An attacker can exploit this vulnerability to upload arbitrary code and run it in the context of the webserver process. This may facilitate unauthorized access or privilege escalation; other attacks are also possible. WordPress Plugin Webapp builder (Free mobile apps native iPhone iOS & Android Winphone mobile apps) version 2.0 is vulnerable; prior versions may also be affected.
Remediation
