TryHackMe Plotted-EMR（Free Room): Cron Wildcard Injection & Privilege Escalation with Capabilities

#pentesting #ethicalhacking #cybersecurity In this video, I walk through a complete exploitation chain of OpenEMR 5.0.1, starting from directory enumeration and ending with full root privilege escalation. We begin by using Gobuster to discover hidden directories on a non-standard port, which leads us to an exposed OpenEMR login portal. Due to improper cleanup, sensitive installation files like /setup.php and /admin.php are publicly accessible, resulting in critical information disclosure. By abusing the exposed setup functionality, we create a new OpenEMR site and gain administrator access. This allows us to exploit a known OpenEMR 5.0.1 Remote Code Execution (RCE) vulnerability using Searchsploit, ultimately landing a reverse shell as www-data. From there, we perform privilege escalation by: Identifying a misconfigured cronjob Exploiting rsync wildcard injection Creating a SUID bash shell Escalating from www-data → plot_admin → root We also analyze Linux capabilities (cap_fowner+ep) and demonstrate how Perl can be abused to modify file permissions and obtain root access. This video is ideal for: TryHackMe & VulnHub learners OSCP / PNPT / CEH preparation Anyone learning Linux privilege escalation Pentesters and red teamers 🧠 Techniques Covered Directory & file enumeration (Gobuster) OpenEMR misconfiguration abuse Information disclosure via setup.php OpenEMR RCE exploitation Reverse shell with Netcat Cronjob wildcard injection SUID shell abuse Linux capabilities exploitation Privilege escalation to root ⚠️ Disclaimer: This content is for educational purposes only.
