CCN-162900

Published:2019-06-25
Updated:2019-06-25
Summary:Typo3 CMS could allow a remote authenticated attacker to traverse directories on the system, caused by improper validation of user-supplied input by the Backend API configuration. An attacker could send a specially-crafted request to tsconfig_includes field containing "dot dot" sequences (/../) to execute arbitrary code on the system.
