SQL injection vulnerability in templates_export.php in Cacti 0.8.7e and earlier allows remote attackers to execute arbitrary SQL commands via the export_item_id parameter.

Cacti 0.8.7e and earlier allows remote authenticated administrators to gain privileges by modifying the "Data Input Method" for the "Linux - Get Memory Usage" setting to contain arbitrary commands.

Multiple SQL injection vulnerabilities in Cacti 0.8.7 before 0.8.7b and 0.8.6 before 0.8.6k allow remote authenticated users to execute arbitrary SQL commands via the (1) graph_list parameter to graph_view.php, (2) leaf_id and id parameters to tree.php, (3) local_graph_id parameter to graph_xport.php, and (4) login_username parameter to index.php/login.

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.

Cacti 0.8.6e and earlier does not perform proper input validation to protect against common attacks, which allows remote attackers to execute arbitrary commands or SQL by sending a legitimate value in a POST request or cookie, then specifying the attack string in the URL, which causes the get_request_var function to return the wrong value in the $_REQUEST variable, which is cleansed while the original malicious $_GET value remains unmodified, as demonstrated in (1) graph_image.php and (2) graph.php.

config.php in Cacti 0.8.6e and earlier allows remote attackers to set the no_http_headers switch, then modify session information to gain privileges and disable the use of addslashes to conduct SQL injection attacks.

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.

PHP remote file inclusion vulnerability in config_settings.php in Cacti before 0.8.6e allows remote attackers to execute arbitrary PHP code via the config[include_path] parameter.
