Multiple vulnerabilities in extension "pixx.io integration for TYPO3 (DAM)" (pixxio)

The extension fails to restrict the image download to the configured pixx.io DAM URL resulting in Server-side request forgery. As a result of the Server-side request forgery vulnerability, an attacker can download various content from a remote location and save it to a user controlled filename which may result in Remote Code Execution. A TYPO3 backend user account is required to exploit both vulnerabilities.
