Descriptions

Silverpeas 5.15 through 6.0.2 is affected by an authenticated Directory Traversal vulnerability that can be triggered during file uploads because core/webapi/upload/FileUploadData.java mishandles a StringUtil.java call. This vulnerability enables regular users to write arbitrary files on the underlying system with privileges of the user running the application. Especially, an attacker may leverage the vulnerability to write an executable JSP file in an exposed web directory to execute commands on the underlying system.

Silverpeas versión 5.15 hasta 6.0.2 se ve afectada por una vulnerabilidad autenticada de Directory Traversal que puede activarse durante la carga de archivos porque core/webapi/upload/FileUploadData.java maneja de manera inapropiada una llamada StringUtil.java. Esta vulnerabilidad permite a los usuarios regulares escribir archivos arbitrarios en el sistema subyacente con privilegios del usuario que ejecuta la aplicación. Especialmente, un atacante puede atacar la vulnerabilidad para escribir un archivo JSP ejecutable en un directorio web expuesto para ejecutar comandos en el sistema subyacente.
