Descriptions

lib/TWiki/Sandbox.pm in TWiki 6.0.0 and earlier, when running on Windows, allows remote attackers to bypass intended access restrictions and upload files with restricted names via a null byte (%00) in a filename to bin/upload.cgi, as demonstrated using .htaccess to execute arbitrary code.

lib/TWiki/Sandbox.pm en TWiki 6.0.0 y anteriores, cuando se ejecuta en Windows, permite a atacantes remotos evadir las restricciones de acceso y subir ficheros con nombres restringidos a través un byte nulo (%00) en el nombre del fichero en bin/upload.cgi, como lo demuestra el uso de .htaccess para ejecutar código arbitrario.

Twiki versions 4.x, 5.x, and 6.0.0 suffer from a file upload bypass vulnerability.
