Directory traversal vulnerability in install05.php in Simple PHP Blog (SPB) 0.4.7.1 and earlier allows remote attackers to include and execute arbitrary local files via directory traversal sequences and a NUL (%00) character in the blog_language parameter, as demonstrated by injecting PHP sequences into an Apache access_log file, which is then included using install05.php.
