Product | Affected Versions<\/p>\n

Forminator Forms Plugin for WordPress | Up to and including 1.44.2<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The vulnerability exists due to the unsafe deserialization of untrusted input in the ‘entry_delete_upload_files’ function. An attacker can exploit this by injecting a malicious PHP Object through a PHAR file. The deserialization occurs when a form submission is deleted, either by an Administrator or via auto-deletion determined by plugin settings. If a PHP Object-Oriented Programming (POP) chain is present in an additional plugin or theme installed on the target system, arbitrary actions such as file deletion, sensitive data retrieval, or code execution could be performed depending on the POP chain present.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

The following is a conceptual example of how the vulnerability might be exploited. This is a sample HTTP request with a malicious payload.<\/p>\n

POST \/forminator_forms\/delete HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/php\n{ \"entry_delete_upload_files\": \"phar:\/\/path\/to\/malicious\/file.phar\" }<\/code><\/pre>\n
Mitigation<\/strong><\/p>\n
Users are advised to apply the vendor patch immediately. For temporary mitigation, users can employ a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) to monitor and block suspicious activities. However, these measures only offer temporary relief and do not address the root cause of the vulnerability.<\/p>\n","protected":false},"excerpt":{"rendered":"
