HTB Monitored Walkthrough

In this deep-dive walkthrough of the HTB Monitored machine, we move past basic TCP scans to master the art of professional enumeration and OSCP-style methodology. We start by discovering why you should never skip UDP enumeration, leveraging an SNMP misconfiguration to leak credentials hidden in plain sight within process arguments. From there, we explore a critical authentication bridge: bypassing a "disabled" GUI login by exploiting the Nagios XI API to generate a valid session token. This unlocks an authenticated SQL injection (CVE-2023-40931), giving us admin access. Finally, we cover multiple advanced Local Privilege Escalation (LPE) paths, proving that root isn't always about direct command injection—sometimes it's about abusing symlinks, rsyslog forwarding, and writable service binaries triggered by root-run backup scripts. #HackTheBox #NagiosXI #PenetrationTesting #OSCP #CyberSecurity
