Descriptions

An issue was discovered in Open-Xchange OX App Suite before 7.8.1-rev11. The content sanitizer component has an issue with filtering malicious content in case invalid HTML code is provided. In such cases the filter will output a unsanitized representation of the content. Malicious script code can be executed within a user's context. This can lead to session hijacking or triggering unwanted actions via the web interface (sending mail, deleting data etc.). Attackers can use this issue for filter evasion to inject script code later on.

Ha sido descubierto un problema en Open-Xchange OX App Suite en versiones anteriores a 7.8.1-rev11. El componente de desinfectante de contenido tiene un problema con el filtrado de contenido malicioso en caso de que un código HTML inválido sea provisto. En estos casos el filtro emitirá una representación del contenido no desinfectada. El código script malicioso puede ser ejecutado dentro de un contexto de usuario. Esto puede conducir al secuestro de sesión o desencadenamiento de acciones no deseadas a través de la interfaz web (enviando correos, borrando datos etc.). Los atacantes pueden utilizar este problema para evadir el filtro para inyectar código script más tarde.
