PentesterAcademy Vulnerable Servers II Lab Write-Up | metasploit-pivoting Lab Link : https://attackdefense.pentesteracademy.com/challengedetails?cid=1747 Vulnerable Servers II is a lab from PentesterAcademy, which is rated as easy. The lab topology shows two machines which means, there are two targets and the attacker has to perform pivoting in order to hack and get the flag from the target machine. First Select the nearest Server and Click on Run the lab. Once the lab is up, a web based terminal will be opened in the Web Browser. Firstly, check the IP address of the attacking machine. We can see that, there are two interfaces. And as per the instructions, the first target machine should be 192.17.147.3. Let’s perform an Nmap scan of the target. The scan result shows that TCP port 8080 is open and is running an Apache Tomcat webserver/Coyote JSP engine 1.1. Let’s try to connect the webserver using netcat. We can see that the Webserver is running OpenKM, a Document
Modular Policy Framework (MPF) configuration defines set of rules for applying firewall features, such as traffic inspection, QoS etc. to the traffic transiting the firewall
There are 3 main components in creating a MPF.
1) Class Map
Class map is used to identify the type of traffic. This can be done by creating an ACL.
2) Policy Map
Policy Map specifies what action the ASA should take against the traffic identified by the Class Map.
3) Service Policy
Finally Service policy specifies where to apply it. The policy is applied to an interface or Globally.

access-list OUTSIDE-TO-INSIDE permit tcp any any eq ftp
<--- The above ACL will allow FTP traffic. This ACL can be different than the Interface ACL--->
class-map FTP-CLASS-MAP
match access-list OUTSIDE-TO-INSIDE
<--- The class map FTP-CLASS-MAP will look for the FTP traffic based on ACL --->
policy-map FTP-POLICY-MAP
class FTP-CLASS-MAP
inspect ftp
<--- What action need to be done? here inspect the ftp. --->
service-policy FTP-POLICY-MAP interface outside
<--- Apply the policy in the outside interface --->
The above illustration is just an example. MPF enables the administrator to assign different network policies to different traffic flows in a flexible and granular manner.
