Vulnerability Title
Ninja Forms <= 3.14.6 - Authenticated (Administrator+) PHP Object Injection via Form Import
来源: CVE Program / CVE List V5
Vulnerability Description
The Ninja Forms – The Contact Form Builder That Grows With You plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 3.14.6 via deserialization of untrusted input . This makes it possible for authenticated attackers, with administrator-level access and above, to inject a PHP Object. No known POP chain is present in the vulnerable software, which means this vulnerability has no impact unless another plugin or theme containing a POP chain is installed on the site. If a POP chain is present via an additional plugin or theme installed on the target system, it may allow the attacker to perform actions like delete arbitrary files, retrieve sensitive data, or execute code depending on the POP chain present. The deserialization is triggered automatically during form import when WPN_Helper::build_nf_cache() invokes $action->get_settings() immediately after the crafted form is imported, requiring no further interaction beyond the import action itself.
