Summary
The Webinfos WordPress plugin through 1.2 does not validate the type or name of uploaded files, nor restrict the upload action with any authentication, capability, or nonce check, allowing unauthenticated attackers to upload arbitrary files (including PHP) to a web-accessible directory, leading to remote code execution on servers that execute PHP from the uploads path.
