The server.php test script in ADOdb for PHP before 4.70, as used in multiple products including (1) Mantis, (2) PostNuke, (3) Moodle, (4) Cacti, (5) Xaraya, (6) PHPOpenChat, (7) MAXdev MD-Pro, and (8) MediaBeez, when the MySQL root password is empty, allows remote attackers to execute arbitrary SQL commands via the sql parameter.

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.

SQL injection vulnerability in config_settings.php for Cacti before 0.8.6e allows remote attackers to execute arbitrary SQL commands via the id parameter.

Cacti 0.8.5a allows remote attackers to gain sensitive information via an HTTP request to (1) auth.php, (2) auth_login.php, (3) auth_changepassword.php, and possibly other php files, which reveal the installation path in a PHP error message.

SQL injection vulnerability in auth_login.php in Cacti 0.8.5a allows remote attackers to execute arbitrary SQL commands and bypass authentication via the (1) username or (2) password parameters.
