Multiple directory traversal vulnerabilities in Simple PHP Blog (SPHPBlog), probably 0.4.8, allow remote attackers to read arbitrary files and possibly include arbitrary PHP code via a .. (dot dot) sequence in the blog_theme parameter in (1) index.php, (2) add_cgi.php, (3) add_link.php, (4) login.php, (5) template.php, or (6) contact.php.
