Furthermore we will use SFTP to bypass login restrictions and manipulate a python cache file to gain root privileges.https://wearethebug.dev/posts/vl-unintended/Thu, 25 Apr 2024 00:00:00 +0000https://wearethebug.dev/posts/vl-unintended/Unintended is an Medium chain that provides a hands-on experience with common missteps in Active Directory deployments, demonstrating how attackers can pivot between services to escalate privileges. It blends Linux privilege escalation techniques with Active Directory attack paths, making it a valuable practice ground for both offensive and defensive security practitioners.https://wearethebug.dev/posts/vl-store/Fri, 17 Feb 2023 00:00:00 +0000https://wearethebug.dev/posts/vl-store/Store is a Hard difficulty box that hosts a Node.js web application, allowing file uploads and storage. The app is vulnerable to Arbitrary File Read, which lets us read configuration files and recover SFTP credentials. We can also dump the host’s environment variables and discover the app was started with --inspect, with the Node inspector listening on port 9229. By abusing SFTP for port forwarding, we can tunnel that internal inspector port to our machine, attach and run JavaScript to spawn a reverse shell as user dev. For privilege escalation, the ChromeDriver service on port 9515 can be abused via its WebDriver API to execute a malicious script and gain a root shell.
