## Technical details

The Balbooa Forms extension for Joomla is vulnerable to an unrestricted file upload (CWE-434). The flaw exists because the component fails to properly validate or restrict the types of files uploaded by users. An unauthenticated remote attacker can exploit this by sending a specially crafted request to upload executable scripts (such as PHP files) to the server. Once uploaded, these files can be executed to achieve full Remote Code Execution (RCE) with the privileges of the web server. The vulnerability is reportedly being exploited in the wild.
