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.
Cacti before 1.1.37 has XSS because the get_current_page function in lib/functions.php relies on $_SERVER['PHP_SELF'] instead of $_SERVER['SCRIPT_NAME'] to determine a page name.
Cacti before 1.1.37 has XSS because it does not properly reject unintended characters, related to use of the sanitize_uri function in lib/functions.php.
Cacti before 1.1.37 has XSS because it makes certain htmlspecialchars calls without the ENT_QUOTES flag (these calls occur when the html_escape function in lib/html.php is not used).
auth_login.php in Cacti before 1.0.0 allows remote authenticated users who use web authentication to bypass intended access restrictions by logging in as a user not in the cacti database, because the guest user is not considered. NOTE: this vulnerability exists because of an incomplete fix for CVE-2016-2313.
Cacti before 1.0.0 allows remote authenticated users to conduct PHP object injection attacks and execute arbitrary PHP code via a crafted serialized object, related to calling unserialize(stripslashes()).
Cross-site scripting (XSS) vulnerability in aggregate_graphs.php in Cacti before 1.1.16 allows remote authenticated users to inject arbitrary web script or HTML via specially crafted HTTP Referer headers, related to the $cancel_url variable. NOTE: this vulnerability exists because of an incomplete fix (lack of the htmlspecialchars ENT_QUOTES flag) for CVE-2017-11163.
auth_login.php in Cacti before 0.8.8g allows remote authenticated users who use web authentication to bypass intended access restrictions by logging in as a user not in the cacti database.
