This was an intermediate Linux machine that involved exploiting the ticket reply via email functionality of osTicket to access a MatterMost web application to find SSH credentials and using Hashcat rules to crack root hashes stored in the MySQL database to escalate privileges.
Read moreThis was an intermediate Linux machine that involved exploiting a remote code execution vulnerability in the CuteNews web application to gain initial access, exposed user password hashes to gain a user shell, and a vulnerability in the USBCreator D-Bus interface to escalate privileges to root.
Read moreThis was an intermediate Linux machine that involved exploiting a remote code execution in GitLab to gain initial access, an exposed root password and a misconfigured docker container to escalate privileges to root.
Read moreThis was an easy Windows machine that involved uploading a web.config file onto a Windows ASP web server to gain remote code execution and exploiting token impersonation to escalate privileges to system.
Read moreThis was an intermediate Linux box that involved exploiting an insecure AWS S3 bucket to upload a PHP reverse shell to gain remote access, using credentials found in an unprotected DynamoDB database to gain a user shell and exploiting a vulnerable PHP script to extract the root user’s private SSH keys and escalate privileges to root through the DynamoDB database.
Read moreThis was a fairly easy Linux box that involved exploiting a local file inclusion and remote code execution vulnerability in GitLab to gain remote access to the machine, obtaining administrative access to GitLab through the console to find a user’s private key and exploiting a PATH hijack vulnerability within a SUID script to escalate privileges to root.
Read moreThis was an intermediate Windows machine that involved crawling a username and password from a web application to access RPC, through which a password stored in a printer’s description can be found in order to obtain remote access to the box, and exploiting a known vulnerability with the SeLoadDriverPrivilege permission to escalate privileges to SYSTEM.
Read moreThis was an intermediate Linux machine that involved exploiting an SQL injection vulnerability to gain access to a traceroute page affected by a remote command vulnerability in order to obtain a reverse shell, and exploiting a PHP function used in a cron hob to gain root-level code execution and therefore a root shell.
Read moreThis was an easy Solaris machine that required enumerating users in the Finger service to identify the sunny user, bruteforcing it with Hydra to authenticate via SSH, cracking a user hash found in a backup folder to escalate to the sammy user and exploiting the SUID permission set against Wget to escalate privileges to root.
Read moreThis was a fairly easy Linux box that involved exploiting an arbitrary file upload vulnerability in the My Image plugin of the Nibbleblog web application in order to upload a reverse shell, and a script with sudo permissions allowed to escalate privileges to root.
