Descriptions

Plone CMS until version 5.2.4 has a stored Cross-Site Scripting (XSS) vulnerability in the user fullname property and the file upload functionality. The user's input data is not properly encoded when being echoed back to the user. This data can be interpreted as executable code by the browser and allows an attacker to execute JavaScript in the context of the victim's browser if the victim opens a vulnerable page containing an XSS payload.

Plone CMS hasta versión 5.2.4 presenta una vulnerabilidad de tipo Cross-Site Scripting (XSS) almacenada en la propiedad de nombre completo del usuario y en la funcionalidad file upload. Los datos de entrada del usuario no están codificados correctamente cuando son devueltos al usuario. El navegador puede interpretar estos datos como un código ejecutable y permite a un atacante ejecutar JavaScript en el contexto del navegador de la víctima si la víctima abre una página vulnerable que contiene una carga útil de tipo XSS
