Multiple vulnerabilities have been reported in Cacti, which can be exploited by malicious users to conduct script insertion attacks and by malicious people to conduct cross-site scripting and cross-site request forgery attacks.
1) Input passed to the "default_height" and "default_width" parameters in graph_settings.php is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
2) Input passed to the "num_columns" parameter in graph_settings.php is not properly sanitised before being used. This can be exploited to insert HTML and script code, which will be executed in a user's browser session in context of an affected site if malicious data is viewed.
3) The application allows users to perform certain actions via HTTP requests without performing proper validity checks to verify the requests. This can be exploited to e.g. log out a user when a logged-in user visits a specially crafted web page.
The vulnerabilities are reported in versions prior to 0.8.7i.
