Summary

The Canto plugin for WordPress contains a Remote File Inclusion vulnerability that affects versions up to 3.0.4. This vulnerability arises from improper handling of the 'wp_abspath' parameter, which potentially allows unauthenticated attackers to execute arbitrary remote code when the server's allow_url_include directive is enabled. While local file inclusion could also be exploited, it presents a lower risk as it requires the attacker to upload a malicious PHP file via FTP or another method, placing it in a directory accessible by the web server.

Affected Version(s)

Canto * <= 3.0.4

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
