DescriptionThe Turnkey bbPress by WeaverTheme plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 1.7.1 via deserialization of untrusted input in the wvrbbp_set_to_serialized_values() function (reached through the wvrbbp_save_restore() settings-restore handler). The function reads the raw contents of an administrator-uploaded file and passes them directly to unserialize() without any validation. 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 plugin itself; however, if a POP chain is present via an additional plugin or theme installed on the target system, it could allow the attacker to delete arbitrary files, retrieve sensitive data, or execute code.
