Intermediate Linux box exploiting CVE-2022-35914 in an exposed htmLawed test page for a www-data shell, then escalating to root via a writable cron script.
Intermediate Linux box where a Rails mass assignment flaw bypasses email confirmation, a file manager's local file inclusion plants an SSH key for a foothold, and a root private key left in a user's home directory gives privilege escalation.
Intermediate Windows box where anonymous FTP enumeration and a brute-forced default admin password expose a cracked web credential, used to trigger an uploaded PHP reverse shell; a public Task Scheduler privilege escalation exploit then creates a local administrator account.
Intermediate Windows box where a guessed Sonatype Nexus Repository Manager login leads to an authenticated remote code execution exploit, and the unpatched SMBGhost (CVE-2020-0796) SMBv3 kernel exploit then escalates to SYSTEM.
Intermediate Windows box running XAMPP, where a LibreOffice macro embedded in an uploaded ODT file gives a shell, a PHP webshell dropped into the Apache web root lands execution as the Apache service account, and GodPotato abuses its SeImpersonatePrivilege for a SYSTEM shell.
Hard Windows box where a malicious ODT upload leaks a NetNTLM hash that cracks to valid credentials, exposing a writable SMB share mapped to the web root for a PHP shell; a passwordless local MySQL running as SYSTEM then writes a DLL into System32 for a WerTrigger DLL-hijack SYSTEM shell.
Intermediate Windows box where an unauthenticated directory traversal in Argus Surveillance DVR leaks an SSH private key for initial access, then the same traversal exposes a custom-encoded Administrator password that is decoded and reused via runas for an Administrator shell.
Intermediate Linux box where a world-browsable admin logs directory leaks a user's password, and a SUID Serv-U FTP Server binary gives a known local privilege escalation straight to root.
Hard Linux box where a default-credential FTP brute force yields a PCAP that reveals a hidden upload endpoint, exploited via the ExifTool CVE-2021-22204 RCE, then escalated to root with PwnKit (CVE-2021-4034).
Intermediate Linux box using Grafana's CVE-2021-43798 directory traversal to leak and decrypt a Prometheus data source password for SSH access, then abusing disk group membership to read root's SSH key off the raw block device.
Intermediate Linux box where File Browser's default credentials and an enabled shell feature give command execution, an uploaded SSH key gives a foothold as david, and a SUID aa-exec binary gives root through GTFOBins.
Intermediate Windows box where an unauthenticated H2 database console gives remote code execution through a JNI DLL write, and SeImpersonatePrivilege is escalated to SYSTEM with GodPotato.
Intermediate Linux box running Jorani v1.0.0, exploited via the unauthenticated CVE-2023-26469 log-poisoning RCE for a user shell, then escalated to root through a passwordless sudo rule on env.
Intermediate Linux box where a Spring Boot API leaks every user's password in plaintext for SSH access, then escalated to root by pushing a malicious script into a git repo a root cron job pulls and executes.
Intermediate Linux box exploiting CVE-2023-34152, an ImageMagick filename command injection, for a www-data shell, then escalating to root through a SUID strace binary.
Intermediate Linux box where a Werkzeug API's /verify endpoint evaluates raw Python for a shell as cmeeks, then a writable systemd service file combined with a passwordless sudo reboot rule respawns that shell as root.
Intermediate Windows box where a password leaked in an employee page's role field unlocks IMAP mail, a LibreOffice macro phishing email delivered over SMTP gives a user shell, and a writable VeyonService binary escalates to SYSTEM.
Intermediate Windows box where a GlassFish directory traversal leaks SynaMan SMTP credentials reused for RDP access, then a TotalAV antivirus quarantine bypass using a directory junction plants a malicious DLL for a SYSTEM shell.
Intermediate Linux box chaining a rogue-MySQL config leak and cracked admin hash into MantisBT's dot_tool command injection for a shell, then escalating to root via a cron-leaked database password reused on a sudo-ALL account.
Intermediate Linux box exploiting a public LimeSurvey plugin RCE on a hidden vhost with default credentials, then chaining a leaked config password and a symlink-abused sudo rule to reach a second, fully privileged account.
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.
Easy Windows box where an unauthenticated Remote Mouse 3.008 RCE gives a user shell, a base64-encoded saved FileZilla password gives RDP access, and a Remote Mouse file-dialog trick (CVE-2021-35448) escalates to Administrator.
Easy Windows box where a hint-guessed CMS admin password leaks database hashes, and cracking a user's hash leads to RDP access, then a writable XAMPP config hijack (CVE-2020-11107) escalates to Administrator.
Intermediate Linux box where default PostgreSQL credentials and COPY FROM PROGRAM give a postgres shell, then a SUID find binary escalates to root.
