CVE-2009-4488
Estado: ModificadaCrítica (9.8)—
Varnish 2.0.6 writes data to a log file without sanitizing non-printable characters, which might allow remote attackers to modify a window's title, or possibly execute arbitrary commands or overwrite files, via an HTTP request containing an escape sequence for a terminal emulator. NOTE: the vendor disputes the significance of this report, stating that "This is not a security problem in Varnish or any other piece of software which writes a logfile. The real problem is the mistaken belief that you can cat(1) a random logfile to your terminal safely.

NOTA: el fabricante cuentiona el significado de este informe, alegando que \"esto no es un problema de seguridad en Varnish o cualquier elemento de software que escribe en el archivo de log. El problema real es la falsa creencia de que se puede ejecutar el comando \"cat\" de manera segura sobre un archivo de logs aleatorio en la consola\"."
