SQL injection vulnerability in the graph settings script (graph_settings.php) in Cacti 0.8.8b and earlier allows remote attackers to execute arbitrary SQL commands via unspecified vectors.

The graph settings script (graph_settings.php) in Cacti 0.8.8b and earlier allows remote attackers to execute arbitrary commands via shell metacharacters in a font size, related to the rrdtool commandline in lib/rrd.php.

SQL injection vulnerability in cacti/host.php in Cacti 0.8.8b and earlier allows remote attackers to execute arbitrary SQL commands via the id parameter.

Multiple cross-site scripting (XSS) vulnerabilities in Cacti 0.8.8b and earlier allow remote attackers to inject arbitrary web script or HTML via (1) the step parameter to install/index.php or (2) the id parameter to cacti/host.php.

Multiple SQL injection vulnerabilities in (1) api_poller.php and (2) utility.php in Cacti before 0.8.8b allow remote attackers to execute arbitrary SQL commands via unspecified vectors.

(1) snmp.php and (2) rrd.php in Cacti before 0.8.8b allows remote attackers to execute arbitrary commands via shell metacharacters in unspecified vectors.

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.
