React2Shell (CVE-2025-55182 / CVE-2025-66478) vulnerability lab - Learn to detect and exploit vulnerable Next.js applications

Vulnerability scanning identifies security weaknesses, misconfigurations, and known vulnerabilities in systems and services.

Identifying security weaknesses and CVEs

Service enumeration gathers detailed information about running services, including versions and configurations, to identify weaknesses and viable attack paths.

Methods for discovering open ports

Techniques for identifying active systems.

This is a walkthrough of the Mr. Robot themed Vulnhub box, located here: https://www.vulnhub.com/entry/mr-robot-1,151/

A medium CTF challenge that demonstrates a PHP Cookie Serialization Attack via preferences.php, leading to a reverse shell. Discover how the .Xauthority file was exploited to capture sensitive data, and learn about privilege escalation techniques used to gain root access without a password.

Photographer contains multiple exploits and misconfigurations. Starting with retrieving credentials from Samba shares then exploiting Koken CMS to gain a reverse shell. LinPEAS revealed MySQL credentials and a SUID PHP binary, enabling privilege escalation to root.

This box is exploited using OpenSSL's predictable PRNG to brute-force an SSH key, gaining access as another user. A sudo misconfiguration is then used to modify /etc/passwd, adding a root user, allowing privilege escalation and capturing the final flag.

Ephemeral 2 is a medium-level box involving Samba exploitation, reverse shells, and privilege escalation. Key steps include discovering open ports, brute-forcing SMB credentials, exploiting a "magic script," and leveraging cron jobs and writable profile scripts to gain root access..

The "Corrosion: 1" CTF involved exploiting log poisoning and path abuse for remote command execution and privilege escalation. Key steps included cracking a ZIP file password and exploiting a vulnerable script to gain root access, culminating in the capture of the root flag.

Vulnhub's Web Machine N7. Labeled as a medium difficulty box with a lot of directory enumeration and some use of sqlmap

Walkthrough of Corrosion 2 vulnhub box. This is considered to be a medium level that involves zip file password cracking and RCE via tomcat protocol.

A walkthrough of VulnHub's Matrix: 2 box. It is an intermediate challenge with directory traversal, password cracking and steganography.

A walkthrough of vulnhub's Matrix: 1 box. It is an intermediate box that involves brute force and breaking out of a restricted shell.
