CRLF injection vulnerability in Cacti 0.8.7 before 0.8.7b and 0.8.6 before 0.8.6k, when running on older PHP interpreters, allows remote attackers to inject arbitrary HTTP headers and conduct HTTP response splitting attacks via unspecified vectors.

Multiple cross-site scripting (XSS) vulnerabilities in Cacti 0.8.7 before 0.8.7b and 0.8.6 before 0.8.6k allow remote attackers to inject arbitrary web script or HTML via (1) the view_type parameter to graph.php; (2) the filter parameter to graph_view.php; (3) the action parameter to the draw_navigation_text function in lib/functions.php, reachable through index.php (aka the login page) or data_input.php; or (4) the login_username parameter to index.php.

PHP file inclusion vulnerability in top_graph_header.php in Cacti 0.8.6d and possibly earlier versions allows remote attackers to execute arbitrary PHP code via the config[library_path] parameter.
