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.

graph.php in Cacti 0.8.7 before 0.8.7b and 0.8.6 before 0.8.6k allows remote attackers to obtain the full path via an invalid local_graph_id parameter and other 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.
