Researcher Richard Telleng (stueotue)


The Advanced Database Cleaner plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 3.1.3 via deserialization of untrusted input in the 'process_bulk_action' function. This makes it possible for authenticated attacker, with administrator access and above, to inject a PHP Object. No POP chain is present in the vulnerable plugin. 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.
