Root falls to a Python .pth injection via a group-writable plugin directory, abused through a passwordless sudo misconfiguration to spawn a SUID shell and fully compromise the box.https://wearethebug.dev/posts/vl-down/Fri, 20 Sep 2024 00:00:00 +0000https://wearethebug.dev/posts/vl-down/Down is an easy-rated Linux machine that involves exploiting an arbitrary file read by bypassing a protocol-based filter to discover the source code of the running PHP web app, eventually, a remote code execution to gain an initial foothold. The attacker finds a readable pswm encrypted file in the user's home directory. The pwsm uses Python's cryptocode module and a master password to encrypt and decrypt the data. The attacker is supposed to write a small script to decrypt the blob and compromise the user. The compromised user is a member of the sudo group, allowing the user to escalate and obtain root access.https://wearethebug.dev/posts/vl-manage/Fri, 28 Jun 2024 00:00:00 +0000https://wearethebug.dev/posts/vl-manage/Manage is an easy Linux machine that features an exposed Java RMI service. Exploiting the underlying vulnerable JMX service leads to remote code execution and gaining a remote shell as the tomcat user. Lateral movement to the useradmin account can be achieved by discovering a misconfigured backup archive which leaks sensitive files, including SSH keys and OTP codes. Finally, a sudo misconfiguration allows for creating a privileged user and achieving full privilege escalation.https://wearethebug.dev/posts/vl-tengu/Thu, 28 Mar 2024 00:00:00 +0000https://wearethebug.dev/posts/vl-tengu/Tengu is a medium-rated chained machine on VulnLab, features a mixed environment with two Windows hosts and one Linux host. Exploiting Node-RED on Linux (with MSSQL) grants command execution, decrypts service passwords, and pivots to dump NTLM hash. Constrained delegation allows impersonating MSSQL admin for local admin access then recover Domain Admin credentials via DPAPI and Kerberos to compromise the Domain Controller (DC).https://wearethebug.dev/posts/vl-reset/Wed, 07 Feb 2024 00:00:00 +0000https://wearethebug.dev/posts/vl-reset/Reset is an Easy difficulty Linux machine which showcases abusing a password reset functionality in a web application following a log poisoning attack, to achieve Remote Code Execution. For privilege escalation, Rservices are abused, then a detached tmux session is used to abuse sudo privileges on nano text editor and execute commands as the root user.
