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
