Title
DataEase vulnerable to stored cross-site scripting via file upload bypass
Summary
DataEase is a data visualization and analytics platform. In DataEase versions through 2.10.13, a stored cross-site scripting vulnerability exists due to improper file upload validation and authentication bypass. The StaticResourceApi interface defines a route upload/{fileId} that uses a URL path parameter where both the filename and extension of uploaded files are controllable by users. During permission validation, the TokenFilter invokes the WhitelistUtils#match method to determine if the URL path is in the allowlist. If the requestURI ends with .js or similar extensions, it is directly deemed safe and bypasses permission checks. This allows an attacker to access "upload/1.js" while specifying arbitrary file extensions, enabling the upload of HTML files containing malicious JavaScript. The vulnerability is fixed in version 2.10.14. No known workarounds exist.

"value": "DataEase es una plataforma de visualizaci\u00f3n y an\u00e1lisis de datos. En las versiones de DataEase hasta la 2.10.13, existe una vulnerabilidad de cross-site scripting almacenado debido a una validaci\u00f3n de carga de archivos inadecuada y a una omisi\u00f3n de autenticaci\u00f3n. La interfaz StaticResourceApi define una ruta upload/{fileId} que utiliza un par\u00e1metro de ruta URL donde tanto el nombre de archivo como la extensi\u00f3n de los archivos cargados son controlables por los usuarios. Durante la validaci\u00f3n de permisos, el TokenFilter invoca el m\u00e9todo WhitelistUtils#match para determinar si la ruta URL est\u00e1 en la lista de permitidos. Si la requestURI termina con .js o extensiones similares, se considera directamente segura y omite las comprobaciones de permisos. Esto permite a un atacante acceder a \u0027upload/1.js\u0027 mientras especifica extensiones de archivo arbitrarias, lo que permite la carga de archivos HTML que contienen JavaScript malicioso. La vulnerabilidad se corrige en la versi\u00f3n 2.10.14. No existen soluciones alternativas conocidas."
