Description
Joomla Extension - yootheme.com - Unauthenticated remote code execution in YOOtheme Pro 5.0.0-5.0.52 - YOOtheme Pro’s publicly accessible image transformation handler incompletely binds normalized image operations and the output destination to its request signature. An unauthenticated remote attacker can reuse a signature disclosed in a legitimate public image URL, inject additional image operations, traverse out of the intended cache directory, and write an attacker-controlled PNG/PHP polyglot to an executable public media directory.
