In Beyond Root, a look at SeLinux and how it blocked things I tried to do on Pit. From there, I’ll find that I can write scripts that will be run by SNMP, and I’ll use that to get execution and a shell as root. I’m not able to get a reverse shell because of SeLinux, but I can enumerate enough to find a password for michelle, and use that to get access to a Cockpit instance which offers a terminal. First, I’ll enumerate it to leak the location of a webserver running SeedDMS, where I’ll abuse a webshell upload vulnerability to get RCE on the host. In Beyond Root, I’ll look at the webserver config, and find the error in the public Jarm code that allowed me to use Jarm as a port scanner.Ĭtf htb-pit hackthebox centos nmap udp snmp feroxbuster snmpwalk seeddms cve-2019-12744 exploitdb webshell upload selinux cockpit htb-sneaky I’ll need to create a malicious server as well, and I’ll show two ways, using IPTables and a custom Metasploit module. To exploit this, I’ll find a POC and convert it into a Gopher redirect by redirecting the GET request. Given that Jarmis is a Linux host, it’s odd, and it turns out that this is the same port that OMI listens to, and the host is vulnerable to OMIGod. I’ll abuse that service to get a list of open ports on localhost and find 5985/5986, which are typically WinRM. There’s an application that will scan a given server and report back the Jarm signature, and if that signature matches something potentially malicious in the database, it will do a GET request to that server to collect additional metadata. My favorite part about Jarmis was that it is centered around this really neat technology used to fingerprint and identify TLS servers.
