Cacti through 1.2.7 is affected by a graphs.php?template_id= SQL injection vulnerability affecting how template identifiers are handled when a string and id composite value are used to identify the template type and id. An authenticated attacker can exploit this to extract data from the database, or an unauthenticated remote attacker could exploit this via Cross-Site Request Forgery.
Cacti 1.2.8 has stored XSS in data_sources.php, color_templates_item.php, graphs.php, graph_items.php, lib/api_automation.php, user_admin.php, and user_group_admin.php, as demonstrated by the description parameter in data_sources.php (a raw string from the database that is displayed by $header to trigger the XSS).
Cacti through 1.2.7 is affected by multiple instances of lib/functions.php unsafe deserialization of user-controlled data to populate arrays. An authenticated attacker could use this to influence object data values and control actions taken by Cacti or potentially cause memory corruption in the PHP module.
In Cacti through 1.2.6, authenticated users may bypass authorization checks (for viewing a graph) via a direct graph_json.php request with a modified local_graph_id parameter.
In clearFilter() in utilities.php in Cacti before 1.2.3, no escaping occurs before printing out the value of the SNMP community string (SNMP Options) in the View poller cache, leading to XSS.
A cross-site scripting (XSS) vulnerability exists in color_templates.php in Cacti before 1.2.0 due to lack of escaping of unintended characters in the Name field for a Color.
A cross-site scripting (XSS) vulnerability exists in pollers.php in Cacti before 1.2.0 due to lack of escaping of unintended characters in the Website Hostname for Data Collectors.
A cross-site scripting (XSS) vulnerability exists in graph_templates.php in Cacti before 1.2.0 due to lack of escaping of unintended characters in the Graph Vertical Label.
A cross-site scripting (XSS) vulnerability exists in host.php (via tree.php) in Cacti before 1.2.0 due to lack of escaping of unintended characters in the Website Hostname field for Devices.
