PHP remote file inclusion vulnerability in template.class.php in Carbonize Lazarus Guestbook before 1.7.3 allows remote attackers to execute arbitrary PHP code via a URL in the include_path parameter to admin.php, probably due to a dynamic variable evaluation vulnerability.

Multiple cross-site scripting (XSS) vulnerabilities in Carbonize Lazarus Guestbook 1.6 and earlier allow remote attackers to inject arbitrary web script or HTML via (1) the show parameter in codes-english.php and (2) the img parameter in picture.php, after the name of an existing file.
