PHP remote file inclusion vulnerability in functions/update.php in Cicoandcico CcMail 1.0 allows remote attackers to execute arbitrary PHP code via a URL in the functions_dir parameter.

Cicoandcico CcMail 1.0.1 and earlier does not verify that the this_cookie cookie corresponds to an authenticated session, which allows remote attackers to obtain access to the "admin area" via a modified this_cookie cookie.
