code execution as root with no privilege escalation.
Easy Linux box running ZoneMinder v1.29.0, exploited through a SQL injection in the limit parameter. The database runs as root, so sqlmap's os-shell injects a UDF and executes commands as root directly, with no separate privilege escalation.
Intermediate Linux box exploiting a UNION-based SQL injection to dump credentials, reused against the Cockpit panel on port 9090 for a shell as james, then abusing a wildcard cp bug in a custom SUID binary to copy a setuid bash and gain root.
Exploiting Nagios XI via authenticated RCE CVE-2019-15949, then escalating privileges using sudo rights to gain root on Linux.
Compromise a Linux machine via LFI to log poisoning through SSH, escalate using MySQL running as root to write a SUID shell.
Linux box rooted via SQLi authentication bypass in Subrion CMS, exploiting a file upload vulnerability to gain RCE, then leveraging a cronjob for privilege escalation.
SQL injection reveals creds, port knocking opens SSH, password spraying via knockd leads to root through sudo abuse on a Linux target.
