      "value": "Whistle is an HTTP, HTTP2, HTTPS, and WebSocket debugging proxy. Prior to 2.10.3, lib/service/service.js handles GET /cgi-bin/temp/get by reading req.query.filename, joining it to TEMP_FILES_PATH only when it matches the temporary file pattern, and otherwise passing the user-supplied filename directly to getFile, allowing a remote attacker to read arbitrary files such as /etc/passwd. This issue is reported as fixed in version 2.10.3."

Antes de la versión 2.10.3, lib/service/service.js maneja GET /cgi-bin/temp/get leyendo req.query.filename, uniéndolo a TEMP_FILES_PATH solo cuando coincide con el patrón de archivo temporal, y de lo contrario, pasando el nombre de archivo proporcionado por el usuario directamente a getFile, permitiendo a un atacante remoto leer archivos arbitrarios como /etc/p4ssd. Este problema se informa como solucionado en la versión 2.10.3."
